Example 4 with Scope

use of net.sourceforge.pmd.lang.symboltable.Scope in project pmd by pmd.

the class ClassScope method determineArgumentTypes.

/**
 * Provide a list of types of the arguments of the given method call. The
 * types are simple type images. If the argument type cannot be determined
 * (e.g. because it is itself the result of a method call), the parameter
 * type is used - so it is assumed, it is of the correct type. This might
 * cause confusion when methods are overloaded.
 *
 * @param occurrence
 *            the method call
 * @param parameterTypes
 *            the parameter types of the called method
 * @return the list of argument types
