Constructor Details

ExitAdviceByteCodeAppender

protected ExitAdviceByteCodeAppender(int load,
 int store,
 int convert,
 int branch,
 int size)

Creates a byte code appender for exit advice on a cached return plugin.

Parameters:

load - The byte code that loads a value onto the stack from the local variable array.

store - The byte code that stores a value to the local variable array.

convert - An instruction to convert the cached value to a value that is applied on the branch instruction.

branch - A jump instruction that checks if the cached value is already set.

size - The size of the created type on the operand stack.

Method Details

apply

public ByteCodeAppender.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
 Implementation.Context implementationContext,
 MethodDescription instrumentedMethod)

Applies this byte code appender to a type creation process.

Specified by:

apply in interface ByteCodeAppender

Parameters:

methodVisitor - The method visitor to which the byte code appender writes its code to.

implementationContext - The implementation context of the current type creation process.

instrumentedMethod - The method that is the target of the instrumentation.
