BytecodeReaderAndBinding

trait BytecodeReaderAndBinding 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.Instruction's.

The target array has the same size as the source array to make sure that branch offsets etc. point to the correct instruction.

    A DeferredActionsStore stores all functions that need to perform post load actions.

    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. This makes it possible to register functions that are newly created for a special class file object to perform actions related to that specific class file object.

    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.)

    pc

    The program counter of the invokedynamic instruction.

    DeferredDynamicConstantResolution
    Note

    This method is called (back) after the class file was completely loaded. Registration as a callback method happens whenever an ldc instruction 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 ldc instructions, 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.

    Resolves an org.opalj.br.instructions.INCOMPLETE_INVOKEDYNAMIC instruction using the BootstrapMethodTable of the class.

    invokeDynamicInfo

    The org.opalj.br.instructions.INVOKEDYNAMIC instruction's constant pool entry.

    instructions
