Class LessFilter<E>

Filter which compares the result of a method invocation with a value for Less condition. In a case when either result of a method invocation or a value to compare are equal to null, the evaluate test yields false. This approach is equivalent to the way the NULL values are handled by SQL.

Type Parameters

  • E = any

    the type of the value to use for comparison

Constructors

constructor

  • Construct a LessFilter for testing Less condition.

    Type Parameters

    • E = any

    Parameters

    • extractorOrMethod: string | ValueExtractor

      the extractor.ValueExtractor to use by this filter or the name of the method to invoke via reflection

    • value: E

      the object to compare the result with

    Returns LessFilter<E>

Properties

@class

@class: string

Server-side Filter implementation type identifier.

Protected extractor

extractor: ValueExtractor

The ValueExtractor used by this Filter.

Protected value

value: E

The value to compare to.

Methods

and

  • Return a composed filter that represents a short-circuiting logical AND of this filter and another. When evaluating the composed filter, if this filter is `false, then the other filter is not evaluated.

    Any exceptions thrown during evaluation of either filter are relayed to the caller; if evaluation of this filter throws an exception, the *other* filter will not be evaluated.

    @param other a filter that will be logically-ANDed with this filter

    @return a composed filter that represents the short-circuiting logical AND of this filter and the other filter

    Parameters

    Returns Filter

associatedWith

forKeys

  • Return a filter that will only be evaluated within specified key set.

    Returns

    a key set-limited filter

    Type Parameters

    • K = any

    Parameters

    • keys: Set<K>

      the set of keys to limit the filter evaluation to

    Returns InKeySetFilter<K>

or

  • Return a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.

    Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the *other* predicate will not be evaluated.

    Returns

    a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate

    Parameters

    • other: Filter

      a predicate that will be logically-ORed with this predicate

    Returns Filter

xor

  • Return a composed predicate that represents a logical XOR of this predicate and another.

    Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

    Returns

    a composed predicate that represents the logical XOR of this predicate and the 'other' predicate

    Parameters

    • other: Filter

      a predicate that will be logically-XORed with this predicate

    Returns Filter
