org.codehaus.aspectwerkz.expression.ExpressionInfo
Abstraction that holds info about the expression and the different visitors.
We are using a lazy initialization for m_hasCflowPointcut field to allow to fully resolve each expression (that is f.e. on IBM compiler, fields are in the reverse order, thus pointcut reference in aspect defined with annotations may not be resolved until the whole class has been parsed. @author Jonas Bon�r @author Alexandre Vasseur
