Contains definitions of functions and predicates.
  • Class
    Description
    BigDecimalFunction1<T0>
    Function that takes one parameter and returns a BigDecimal value.
    Deterministic
    Specifies that function is deterministic (i.e.
    DoubleFunction1<T0>
    Function that takes one parameter and returns a native double value.
    EqualityComparer<T>
    Compares values for equality.
    Experimental
    Annotation that indicates that a class, interface, field or method is experimental, not part of the public API, and subject to change or removal.
    FloatFunction1<T0>
    Function that takes one parameter and returns a native float value.
    Function<R>
    Base interface for all functions.
    Function0<R>
    Function with no parameters.
    Function1<T0,R>
    Function with one parameter.
    Function2<T0,T1,R>
    Function with two parameters.
    Functions
    Utilities relating to functions.
    Hints
    Annotation applied to a user-defined function that gives extra metadata about that function.
    IntegerFunction1<T0>
    Function that takes one parameter and returns a native int value.
    LongFunction1<T0>
    Function that takes one parameter and returns a native long value.
    NonDeterministic
    Specifies that function is NOT deterministic (i.e.
    NullableBigDecimalFunction1<T0>
    Function that takes one parameter and returns a BigDecimal value that may be null.
    NullableDoubleFunction1<T0>
    Function that takes one parameter and returns a Double value that may be null.
    NullableFloatFunction1<T0>
    Function that takes one parameter and returns a Float value that may be null.
    NullableIntegerFunction1<T0>
    Function that takes one parameter and returns an Integer value that may be null.
    NullableLongFunction1<T0>
    Function that takes one parameter and returns a Long value that may be null.
    Parameter
    Annotation that supplies metadata about a function parameter.
    Predicate1<T0>
    Function with one parameter returning a native boolean value.
    Predicate2<T0,T1>
    Function with two parameters returning a native boolean value.
    SemiStrict
    Annotation applied to a user-defined function that indicates that the function always returns null if one or more of its arguments are null but also may return null at other times.
    Strict
    Annotation applied to a user-defined function that indicates that the function returns null if and only if one or more of its arguments are null.
