Creates a operate that invokes func with the arguments of the created function. If func is a property name, the created operate returns the property worth for a given element. If func is an array or object, the created operate returns true for components that comprise the equal supply properties, in any different case it returns false. For strings and array-like objects _.isEmpty checks if the size property is 0.
For different objects, it returns true if the thing has no enumerable own-properties. Note that primitive numbers, booleans and symbols are continually empty by this definition. Its iterator() approach is predicted to generate a dataset iterator object, the next() approach to which is predicted to supply statistics batches for training. The return worth of the next() name must comprise a boolean accomplished subject and a worth field.
The worth area is predicted to be an array of two tf.Tensors or an array of two nested tf.Tensor structures. The former case is for fashions with precisely one enter and one output (e.g.. a sequential model). The latter case is for fashions with a number of inputs and/or a number of outputs. Of the 2 gadgets within the array, the primary is the enter function and the second is the output target. Its iterator() technique is predicted to generate a dataset iterator object, the next() approach to which is predicted to supply information batches for evaluation. Or possibly you wish to deal with them as zeros; it really is as much as you.
The similar iterateecan even be handed to different Underscore features making positive that the conduct is consistent. Requests further attributes for the given feature. In some profiles, similar to Visualization and Labeling, apps solely request the info attributes required for rendering every function or label. Some expressions dynamically reference subject names with variables slightly then string literals. This makes it tough for rendering and labeling engines to detect fields required for rendering. This perform lets you explicitly point out required fields as a list.
You additionally can request all or a subset of fields making use of a wildcard. Because expressions execute on a per function basis, the wildcard ought to be used with caution, primarily in layers containing many features. Requesting an excessive amount of info may end up in very poor app performance. Indicates whether or not all the weather in a given array move a check from the presented function. Returns true if the operate returns true for all gadgets within the enter array. Takes a spec object and a check object; every of the spec's personal properties have to be a predicate function.
Each predicate is utilized to the worth of the corresponding property of the check object. WhereAny returns true if at the very least considered one of many predicates return true, false otherwise. Takes a spec object and a check object; returns true if the check satisfies the spec. Each of the spec's very own properties have to be a predicate function.
Where returns true if all of the predicates return true, false otherwise. Assigns personal and inherited enumerable string keyed properties of supply objects to the vacation spot object for all vacation spot properties that resolve to undefined. Once a property is set, further values of the identical property are ignored. Added an _.defaults function, to be used merging mutually JS objects representing default options. Added an _.once function, for manufacturing capabilities that ought to solely ever execute a single time.
_.bind now delegates to the native ES5 version, the place available. _.keys now throws an error when used on non-Object values, as in ES5. Fixed a bug with _.keys when used over sparse arrays. Memoizes a given perform by caching the computed result. Useful for rushing up slow-running computations. If handed an non-compulsory hashFunction, it is going to likely be used to compute the hash key for storing the result, structured on the arguments to the unique function.
The default hashFunction simply makes use of the primary argument to the memoized operate because the key. The cache of memoized values is accessible because the cacheproperty on the returned function. A assortment of Realm Objects will be sorted on a number of properties of these objects, or of properties of objects linked to by these objects. To type by a single property, merely move the identify of that property tosorted(), optionally adopted by a boolean indicating if the type ought to be reversed. For multiple property, you need to move an array ofsort descriptors which listing which properties to type on.
Query consequences are continually sorted by the type key value. If the info variety of the type secret is Number, the outcomes are returned in numeric order; otherwise, the outcomes are returned so as of UTF-8 bytes. To reverse the order, set the ScanIndexForward parameter to false. Tests regardless of whether or not not considered one of many weather in a given array cross a take a look at from the presented function. Returns true if the testFunction returns false for all gadgets within the enter array. Tests regardless of whether or not any of the weather in a given array cross a take a look at from the presented function.
Returns true if the perform returns true for at the very least one merchandise within the enter array. Returns a function, fn, which encapsulates if/else, if/else, ... If not one among many predicates matches, fn returns undefined. This way is like _.assign besides that it recursively merges very own and inherited enumerable string keyed properties of supply objects into the vacation spot object. Source properties that resolve to undefined are skipped if a vacation spot worth exists. Array and plain object properties are merged recursively.
Other objects and worth varieties are overridden by assignment. Subsequent sources overwrite property assignments of past sources. Keep in mind, the form of the output tensor can differ counting on what percentage true values there are in input. The ensuing tensor has the form [numTrueElems, condition.rank].
Added _.groupBy, which aggregates a set into teams of like items. Added _.union and _.difference, to enrich the (re-named) _.intersection. Various advancements for assist of sparse arrays.
_.toArray now returns a clone, if immediately exceeded an array. _.functions now additionally returns the names of capabilities which are current within the prototype chain. The logical NOT (!) operator takes fact to falsity and vice versa.
When used with non-Boolean values, it returns false if its single operand would be transformed to true; otherwise, returns true. Receives one argument, seed, and returns both false to give up iteration or an array of size two to proceed. The aspect at index zero of this array will probably be added to the ensuing array, and the aspect at index 1 will probably be handed to the subsequent name to fn.
Like reduce, reduceWhile returns a single merchandise by iterating as a result of the list, successively calling the iterator function. ReduceWhilealso takes a predicate that's evaluated earlier than every step. If the predicate returns false, it "short-circuits" the iteration and returns the present worth of the accumulator. ReduceWhile might alternatively be short-circuited by way of reduced.
Accepts a converging operate and an inventory of branching capabilities and returns a brand new function. The arity of the brand new operate is identical because the arity of the longest branching function. When invoked, this new operate is utilized to some arguments, and every branching operate is utilized to these self identical arguments. The effects of every branching operate are exceeded as arguments to the converging operate to supply the return value.
Array-like values comparable to arguments objects, arrays, buffers, strings, or jQuery-like collections are regarded empty if they've a measurement of 0. Similarly, maps and units are regarded empty if they've a measurement of 0. Gets the dimensions of assortment by returning its measurement for array-like values or the variety of personal enumerable string keyed properties for objects. Invokes the tactic at path of every component in collection, returning an array of the outcomes of every invoked method.
Any further arguments are presented to every invoked method. If path is a function, this is invoked for, and this sure to, every component in collection. _.bindAll now takes the context object as its first parameter.
If no methodology names are passed, all the context object's techniques are sure to it, enabling chaining and more straightforward binding. _.functions now takes a single argument and returns the names of its Function properties. Calling _.functions will get you the earlier behavior.
Added _.isRegExp in order that isEqual can now take a look at for RegExp equality. All of the "is" features have been shrunk down right into a single definition. In classical programming, the logical OR is supposed to control boolean values only. If any of its arguments are true, it returns true, in any different case it returns false. If ScanIndexForward is true, DynamoDB returns the outcomes within the order through which they're saved .
If ScanIndexForward is false, DynamoDB reads the outcomes in reverse order by type key value, after which returns the outcomes to the client. You have to present the identify of the partition key attribute and a single worth for that attribute. Query returns all gadgets with that partition key value.
Optionally, you'll be able to give a kind key attribute and use a assessment operator to refine the search results. If all of the gadgets within the array are the identical type, an proper kind perform will probably be used. If they're totally different types, the gadgets will probably be changed to strings.
If the array comprises objects, and no consumer outlined operate is provided, no variety will happen. Creates a brand new operate that, when invoked, caches the results of calling fnfor a given argument set and returns the result. Adds all personal enumerable string keyed operate properties of a supply object to the vacation spot object. If object is a function, then techniques are added to its prototype as well.
The reverse of _.method; this methodology creates a perform that invokes the tactic at a given path of object. Any further arguments are supplied to the invoked method. This operation has the identical semantics as reshape on the represented dense tensor. The inputIndices are recomputed structured on the requested newShape.
If one aspect of newShape is the exceptional worth -1, the dimensions of that dimension is computed in order that the overall dense measurement stays constant. The variety of dense parts implied by newShape have to be similar to the variety of dense parts initially implied by inputShape. Reshaping doesn't influence the order of values within the SparseTensor. It additionally returns a tensorindices the identical measurement because the variety of the weather in x alongside the axisdimension. It consists of the index within the distinctive output values.
Reduces the enter alongside the size given in axis. Unless keepDimsis true, the rank of the array is decreased by 1 for every entry in axis. If keepDims is true, the decreased dimensions are retained with size 1. If axis has no entries, all dimensions are reduced, and an array with a single component is returned.
Added _.after, which can return a operate that solely runs after first being referred to as a specified variety of times. _.invoke can now take a direct operate reference. _.every now requires an iterator operate to be passed, which mirrors the ES5 API. _.extend not copies keys when the worth is undefined. _.bind now errors when attempting to bind an undefined value. Set to true to trigger the corresponding attribute to be set on the host node when the property worth changes.
If the property worth is Boolean, the attribute is created as an average HTML boolean attribute . For different property types, the attribute worth is a string illustration of the property value. See Reflecting properties to attributes for extra information. Use the KeyConditionExpression parameter to offer a selected worth for the partition key.
The Query operation will return all the gadgets from the desk or index with that partition key value. You can optionally slender the scope of the Query operation by specifying a kind key worth and a comparability operator in KeyConditionExpression. To additional refine the Query results, you'll optionally supply a FilterExpression. A FilterExpression determines which gadgets inside the outcomes ought to be returned to you. Uses the prevailing isEmpty Arcade operate because the testFunction.
