    In this representation of Java bytecode references to a Java class file's constant pool and to attributes are replaced by direct references to the corresponding constant pool entries.

    In this representation of Java bytecode references to a Java class file's constant pool and to attributes are replaced by direct references to the corresponding constant pool entries. This facilitates developing analyses and fosters comprehension.

    Based on the fact that indirect references to constant pool entries are resolved and replaced by direct references this representation is called the resolved representation.

    This representation of Java bytecode is considered as OPAL's standard representation for writing Scala based analyses. This representation is engineered such that it facilitates writing analyses that use pattern matching.

BasicBlock

class BasicBlock extends CFGNode

Represents a basic block of a method's control flow graph (CFG). The basic block is identified by referring to the first and last instruction belonging to the basic block.

    Returns the index of an instruction – identified by its program counter (pc) – in a basic block.

    Example

    Given a basic block which has five instructions which have the following program counters: {0,1,3,5,6}. In this case the index of the instruction with program counter 3 will be 2 and in case of the instruction with pc 6 the index will be 4.

    pc

    The program counter of the instruction for which the index is needed. pc has to satisfy: startPC <= pc <= endPC.

    code

    The code to which this basic block belongs.
