Constructor Details

UnaryCompositeSpacePredicate

protected UnaryCompositeSpacePredicate()

Default constructor for Externalizable.

UnaryCompositeSpacePredicate

protected UnaryCompositeSpacePredicate(ISpacePredicate operand)

Creates an unary predicate using the specified operands.

Parameters:

operand - Operand for unary predicate.

Method Details

getOperand

public ISpacePredicate getOperand()

Gets the operand of this unary predicate.

Returns:

the operand of this unary predicate.

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

protected abstract boolean execute(Object target,
 ISpacePredicate operand)

Executes the operand predicate on the target.

Parameters:

target - Target object for predicate execution.

operand - Predicate to execute.

toString

public String toString()

Overrides:

toString in class Object

getOperatorName

protected abstract String getOperatorName()

Gets this operator's name, to be used in toString().

Returns:

This operator's name.
