 ch.ethz.prose.crosscut.SignaturePattern
All known Subclasses: ch.ethz.prose.crosscut.SetGetSignaturePattern, ch.ethz.prose.crosscut.MethodCutSignaturePattern, ch.ethz.prose.crosscut.CatchHandleSignaturePattern, ch.ethz.prose.crosscut.ConstructorCutSignaturePattern, ch.ethz.prose.crosscut.ThrowHandleSignaturePattern,
| SignaturePattern | | abstract public class SignaturePattern (Code) | | Every Crosscut contains a method to be executed when a join-point is hit.
In the case of MethodCut objects, the SignaturePattern has three
roles:
- The pattern role: through a special signature, define matches for the
target class, and for the parameters of the methods belonging to the target.
- The method finder role: determine which method o of the crosscut
must be ivoked upon a hit join-point.
- The optimization role: to cathegorize the signature of the advice
method, such that the subsequent execution of the advice method is efficient.
The categorization is currently performed according to the
SIGNATURE__XXX
constants.

methodObj.getParameterTypes(). Present
for efficiency reasons.

| isAssignable | | protected boolean isAssignable(Class[] actualParameterType, Class formalParameterType)(Code) | | |
| matchesTarget | | protected boolean matchesTarget(Class actualClass)(Code) | | When no advice action is set, it returns true.
If an advice action exists, it returns true
if the pattern-matching signature acepts actualClass
as a potential crosscut class.
