Direct Known Subclasses:

public abstract class VerificationTypeInfo
extends Object

VerificationTypeInfo structure, which is defined as a C-like union in the Java Virtual Machine Specification, section 4.8.4, and is used to define stack map frame structures. To map this union to Java classes, this class is abstract and has a separate public subclass for each union member. The verification type can be determined either by the its frame_type or using an instanceof test.

Nested Class Summary

static class	VerificationTypeInfo.DoubleVariableInfo A Double_variable_info type, which indicates that the location contains the verification type double.
static class	VerificationTypeInfo.FloatVariableInfo A Float_variable_info type, which indicates that the location contains the verification type float.
static class	VerificationTypeInfo.IntegerVariableInfo A Integer_variable_info type, which indicates that the location contains the verification type int.
static class	VerificationTypeInfo.LongVariableInfo A Long_variable_info type, which indicates that the location contains the verification type long.
static class	VerificationTypeInfo.NullVariableInfo A Null_variable_info type, which indicates that the location contains the verification type null.
static class	VerificationTypeInfo.ObjectVariableInfo An Object_variable_info type, which indicates that the location contains an instance of the class referenced by the constant pool entry.
static class	VerificationTypeInfo.TopVariableInfo A Top_variable_info type, which indicates that the local variable has the verification type top.
static class	VerificationTypeInfo.UninitializedThisVariableInfo A UninitializedThis_variable_info type, which indicates that the location contains the verification type uninitializedThis.
static class	VerificationTypeInfo.UninitializedVariableInfo An Uninitialized_variable_info type, which indicates that the location contains the verification type uninitialized(offset).

Method Detail

getTag

public int getTag()

Returns the structure's tag, which specifies its type. This tag is a value between 0 and 8, as defined by the ITEM_* constants in this class. (When Java 5 is the minimum JVM for NetBeans, these constants can be replaced with an enum.)
