   org.apache.axis2.description.java2wsdl.bytecode.ParamReader

ParamReader
public class ParamReader extends ClassReader (Code)
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.




Constructor Summary
public  ParamReader(Class c)
     Processes a class file, given it's class.
public  ParamReader(byte[] b)
     Processes the given class bytes directly.

Method Summary
public  String[]getParameterNames(Constructor ctor)
     Returns the names of the declared parameters for the given constructor. If we cannot determine the names, return null.
public  String[]getParameterNames(Method method)
     Returns the names of the declared parameters for the given method. If we cannot determine the names, return null.
protected  String[]getParameterNames(Member member, Class[] paramTypes)
    
public  voidreadCode()
    
public  voidreadLocalVariableTable()
     This is invoked when a LocalVariableTable attribute is encountered.


Constructor Detail
ParamReader
public ParamReader(Class c) throws IOException(Code)
Processes 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 IOException(Code)
Processes the given class bytes directly.
Parameters:
  b -
throws:
  IOException -




Method Detail
getParameterNames
public String[] getParameterNames(Constructor ctor)(Code)
Returns the names of the declared parameters for the given constructor. 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 Constructor.getParameterTypes().
Parameters:
  ctor - Returns String[] array of names, one per parameter, or null



getParameterNames
public String[] getParameterNames(Method method)(Code)
Returns 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



getParameterNames
protected String[] getParameterNames(Member member, Class[] paramTypes)(Code)



readCode
public void readCode() throws IOException(Code)



readLocalVariableTable
public void readLocalVariableTable() throws IOException(Code)
This is invoked when a LocalVariableTable attribute is encountered.
throws:
  IOException -
