Interface Signature

All Known Subinterfaces:
  AdviceSignature, CatchClauseSignature, CodeSignature, ConstructorSignature, FieldSignature, InitializerSignature, MemberSignature, MethodSignature

All Known Implementing Classes:
  FieldSignatureImpl

    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`.

See Also:
  `Member`, `java.util.logging.Logger`

Method Summary
`java.lang.Class` | `getDeclaringType()` Returns a `java.lang.Class` object representing the class, interface, or aspect that declared this member.
`java.lang.String` | `getDeclaringTypeName()` Returns the fully-qualified name of the declaring type.
`int` | `getModifiers()` Returns the modifiers on this signature represented as an int.
`java.lang.String` | `getName()` Returns the identifier part of this signature.
`java.lang.String` | `toLongString()` Returns an extended string representation of this signature.
`java.lang.String` | `toShortString()` Returns an abbreviated string representation of this signature.
`java.lang.String` | `toString()`

Method Detail

### toString

    java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`

### toShortString

    java.lang.String toShortString()

  Returns an abbreviated string representation of this signature.

### toLongString

    java.lang.String toLongString()

  Returns an extended string representation of this signature.

### getName

    java.lang.String getName()

  Returns the identifier part of this signature. For methods this will return the method name.

  See Also:
    `Member.getName()`

### getModifiers

    int getModifiers()

  Returns the modifiers on this signature represented as an int. Use the constants and helper methods defined on `java.lang.reflect.Modifier` to manipulate this, i.e.

           // check if this signature is public
           java.lang.reflect.Modifier.isPublic(sig.getModifiers());

           // print out the modifiers
           java.lang.reflect.Modifier.toString(sig.getModifiers());

  See Also:
    `Member.getModifiers()`, `Modifier`

### getDeclaringType

    java.lang.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()`.

  See Also:
    `Member.getDeclaringClass()`

### getDeclaringTypeName

    java.lang.String getDeclaringTypeName()

  Returns the fully-qualified name of the declaring type. This is equivalent to calling getDeclaringType().getName(), but caches the result for greater efficiency.
