Constructor & Destructor Documentation

StringStore::StringStore ( const char *  string = NULL)
inline

Construct a StringStore.

Parameters
stringpointer to a C-String

Definition at line 1160 of file filters.h.

Here is the call graph for this function:

StringStore::StringStore ( const byte string,
size_t  length 
)

Construct a StringStore.

Parameters
stringpointer to a memory buffer
lengthsize of the memory buffer

Member Function Documentation

size_t StringStore::CopyRangeTo2 ( BufferedTransformation target,
lword begin,
lword  end = LWORD_MAX,
const std::string &  channel = DEFAULT_CHANNEL,
bool  blocking = true 
) const
virtual

Copy bytes from this object to another BufferedTransformation.

Parameters
targetthe destination BufferedTransformation
beginthe 0-based index of the first byte to copy in the stream
endthe 0-based index of the last byte to copy in the stream
channelthe channel on which the transfer should occur
blockingspecifies whether the object should block when processing input
Returns
the number of bytes that remain in the copy block (i.e., bytes not copied)

CopyRangeTo2 copies bytes from this object to the destination. The bytes are not removed from this object. Copying begins at the index position in the current stream, and not from an absolute position in the stream.

begin is an IN and OUT parameter. When the call is made, begin is the starting position of the copy. When the call returns, begin is the position of the first byte that was not copied (which may be different tahn end). begin can be used for subsequent calls to CopyRangeTo2.

Implements BufferedTransformation.

Here is the call graph for this function:

size_t StringStore::TransferTo2 ( BufferedTransformation target,
lword byteCount,
const std::string &  channel = DEFAULT_CHANNEL,
bool  blocking = true 
)
virtual

Transfer bytes from this object to another BufferedTransformation.

Parameters
targetthe destination BufferedTransformation
byteCountthe number of bytes to transfer
channelthe channel on which the transfer should occur
blockingspecifies whether the object should block when processing input
Returns
the number of bytes that remain in the transfer block (i.e., bytes not transferred)

TransferTo() removes bytes from this object and moves them to the destination. Transfer begins at the index position in the current stream, and not from an absolute position in the stream.

byteCount is an IN and OUT parameter. When the call is made, byteCount is the requested size of the transfer. When the call returns, byteCount is the number of bytes that were transferred.
