Class GetMethodContext

java.lang.Object

com.ibm.wala.analysis.reflection.GetMethodContext

All Implemented Interfaces:

Context, ContextItem

public class GetMethodContext
extends Object
implements Context

A context which may be used if

• the method to be interpreted is either Class.getMethod(String, Class...) or Class.getDeclaredMethod(String, Class...),
• the type of the "this" argument is known and
• the value of the first argument (the method name) is a constant.

In the special case described above, GetMethodContextInterpreter and GetMethodContextSelector should be preferred over JavaLangClassContextInterpreter and JavaLangClassContextSelector, as GetMethodContextInterpreter and GetMethodContextSelector drastically reduce the number of methods returned increasing the precision of the analysis. Thus, GetMethodContextInterpreter and GetMethodContextSelector should be placed in be placed in front of JavaLangClassContextInterpreter and JavaLangClassContextSelector .

TODO Do the same for Class.getField(String) and Class.getDeclaredField(String).
