Constructor Detail

BinaryCompositeSpacePredicate

protected BinaryCompositeSpacePredicate()

Default constructor for Externalizable.

BinaryCompositeSpacePredicate

protected BinaryCompositeSpacePredicate(ISpacePredicate leftOperand,
                                        ISpacePredicate rightOperand)

Creates a binary predicate using the specified operands.

Parameters:

leftOperand - Left operand of the binary predicate.

rightOperand - Right operand of the binary predicate.

Method Detail

getLeftOperand

public ISpacePredicate getLeftOperand()

Gets the left operand of this binary predicate.

Returns:

The left operand.

getRightOperand

public ISpacePredicate getRightOperand()

Gets the right operand of this binary predicate.

Returns:

The right operand.

execute

public boolean execute(Object target)

Description copied from interface: ISpacePredicate

Executes this predicate on the specified target.

Specified by:

execute in interface ISpacePredicate

Specified by:

execute in class AbstractSpacePredicate

Returns:

True if the specified target matches the predicate, false otherwise.

execute
