parseCpClass back to summary

private void parseCpClass(final InputStream in) throws IOException, Pack200Exception

Parses the constant pool class names, using cpClassCount to populate cpClass from cpUTF8.

Parameters

in:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec

parseCpDescriptor back to summary

private void parseCpDescriptor(final InputStream in) throws 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:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec

parseCpDouble	back to summary
private void parseCpDouble(final InputStream in) throws IOException, Pack200Exception

parseCpField back to summary

private void parseCpField(final InputStream in) throws IOException, Pack200Exception

Parses the constant pool field definitions, using cpFieldCount to populate cpFieldClass and cpFieldDescriptor.

Parameters

in:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec

parseCpFloat	back to summary
private void parseCpFloat(final InputStream in) throws IOException, Pack200Exception

parseCpIMethod back to summary

private void parseCpIMethod(final InputStream in) throws IOException, Pack200Exception

Parses the constant pool interface method definitions, using cpIMethodCount to populate cpIMethodClass and cpIMethodDescriptor.

Parameters

in:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec

parseCpInt	back to summary
private void parseCpInt(final InputStream in) throws IOException, Pack200Exception

parseCpLong	back to summary
private void parseCpLong(final InputStream in) throws IOException, Pack200Exception

parseCpMethod back to summary

private void parseCpMethod(final InputStream in) throws IOException, Pack200Exception

Parses the constant pool method definitions, using cpMethodCount to populate cpMethodClass and cpMethodDescriptor.

Parameters

in:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec

parseCpSignature back to summary

private void parseCpSignature(final InputStream in) throws 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:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec

parseCpString back to summary

private void parseCpString(final InputStream in) throws IOException, Pack200Exception

Parses the constant pool strings, using cpStringCount to populate cpString from indexes into cpUTF8.

Parameters

in:InputStream: the input stream to read from

Exceptions

IOException:: if a problem occurs during reading from the underlying stream
Pack200Exception:: if a problem occurs with an unexpected value or unsupported codec
