Interface BranchInstruction
- All Superinterfaces:
- ClassFileElement,- CodeElement,- Instruction
Models a branching instruction (conditional or unconditional) in the 
 
 code array of a Code attribute.  Corresponding opcodes have a
 kind of Opcode.Kind.BRANCH.  Delivered as
 a CodeElement when traversing the elements of a CodeModel.
 A branch instruction is composite:
BranchInstruction(
    Opcode opcode,
    Label target
)
 Due to physical restrictions, some types of instructions cannot encode labels
 too far away in the list of code elements.  In such cases, the ClassFile.ShortJumpsOption controls how an invalid branch instruction model
 is written by a CodeBuilder.
