All Implemented Interfaces:

java.lang.Cloneable, Discriminator, DiscriminatorXML, java.io.Serializable

public class PositionDiscriminator

extends java.lang.Object

implements DiscriminatorXML

Discriminator for a rule that applies when a DataView item is in a particular location. For example, you could use this Discriminator to specify that a DiscriminatorRule should apply to the first row in a crosstab or table.

This Discriminator compares an internal ComponentInfo class to a ComponentInfo class that is in the RuleContext that describes the item to be painted.

Parameters:

componentInfo - The ComponentInfo object that specifies the position that a DataView item must occupy in order for this PositionDiscriminator to apply.

Method Detail

clone

public java.lang.Object clone()

Clones this PositionDiscriminator.

Specified by:

clone in interface Discriminator

Returns:

The clone of this PositionDiscriminator.

getComponentInfo

public ComponentInfo getComponentInfo()

Retrieves the ComponentInfo object of this PositionDiscriminator.

Returns:

The ComponentInfo object that specifies the position that a DataView item must occupy in order for this PositionDiscriminator to apply.

setComponentInfo

public void setComponentInfo(ComponentInfo componentInfo)

Specifies the ComponentInfo object for this PositionDiscriminator.

Parameters:

componentInfo - The ComponentInfo object that specifies the position that a DataView item must occupy in order for this PositionDiscriminator to apply.
