Class InternalTypeEnumeration

java.lang.Object

proguard.classfile.util.InternalTypeEnumeration

public class InternalTypeEnumeration
extends java.lang.Object

An InternalTypeEnumeration provides an enumeration of all types listed in a given internal descriptor or signature of a class, a method, or a field.

The leading formal type parameters, if any, can be retrieved separately.

The return type of a method descriptor can also be retrieved separately.

Constructor Detail

InternalTypeEnumeration

public InternalTypeEnumeration(java.lang.String descriptor)

Creates a new InternalTypeEnumeration for the given method descriptor.

Method Detail

typeCount

public int typeCount()

Returns the number of types contained in the descriptor. This is the number of types that the enumeration will return.

typesSize

public int typesSize()

Returns the total size of the types contained in the descriptor. This accounts for long and double parameters taking up two entries.

hasFormalTypeParameters

public boolean hasFormalTypeParameters()

Returns whether the descriptor has leading formal type parameters.

formalTypeParameters

public java.lang.String formalTypeParameters()

Returns the leading formal type parameters from the descriptor.

isMethodSignature

public boolean isMethodSignature()

Returns whether the descriptor is a method signature.

hasMoreTypes

public boolean hasMoreTypes()

Returns whether the enumeration can provide more types from the method descriptor.

nextType

public java.lang.String nextType()

Returns the next type from the method descriptor.

returnType

public java.lang.String returnType()

Returns the return type from the descriptor, assuming it's a method descriptor.

main

public static void main(java.lang.String[] args)

A main method for testing the type enumeration.
