Method Detail

runMethod

public static Object runMethod(Object o,
                               String method,
                               String params)
                        throws CallerFailedException

Will call a method on an object given a string that can be parsed into a list of arguments. This method works by selecting all plausible methods from the object and trying them by calling the other runMethod method (the one that takes method as a Method object rather than a string)

Returns:

the return value of the method turned into an object

Throws:

CallerFailedException - if an error occurs

getMethods

public static Vector getMethods(Object o,
                                String method)

Returns all methods with a given name for a given object

runMethod

public static Object runMethod(Object obj,
                               Method m,
                               String sParams)
                        throws CallerFailedException

Stolen from agentland.debug.MethodList Given a method to run with the String parameters parameter line, it will run the method on the agent specific to this MethodList. For parsing the params (which is most of the code), it uses commas as separators, trims the String of outer spaces, removes outer-most single/double quotes. For the class it must be (mapping the primitives to the corresponding object wrapper types), it searches for a constructor taking a single String, and it runs that with the input. "null" is translated as a null. The status bar is changed with the return value.

runMethod

public static Object runMethod(Object obj,
                               String method,
                               Object[] params)
                        throws CallerFailedException

getParamTypes

public static Class[] getParamTypes(Object[] params)

Given an array of objects, returns an array of types

runMethod

public static Object runMethod(Object obj,
                               Method m,
                               Object[] oParams)
                        throws CallerFailedException

Performs the actual call on the method and returns the result as an Object

Throws:

CallerFailedException - if an error occurs
