Class AbstractActionCondition

java.lang.Object

oracle.ifs.utils.action.AbstractActionCondition

All Implemented Interfaces:

ActionCondition

Direct Known Subclasses:

NumberActionCondition, StringActionCondition, VersionActionCondition

public abstract class AbstractActionCondition
extends Object
implements ActionCondition

A convenience class that adds operation validity check support and basic implementation for all the get and set methods in the interface. Subclasses should register their valid operations using addOperation() before any of their clients can set the current operation in setOperation(). Clients need also implement evaluate().

Constructs an ActionCondition initializing the validity check support.

Method Detail

getLeftOperand

public String getLeftOperand()

Returns the left operand.

Specified by:

getLeftOperand in interface ActionCondition

Returns:

String indicating the current left operand.

getRightOperand

public String getRightOperand()

Returns the right operand.

Specified by:

getRightOperand in interface ActionCondition

Returns:

String indicating the current right operand.

getOperation

public String getOperation()

Returns the current operation.

Specified by:

getOperation in interface ActionCondition

Returns:

String indicating the current operation.

setLeftOperand

public void setLeftOperand(String operand)

Sets the left operand for the current operation.

Specified by:

setLeftOperand in interface ActionCondition

Parameters:

operand - String specifying the left operand.

setRightOperand

public void setRightOperand(String operand)

Sets the right operand for the current operation.

Specified by:

setRightOperand in interface ActionCondition

Parameters:

operand - String specifying the right operand.

setOperation

public void setOperation(String operation)

Sets the operation to perform on the left and right operands.

Specified by:

setOperation in interface ActionCondition

Parameters:

operation - String specifying the operation.

Throws:

IllegalArgumentException - If an invalid operation is specified.

addOperation

protected void addOperation(String operation)

Adds an operation to the valid list of operations. Subclasses should register all the operations they support before a call to setOperation() is made by any of their clients (unless the default behavior and operation validity chack in setOperation() is changed.)

Parameters:

operation - String A supported operation.
