AspectJ Weaver 1.9.20.1 · org.aspectj.lang.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.

Method Summary

Modifier and Type	Method and Description
public Class<T>	Returns: the class, interface or aspect that declared this member getDeclaringType() Returns a `java.lang.Class` object representing the class, interface, or aspect that declared this member.
public String	Returns: the fully qualified name of the declaring type getDeclaringTypeName() This is equivalent to calling getDeclaringType().getName(), but caches the result for greater efficiency.
public int	Returns: the modifiers on this signature represented as an int getModifiers() Returns the modifiers on this signature represented as an int.
public String	Returns: the identifier part of this signature. For methods this will return the method name. getName()
public String	Returns: an extended string representation of this signature. toLongString()
public String	Returns: an abbreviated string representation of this signature. toShortString()
public String	toString()

getDeclaringType back to summary

getDeclaringType	back to summary
public Class<T> 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()`. Returns:Class<T> the class, interface or aspect that declared this member See Also `java.lang.reflect.Member#getDeclaringClass`

public Class<T> 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().

Returns:Class<T>: the class, interface or aspect that declared this member
See Also: java.lang.reflect.Member#getDeclaringClass

getDeclaringTypeName	back to summary
public String getDeclaringTypeName() This is equivalent to calling getDeclaringType().getName(), but caches the result for greater efficiency. Returns:String the fully qualified name of the declaring type

getDeclaringTypeName

back to summary

public String getDeclaringTypeName()

This is equivalent to calling getDeclaringType().getName(), but caches the result for greater efficiency.

Returns:String: the fully qualified name of the declaring type

getModifiers back to summary

getModifiers	back to summary
public 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()); Returns:int the modifiers on this signature represented as an int See Also `java.lang.reflect.Member#getModifiers`, `java.lang.reflect.Modifier`

public 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());

Returns:int: the modifiers on this signature represented as an int
See Also: java.lang.reflect.Member#getModifiers, java.lang.reflect.Modifier

getName	back to summary
public String getName() Returns:String the identifier part of this signature. For methods this will return the method name. See Also `java.lang.reflect.Member#getName`

toLongString	back to summary
public String toLongString() Returns:String an extended string representation of this signature.

toShortString	back to summary
public String toShortString() Returns:String an abbreviated string representation of this signature.

toString	back to summary
public String toString()
