Constructor Detail

SimpleMathCalcStep

public SimpleMathCalcStep()

Default constructor for SimpleMath calculation step.

Method Detail

equals

public boolean equals(java.lang.Object obj)

Tests this Step for true equality

Overrides:

equals in class CalcStep

Parameters:

obj - Step to compare it to

Returns:

true if completely internally equal

getMeasureDependencyIDs

public java.util.Vector getMeasureDependencyIDs(java.lang.String measDim)

Get measure unique ID dependencies in this step

Overrides:

getMeasureDependencyIDs in class CalcStep

Parameters:

measDim - the measure dimension ID for those steps that need to know if they have measure members

Returns:

Vector of measures this step depends on, as unique ID Strings null if none

getLeftOperand

public CalcValue getLeftOperand()

Retrieves the left side operand.

Returns:

CalcValue which represents the left side operand.

setLeftOperand

public void setLeftOperand(CalcValue leftOperand)

Sets the left side operand.

Parameters:

leftOperand - A CalcValue value that represents the left side operand.

getRightOperand

public CalcValue getRightOperand()

Retrieves the right side operand.

Returns:

CalcValue which represents the right side operand.

setRightOperand

public void setRightOperand(CalcValue rightOperand)

Sets the right side operand.

Parameters:

rightOperand - A CalcValue value that represents the right side operand.

clone

public java.lang.Object clone()

Implements the clone method.

Overrides:

clone in class CalcStep

Returns:

Object which represents a clone of this SimpleMath calculation object.

getViewClassName

public java.lang.String getViewClassName()

Retrieves the view class name name associated with the calc. Note: If the view class name is null, the Template page in the wizard will be omitted, and the user will be taken directly to the Custom Formula Editor page

Overrides:

getViewClassName in class CalcStep

Returns:

String which represents the view class name.

getEvaluatorClassName

public java.lang.String getEvaluatorClassName()

Retrieves the evaluator class name name associated with the calc.

Overrides:

getEvaluatorClassName in class CalcStep

Returns:

String which represents the evaluator class name.

getEvaluatorClass

public java.lang.Class getEvaluatorClass()
                                  throws SelectionException

Retrieves the StepEvaluator class object that is associated with this Step object. The QueryServer object uses this class to instantiate the appropriate StepEvaluator object.

Overrides:

getEvaluatorClass in class Step

Returns:

The Class object.

Throws:

SelectionException - If the StepEvaluator class is not found.

toString

public java.lang.String toString()

Generates the string representation of this SimpleMathCalcStep object.

Overrides:

toString in class CalcStep

Returns:

The string representation of this SimpleMathCalcStep object.

getXML

public java.lang.Object getXML( context)

Returns the XML representation of the object. Note that XML representation can be of any type. The XML returned could contain only partial updates of the states. However, it is up to the implementor to decide whether this should be supported. (i.e. Not mandatory)

Overrides:

getXML in class CalcStep

Parameters:

context - The control settings that is send by the container (caller)

Returns:

The XML representation of the object

See Also:

ObjectScope

setXML

public void setXML( context,
                   java.lang.Object node)

Sets the XML representation of the object. Note that XML representation can be of any type.

Overrides:

setXML in class CalcStep

Parameters:

context - The control settings that is send by the container (caller)

node - The XML representation of the object
