/**
 * NOTE:  This class is currently not a fixed part of the API and may change in future releases.
 *
 * IR expression representing a method call, i.e. <code>foo.bar(baz)</code>.  If the root expression
 * is null, that means this is a static method call.  Flags on this class also indicate whether or not
 * this invocation should be compiled using INVOKEINTERFACE or INVOKESPECIAL rather than INVOKEVIRTUAL
 * in the case of an instance method invocation.
