- Enclosing interface:

public static interface JoinPoint.StaticPart
This helper object contains only the static information about a join point. It is available from the
JoinPoint.getStaticPart()
method, and can be accessed separately within advice using the special formthisJoinPointStaticPart
.If you are only interested in the static information about a join point, you should access it through this type for the best performance. This is particularly useful for library methods that want to do serious manipulations of this information, i.e.
public class LoggingUtils { public static void prettyPrint(JoinPoint.StaticPart jp) { ... } } aspect Logging { before(): ... { LoggingUtils.prettyPrint(thisJoinPointStaticPart); } }

Method Detail
-
getSignature
Signature getSignature()
Returns the signature at the join point.
-
getSourceLocation
SourceLocation getSourceLocation()
Returns the source location corresponding to the join point.
If there is no source location available, returns null.
Returns the SourceLocation of the defining class for default constructors.
-
getKind
java.lang.String getKind()
Returns a String representing the kind of join point. This String is guaranteed to be interned
-
getId
int getId()
Return the id for this JoinPoint.StaticPart. All JoinPoint.StaticPart instances are assigned an id number upon creation. For each advised type the id numbers start at 0.
The id is guaranteed to remain constant across repeated executions of a program but may change if the code is recompiled.
The benefit of having an id is that it can be used for array index purposes which can be quicker than using the JoinPoint.StaticPart object itself in a map lookup.
Since two JoinPoint.StaticPart instances in different advised types may have the same id, then if the id is being used to index some joinpoint specific state then that state must be maintained on a pertype basis - either by using pertypewithin() or an ITD.- Returns:
- the id of this joinpoint
-
toString
java.lang.String toString()
- Overrides:
toString
in classjava.lang.Object
-
toShortString
java.lang.String toShortString()
Returns an abbreviated string representation of the join point
-
toLongString
java.lang.String toLongString()
Returns an extended string representation of the join point
