Interface LabelTarget

All Superinterfaces:
ClassFileElement, CodeElement, PseudoInstruction
public sealed interface LabelTarget extends PseudoInstruction
A pseudo-instruction which indicates that the specified label corresponds to the current position in the Code attribute. Delivered as a CodeElement during traversal of the elements of a CodeModel.

This can be used to inspect the target position of labels across transformations, as bci is not stable.

When passed to a CodeBuilder, this pseudo-instruction sets the specified label to be bound at the current position in the builder.

By design, LabelTarget cannot be created by users and can only be read from a code model. Use CodeBuilder::labelBinding to bind arbitrary labels to a CodeBuilder.

For a CodeBuilder cob, a LabelTarget lt, these two calls are equivalent: 

cob.with(lt);
cob.labelBinding(lt.label());
