public interface Signature
Represents the signature at a join point. This interface parallels
java.lang.reflect.Member
.
This interface is typically used for tracing or logging applications
to obtain reflective information about the join point, i.e. using
the j2se 1.4 java.util.logging
API
aspect Logging { Logger logger = Logger.getLogger("MethodEntries"); before(): within(com.bigboxco..*) && execution(public * *(..)) { Signature sig = thisJoinPoint.getSignature(); logger.entering(sig.getDeclaringType().getName(), sig.getName()); } }
More detailed information about a specific kind of signature can
be obtained by casting this Signature
object into one
of its more specific sub-types available in
org.aspectj.lang.reflect
.

getDeclaringTypeName()
Returns the fully-qualified name of the declaring type. |
int |
getModifiers()
Returns the modifiers on this signature represented as an int. |
String |
getName()
Returns the identifier part of this signature; i.e. |
String |
toLongString()
Returns an extended string representation of this signature. |
String |
toShortString()
Returns an abbreviated string representation of this signature. |

Class getDeclaringType()
Returns a java.lang.Class
object representing the class,
interface, or aspect that declared this member. For intra-member
declarations, this will be the type on which the member is declared,
not the type where the declaration is lexically written. Use
SourceLocation.getWithinType()
to get the type in
which the declaration occurs lexically.
For consistency with java.lang.reflect.Member
, this
method should have been named getDeclaringClass()
.
