Enum Class ClassFile.DeadLabelsOption

java.lang.Object
java.lang.Enum<ClassFile.DeadLabelsOption>
java.lang.classfile.ClassFile.DeadLabelsOption
All Implemented Interfaces:
Serializable, ClassFile.Option, Comparable<ClassFile.DeadLabelsOption>, Constable
Enclosing interface:
ClassFile

public static enum ClassFile.DeadLabelsOption extends Enum<ClassFile.DeadLabelsOption> implements ClassFile.Option
The option describing whether to filter unbound labels and drop their enclosing structures if possible. The default is FAIL_ON_DEAD_LABELS to fail fast with an IllegalArgumentException when a PseudoInstruction refers to an unbound label during bytecode generation.

The affected PseudoInstructions include ExceptionCatch, LocalVariable, LocalVariableType, and CharacterRange. Setting this option to DROP_DEAD_LABELS filters these pseudo-instructions from a CodeBuilder instead. Note that instructions, such as BranchInstruction, with unbound labels always fail-fast with an IllegalArgumentException.
