    • getTypeDescriptor

      public abstract HierarchicalTypeSignature getTypeDescriptor()
      Returns the parsed type descriptor for the class member, which will not include type parameters. If you need generic type parameters, call getTypeSignature() instead.
      Returns:
      The parsed type descriptor string for the class member.

    • getTypeDescriptorStr

      public String getTypeDescriptorStr()
      Returns the type descriptor string for the class member, which will not include type parameters. If you need generic type parameters, call getTypeSignatureStr() instead.

      The type descriptor string for the class member.

    • getTypeSignature

      public abstract HierarchicalTypeSignature getTypeSignature()
      Returns the parsed type signature for the class member, possibly including type parameters. If this returns null, that no type signature information is available for this class member, call getTypeDescriptor() instead.
      Returns:
      The parsed type signature for the class member, or null if not available.
      Throws:
      IllegalArgumentException - if the class member type signature cannot be parsed (this should only be thrown in the case of classfile corruption, or a compiler bug that causes an invalid type signature to be written to the classfile).

    • getTypeSignatureStr

      public String getTypeSignatureStr()
      Returns the type signature string for the class member, possibly including type parameters. If this returns null, indicating that no type signature information is available for this class member, call getTypeDescriptorStr() instead.
      Returns:
      The type signature string for the class member, or null if not available.

    • getTypeSignatureOrTypeDescriptor

      public abstract HierarchicalTypeSignature getTypeSignatureOrTypeDescriptor()
      Returns the type signature for the class member, possibly including type parameters. If the type signature is null, indicating that no type signature information is available for this class member, returns the type descriptor instead.
      Returns:
      The parsed type signature for the class member, or if not available, the parsed type descriptor for the class member.

    • getTypeSignatureOrTypeDescriptorStr

      public String getTypeSignatureOrTypeDescriptorStr()
      Returns the type signature string for the class member, possibly including type parameters. If the type signature string is null, indicating that no type signature information is available for this class member, returns the type descriptor string instead.
      Returns:
      The type signature string for the class member, or if not available, the type descriptor string for the class member.
