Interface ActionCondition

All Known Implementing Classes:

AbstractActionCondition, NumberActionCondition, StringActionCondition, VersionActionCondition

public interface ActionCondition

The ActionCondition interface defines the general contract for classes that represent specific types of conditions wrapping action definitions in an XML list of actions.

Method Summary

Modifier and Type	Method and Description
boolean	evaluate() Evaulates the current operation set on the ActionCondition given the current left and right operands.
String	getLeftOperand() Returns the left operand.
String	getOperation() Returns the current operation.
String	getRightOperand() Returns the right operand.
void	setLeftOperand(String operand) Sets the left operand for the current operation.
void	setOperation(String operation) Sets the operation to perform on the left and right operands.
void	setRightOperand(String operand) Sets the right operand for the current operation.

Method Detail

setOperation

void setOperation(String operation)

Sets the operation to perform on the left and right operands. Clients of ActionCondition define their own set of valid operations and their semantics.

Parameters:

operation - String specifying the operation.

Throws:

IllegalArgumentException - If an invalid operation is specified.

setLeftOperand

void setLeftOperand(String operand)

Sets the left operand for the current operation.

Parameters:

operand - String specifying the left operand.

setRightOperand

void setRightOperand(String operand)

Sets the right operand for the current operation.

Parameters:

operand - String specifying the right operand.

getOperation

String getOperation()

Returns the current operation.

Returns:

String indicating the current operation.

getLeftOperand

String getLeftOperand()

Returns the left operand.

Returns:

String indicating the current left operand.

getRightOperand

String getRightOperand()

Returns the right operand.

Returns:

String indicating the current right operand.

evaluate

boolean evaluate()

Evaulates the current operation set on the ActionCondition given the current left and right operands. The evaluate() method should always return the same value if the operation and the operands are not changed.

Returns:

true if the operation succeeds; false otherwise. Each valid operation in a specific ActionCondition subclass defines its own semantics for success and failure.
