Nested Class Summary

static interface

FieldReader.IFieldReaderTask A visitor that is invoked for every component spec found during the header parsing of the FieldReader#readIWFFieldSpecs(byte[], int, int, int, int, IFieldReaderTask) and FieldReader#readSWFFieldSpecs(byte[], int, int, int, int, IFieldReaderTask) methods.

Constructor Summary

FieldReader()

Method Summary

static void	readIWFFieldSpecs(IOperationScope scope, byte[] buffer, int headerStart, int headerLen, int dataStart, int dataLen, FieldReader.IFieldReaderTask task) Parses the buffer from headerStart to headerLen and for each component spec found, invokes the component reader task to process the component.
static void	readSWFFieldSpecs(IOperationScope scope, byte[] buffer, int headerStart, int headerLen, int dataStart, int dataLen, FieldReader.IFieldReaderTask task) Parses the buffer from headerStart to headerLen and for each component spec found, invokes the component reader task to process the component.

readSWFFieldSpecs

public static void readSWFFieldSpecs(IOperationScope scope,
                                     byte[] buffer,
                                     int headerStart,
                                     int headerLen,
                                     int dataStart,
                                     int dataLen,
                                     FieldReader.IFieldReaderTask task)

Parses the buffer from headerStart to headerLen and for each component spec found, invokes the component reader task to process the component. This method operates on string wire format component specs.

Parameters:

scope - the scope of the read state operation

buffer - the byte[] holding the header and data buffers, at some location

headerStart - the position in the buffer where the header buffer is located

headerLen - the number of bytes that make up the header buffer

dataStart - the position in the buffer where the data buffer is located

dataLen - the number of bytes that make up the data buffer

task - the delegate task that will process each component spec found

readIWFFieldSpecs

public static void readIWFFieldSpecs(IOperationScope scope,
                                     byte[] buffer,
                                     int headerStart,
                                     int headerLen,
                                     int dataStart,
                                     int dataLen,
                                     FieldReader.IFieldReaderTask task)

Parses the buffer from headerStart to headerLen and for each component spec found, invokes the component reader task to process the component. This method operates on integer wire format component specs.

Parameters:

scope - the scope of the read state operation

buffer - the byte[] holding the header and data buffers, at some location

headerStart - the position in the buffer where the header buffer is located

headerLen - the number of bytes that make up the header buffer

dataStart - the position in the buffer where the data buffer is located

dataLen - the number of bytes that make up the data buffer

task - the delegate task that will process each component spec found
