trait CachedBytecodeReaderAndBinding extends InstructionsDeserializer
Defines a method to parse an array of bytes (containing Java bytecode instructions) and
to return an array of org.opalj.br.instructions.Instructions.
The target array has the same size as the source array to make sure that branch offsets etc. point to the correct instruction.
This reader caches the instructions – primarily – to save memory once all class files are loaded.

A DeferredActionsStore stores all functions that need to perform post load actions.
One example is the resolution of references to attributes. (The constant pool is the only structure that is passed around and hence it is the only place where to store information/functions related to a specific class file).

Creates a storage area for functions that will be called after the class file was completely loaded.

Resolves an org.opalj.br.instructions.INCOMPLETE_LDC instruction using the BootstrapMethodTable of the class.
Resolves an org.opalj.br.instructions.INCOMPLETE_LDC instruction using the BootstrapMethodTable of the class.
Deferred resolution is necessary since the BootstrapMethodTable – which is an attribute of the class file – is loaded after the methods.
- classFile
The ClassFile with which the deferred action was registered.
- cp
The class file's Constant_Pool.
- dynamicInfo
The consttant pool entry describing the dynamic constant.
- instructions
This method's array of instructions.Instructions. (The array returned by the #Instructions method.)

invokedynamicinstruction.

- Note
This method is called (back) after the class file was completely loaded. Registration as a callback method happens whenever an
ldcinstruction is found in a method's byte code that refers to a dynamic constant.Overriding this Method
To perform additional analyses on dynamic constant loading
ldcinstructions, e.g., to fully resolve the constant, a subclass may override this method to do so. When you override this method, you should call this method (super.deferredResolveDynamicConstantResolution) to ensure that the default resolution is carried out.
