Constructor Detail

MultipleCompositeSpacePredicate

public MultipleCompositeSpacePredicate()

Default constructor for Externalizable.

MultipleCompositeSpacePredicate

public MultipleCompositeSpacePredicate(List<ISpacePredicate> operands)

Creates a multiple composite space predicate using the specified operands.

MultipleCompositeSpacePredicate

public MultipleCompositeSpacePredicate(ISpacePredicate... operands)

Creates a multiple composite space predicate using the specified operands.

Method Detail

getNumOfOperands

public int getNumOfOperands()

Gets the number of operands in this composite predicate.

getOperand

public ISpacePredicate getOperand(int index)

Gets the operand at the specified index.

Parameters:

index - Index of operand to get.

Returns:

Operand at specified index.

setOperand

public void setOperand(int index,

Parameters:

index - Index of operand to set.

operand - new operand.

addOperand

public void addOperand(ISpacePredicate operand)

Adds an operand at the end of the current operands list.

Parameters:

operand - Operand to add.

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:
