Method Detail

negate

public Expression negate()

Description copied from interface: Expression

Returns the negation of this expression, equivalent to not(this).

literal

public Literal<T> literal()

isLiteralPredicate

public boolean isLiteralPredicate()

Overrides:

isLiteralPredicate in class BoundPredicate<T>

asLiteralPredicate

public BoundLiteralPredicate<T> asLiteralPredicate()

Overrides:

asLiteralPredicate in class BoundPredicate<T>

test

public boolean test(T value)

Specified by:

test in class BoundPredicate<T>

isEquivalentTo

public boolean isEquivalentTo(Expression expr)

Description copied from interface: Expression

Returns whether this expression will accept the same values as another.

If this returns true, the expressions are guaranteed to return the same evaluation for the same input. However, if this returns false the expressions may return the same evaluation for the same input. That is, expressions may be equivalent even if this returns false.

For best results, rewrite not and bind expressions before calling this method.

Parameters:

expr - another expression

Returns:

true if the expressions are equivalent

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
