WithExpression

public WithExpression(IConfigurationElement configElement)
               throws CoreException

Throws:

CoreException

WithExpression

public WithExpression(Element element)
               throws CoreException

Throws:

CoreException

WithExpression

public WithExpression(String variable)

Method Detail

equals

public boolean equals(Object object)

Overrides:

equals in class Object

computeHashCode

protected int computeHashCode()

Description copied from class: Expression

Method to compute the hash code for this object. The result returned from this method in cached in the fHashCode field. If the value returned from the method equals Expression.HASH_CODE_NOT_COMPUTED (e.g. -1) then the value is incremented by one.

This default implementation calls super.hashCode()

Overrides:

computeHashCode in class CompositeExpression

Returns:

a hash code for this object.

evaluate

public EvaluationResult evaluate(IEvaluationContext context)
                          throws CoreException

Description copied from class: Expression

Evaluates this expression.

Specified by:

evaluate in class Expression

Parameters:

context - an evaluation context providing information like variable, name spaces, etc. necessary to evaluate this expression

Returns:

the result of the expression evaluation

Throws:

CoreException - if the evaluation failed. The concrete reason is defined by the subclass implementing this method

collectExpressionInfo

public void collectExpressionInfo(ExpressionInfo info)

Description copied from class: Expression

Collects information about this expression tree. This default implementation add the expression's type to the set of misbehaving expression types.

Overrides:

collectExpressionInfo in class CompositeExpression

Parameters:

info - the expression information object used to collect the information

toString

public String toString()

Overrides:

toString in class CompositeExpression
