Interface Variables

All Known Implementing Classes:

BytecodeGenProxyBuilder.VariableLoaderImpl

public interface Variables

A helper class for invoking BytecodeGenProxyBuilder proxy interfaces with arguments representing special values such as 'this' or a local variable. The numeric load methods load(Number, Runnable) and loadLocal(int, Type, Number) take an identifying value which should not collide with any other numeric values used when invoking a proxy method.

Modifier and Type	Method and Description
<O> O	load(java.lang.Class<O> clazz, java.lang.Runnable runnable)
<N extends java.lang.Number> N	load(N value, java.lang.Runnable runnable) Defers the loading of a numeric argument to runnable.
com.newrelic.agent.bridge.Transaction	loadCurrentTransaction() Returns a Transaction which loads the current transaction onto the stack.
<O> O	loadLocal(int localId, java.lang.Class<O> clazz) Returns an object that will load the local variable represented by the given id.
<N extends java.lang.Number> N	loadLocal(int local, org.objectweb.asm.Type type, N value)
java.lang.Object	loadThis(int access) Returns an object which represents 'this', which is null for a static method.

Method Detail
