  +--oracle.cabo.ui.data.bind.ComparisonBoundValue

All Implemented Interfaces:

BoundValue

public class ComparisonBoundValue

extends java.lang.Object

implements BoundValue

Booolean BoundValue that compares either two BoundValues or a BoundValues and an Object with a comparison operator and returns the Boolean result.

Only BoundValues that return java.lang.Numbers or java.lang.Numbers can be used with comparisons other than COMPARISON_EQUALS and COMPARISON_NOT_EQUALS

Field Summary

static int	COMPARISON_EQUALS True if the left and right sides are equivalent.
static int	COMPARISON_GREATER_THAN True if the left side is greater than the right side.
static int	COMPARISON_GREATER_THAN_OR_EQUALS True if the left side is greater than or equal to the right side.
static int	COMPARISON_LESS_THAN True if the left side is less than the right side.
static int	COMPARISON_LESS_THAN_OR_EQUALS True if the left side is less than or equal to the right side.
static int	COMPARISON_NOT_EQUALS True if the left and right sides are not equivalent.

Constructor Summary

ComparisonBoundValue(int comparison, BoundValue leftSideValue, BoundValue rightSideValue)

ComparisonBoundValue(int comparison, BoundValue leftSideValue, java.lang.Object rightSide)

Method Summary

static ComparisonBoundValue	createExistsValue(BoundValue existenceValue)
java.lang.Object	getValue(RenderingContext context) Calculates the current state of the model.

Field Detail

COMPARISON_EQUALS

public static final int COMPARISON_EQUALS

True if the left and right sides are equivalent.

True if the left side is less than the right side.

This requires that both sides be or return java.lang.Numbers.

COMPARISON_LESS_THAN_OR_EQUALS

public static final int COMPARISON_LESS_THAN_OR_EQUALS

True if the left side is less than or equal to the right side.

This requires that both sides be or return java.lang.Numbers.
