- public class ParamReader
- extends ClassReader
This is the class file reader for obtaining the parameter names
for declared methods in a class. The class must have debugging
attributes for us to obtain this information.
This does not work for inherited methods. To obtain parameter
names for inherited methods, you must use a paramReader for the
class that originally declared the method.
don't get tricky, it's the bare minimum. Instances of this class
are not threadsafe -- don't share them.

ParamReader
public ParamReader(java.lang.Class c)
throws java.io.IOException
- process a class file, given it's class. We'll use the defining
classloader to locate the bytecode.
- Parameters:
c
- - Throws:
java.io.IOException
-
ParamReader
public ParamReader(byte[] b)
throws java.io.IOException
- process the given class bytes directly.
- Parameters:
b
- - Throws:
java.io.IOException
-
readCode
public void readCode()
throws java.io.IOException
- Description copied from class:
ClassReader
- read a code attribute
- Overrides:
readCode
in class ClassReader
- Following copied from class:
org.apache.axis.utils.bytecode.ClassReader
- Throws:
java.io.IOException
-
getParameterNames
public java.lang.String[] getParameterNames(java.lang.reflect.Method method)
- return the names of the declared parameters for the given method.
If we cannot determine the names, return null. The returned array will
have one name per parameter. The length of the array will be the same
as the length of the Class[] array returned by Method.getParameterTypes().
- Parameters:
method
- - Returns:
- String[] array of names, one per parameter, or null
readLocalVariableTable
public void readLocalVariableTable()
throws java.io.IOException
- this is invoked when a LocalVariableTable attribute is encountered.
- Throws:
java.io.IOException
