Class InitMethodStrategy

java.lang.Object
  extended by com.tc.object.bytecode.rwsync.InitMethodStrategy
All Implemented Interfaces:
MethodStrategy

public class InitMethodStrategy
extends java.lang.Object
implements MethodStrategy

A strategy to process constructors of classes containing locking fields. In general the class adapter of such a class will extend LockingClassAdapter, and will declare a map of MethodId to MethodStrategy. Such class adapters must call LockingClassAdapter.addLockFields() to add the fields to the class, and must map constructor methods to this strategy.

                                 java.lang.String outerType,

Description copied from interface: MethodStrategy
Instrument a method, possibly creating other methods in the process. A do-nothing implementation might look like:
   visitMethod(...) {
     return cv.visitMethod(access, name, desc, signature, exceptions);
   }
 
This would delegate the visitMethod() call to the next class adapter in the chain, returning a method visitor which could then be visited with the method's contents.

Specified by:
visitMethod in interface MethodStrategy
Parameters:
cv - a way of calling the next class adapter in the chain. Do not pass in the samed ClassVisitor that is invoking the method strategy, or you'll recurse endlessly! Note that cv.visitMethod may be called more than once during a single call to this method, and must return a distinct MethodVisitor instance for each call.
ownerType - the internal type name of the class that contains the method, e.g., "org/xyz/Foo$Bar"
outerType - null if ownerType is a top-level type, or else the internal type name of its outer class e.g. "org/xyz/Foo"
outerDesc - null if ownerType is a top-level type, or else the type descriptor of its outer class, e.g. "Lorg/xyz/Foo;"
Returns:
a method visitor which can be called with the contents of the original method. Implementations must not return null, but may return a visitor that ignores all calls.
