Models a dynamically-computed call site invocation instruction in the code array of a Code attribute. The corresponding opcode is invokedynamic. Delivered as a CodeElement when traversing the elements of a CodeModel.

A dynamically-computed call site invocation instruction is composite:

InvokeDynamicInstruction(InvokeDynamicEntry invokedynamic) 
InvokeDynamicInstruction(InvokeDynamicEntry invokedynamic)
