Constructor & Destructor Documentation

LATdataBufferIterator::LATdataBufferIterator (  LATcomponentIterator *  lci, bool  swap = !DFC_BIG_ENDIAN )  [inline]

LATdataBufferIterator constructor. LATdataBufferIterator is a convenience class to allow simple invocation of iterators to parse data in supplied string buffers. This class provides applications access only to LATcontributions that are EBFevents, but not to unrecognized LATcontributions. A LATcomponentIterator instance is required to provide the virtual method resolution needed to handle subsystem data. A swapping option is provided to allow byte swapping of the buffer prior to iteratation, if needed. Parameters: lci  - A pointer to a LATcomponentIterator instance swap  - Optional parameter indicating whether buffers should be byteswapped prior to being iterated over. The default value is True if the machine this code is running is not big endian and False otherwise.

LATdataBufferIterator::LATdataBufferIterator (  LDBI_LATcontributionIterator *  lci, bool  swap = !DFC_BIG_ENDIAN )  [inline]

LATdataBufferIterator constructor. LATdataBufferIterator is a convenience class to allow simple invocation of iterators to parse data in supplied string buffers. This class provides applications access to LATcontributions, both EBFevents and others. A LDBI_LATcontributionIterator instance is required to provide the virtual method resolution needed to handle subsystem data. A swapping option is provided to allow byte swapping of the buffer prior to iteratation, if needed. Parameters: lci  - A pointer to a LDBI_LATcontributionIterator instance swap  - Optional parameter indicating whether buffers should be byteswapped prior to being iterated over. The default value is True if the machine this code is running is not big endian and False otherwise.

Member Function Documentation

int LATdataBufferIterator::iterate (  char *  buffer, unsigned  length, bool  swap )  [inline]

Iterate over a given buffer of specified length. Byteswap by longwords in place if requested. This method iterates over the datagrams in a string buffer of specified length, after possibly bytswapping the buffer by longwords in place first. Use this method to override the constructor swap argument. This allows iterating over the same buffer multiple times without swapping it each time. Parameters: buffer  A string buffer containing LATdatagrams length  The length of the supplied string buffer swap  Forces the supplied buffer to be byteswapped in place, or not Returns: The result from iterating over the datagrams in the buffer

int LATdataBufferIterator::iterate (  char *  buffer, unsigned  length )  [inline]

Iterate over a given buffer of specified length. Byteswap by longwords in place according to the constructor swap value. This method iterates over the datagrams in a string buffer of specified length, after possibly bytswapping the buffer by longwords in place first. Parameters: buffer  A string buffer containing LATdatagrams length  The length of the supplied string buffer Returns: The result from iterating over the datagrams in the buffer

int LATdataBufferIterator::iterate (   )  [inline]

Reiterate over a buffer that has already been iterated over by LATdataBufferIterator::iterate(char* buffer, unsigned length). Returns: The result from iterating over the datagrams in the buffer
