org.eclipse.core.expressions
Class EvaluationResult

java.lang.Object
  extended by 
org.eclipse.core.expressions.EvaluationResult

public class EvaluationResult
extends Object

An evaluation result represents the result of an expression evaluation. There are exact three instances of evaluation result. They are: FALSE, TRUE and NOT_LOADED. NOT_LOADED represents the fact that an expression couldn't be evaluated since a plug-in providing certain test expressions isn't loaded yet.

In addition the class implements the three operation and , or and not. The operation are defined as follows:

The and operation:

AND FALSE TRUE NOT_LOADED
FALSE FALSE FALSE FALSE
TRUE FALSE TRUE NOT_LOADED
NOT_LOADED FALSE NOT_LOADED NOT_LOADED

The or operation:

OR FALSE TRUE NOT_LOADED
FALSE FALSE TRUE NOT_LOADED
TRUE TRUE TRUE TRUE
NOT_LOADED NOT_LOADED TRUE NOT_LOADED

The not operation:

NOT FALSE TRUE NOT_LOADED
TRUE FALSE NOT_LOADED

The class is not intended to be subclassed by clients.

Since:
3.0
Restriction:
This class is not intended to be subclassed by clients.
