        private void parseCpClass​(java.io.InputStream in)
                   throws java.io.IOException,
                          Pack200Exception
        Parses the constant pool class names, using #cpClassCount to populate cpClass from cpUTF8.
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec

      • parseCpDescriptor

        private void parseCpDescriptor​(java.io.InputStream in)
                        throws java.io.IOException,
                               Pack200Exception
        Parses the constant pool descriptor definitions, using #cpDescriptorCount to populate cpDescriptor. For ease of use, the cpDescriptor is stored as a string of the form name:type, largely to make it easier for representing field and method descriptors (e.g. out:java.lang.PrintStream) in a way that is compatible with passing String arrays.
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec

      • parseCpDouble

        private void parseCpDouble​(java.io.InputStream in)
                    throws java.io.IOException,
                           Pack200Exception
        Throws:
        java.io.IOException
        Pack200Exception

      • parseCpField

        private void parseCpField​(java.io.InputStream in)
                   throws java.io.IOException,
                          Pack200Exception
        Parses the constant pool field definitions, using #cpFieldCount to populate cpFieldClass and cpFieldDescriptor.
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec

      • parseCpFloat

        private void parseCpFloat​(java.io.InputStream in)
                   throws java.io.IOException,
                          Pack200Exception
        Throws:
        java.io.IOException
        Pack200Exception

      • parseCpIMethod

        private void parseCpIMethod​(java.io.InputStream in)
                     throws java.io.IOException,
                            Pack200Exception
        Parses the constant pool interface method definitions, using #cpIMethodCount to populate cpIMethodClass and cpIMethodDescriptor.
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec

      • parseCpMethod

        private void parseCpMethod​(java.io.InputStream in)
                    throws java.io.IOException,
                           Pack200Exception
        Parses the constant pool method definitions, using #cpMethodCount to populate cpMethodClass and cpMethodDescriptor.
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec

      • parseCpSignature

        private void parseCpSignature​(java.io.InputStream in)
                       throws java.io.IOException,
                              Pack200Exception
        Parses the constant pool signature classes, using #cpSignatureCount to populate cpSignature. A signature form is akin to the bytecode representation of a class; Z for boolean, I for int, [ for array etc. However, although classes are started with L, the class name does not follow the form; instead, there is a separate array of classes. So an array corresponding to public static void main(String args[]) has a form of [L(V) and a classes array of [java.lang.String]. The cpSignature is a string representation identical to the bytecode equivalent [Ljava/lang/String;(V) TODO Check that the form is as above and update other types e.g. J
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec

      • parseCpString

        private void parseCpString​(java.io.InputStream in)
                    throws java.io.IOException,
                           Pack200Exception
        Parses the constant pool strings, using #cpStringCount to populate cpString from indexes into cpUTF8.
        Parameters:
        in - the input stream to read from
        Throws:
        java.io.IOException - if a problem occurs during reading from the underlying stream
        Pack200Exception - if a problem occurs with an unexpected value or unsupported codec
