Interface StackMapTableAttribute

All Superinterfaces:

Attribute<StackMapTableAttribute>, ClassFileElement, CodeElement

public sealed interface StackMapTableAttribute
extends Attribute<StackMapTableAttribute>, CodeElement

Models the StackMapTable attribute (JVMS 4.7.4), which is used for verification by type checking (4.10.1).

This attribute is not delivered in the traversal of a CodeAttribute, but instead automatically generated upon class file writing. Advanced users can supply their own stack maps according to the ClassFile.StackMapsOption.

This attribute only appears on Code attributes, and does not permit multiple instances in a Code attribute. It has a data dependency on labels in the code array.

This attribute was introduced in the Java SE Platform version 6, major version 50.
