Class InternalTypeEnumeration

  • All Implemented Interfaces:
    java.util.Iterator<java.lang.String>
    public class InternalTypeEnumeration
extends java.lang.Object
implements java.util.Iterator<java.lang.String>
    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.

      • hasNext

        public boolean hasNext()
        Specified by:
        hasNext in interface java.util.Iterator<java.lang.String>

      • next

        public java.lang.String next()
        Specified by:
        next in interface java.util.Iterator<java.lang.String>
