Interface LocalVariableTypeTableAttribute

All Superinterfaces:: Attribute<LocalVariableTypeTableAttribute>, ClassFileElement

public sealed interface LocalVariableTypeTableAttribute extends Attribute<LocalVariableTypeTableAttribute>

Models the LocalVariableTypeTable attribute (JVMS 4.7.14), which records debug information about local variables with generic types. Its entries are delivered as LocalVariableTypes when traversing the elements of a CodeModel, which can be toggled by ClassFile.DebugElementsOption.

This attribute only appears on Code attributes, and permits multiple instances in a Code attribute. It has a data dependency on labels.

This attribute cannot be sent to a CodeBuilder; its entries can be constructed with LocalVariableType, resulting in at most one attribute instance in the built Code attribute.

The attribute was introduced in the Java SE Platform version 5.0, major version 49.

API Note:

Only local variables that have generic field types need to be described by this attribute. If a local variable is described in a


LocalVariableTypeTable

attribute, it must also be described in a LocalVariableTable attribute.
