getCallerClass
public static final Class getCallerClass(Class clazz)
throws SecurityException
Find the caller of the passed in Class.
May return null if caller not found on execution stack
clazz
- the Class to search for on stack to find caller of
- the Class of object that called parrameter class
getCallerClass
public static final Class getCallerClass(Class clazz,
int stackDepthOffset)
Find the caller of the passed in Class.
May return null if caller not found on execution stack
clazz
- the Class to search for on stack to find caller ofstackDepthOffset
- Offset call-stack depth to find caller
- the Class of object that called parrameter class
getCallerMethod
public static final String getCallerMethod(Class clazz)
Get the method path name for the method from which the LogEvent was
created, this includes the path name and the source filename and line
number if the source was compiled with debugging on.
clazz
- the Class to search for on stack to find caller of
- The method path name in the form "the.package.path.Method"
getRecentStack
public static final String getRecentStack(Class clazz,
int entries)
Return the current call stack as a String, starting with the first call
in the stack after a reference to the
clazz
class, and then
display
entries
entries.
This can be useful for debugging code to determine where calls to a
method are coming from.
clazz
- the last class on the stack you are not interested in!entries
- the number of stack lines to return.
- The method path name in the form "the.package.path.Method"
