Detailed Description

String-based implementation of Store interface.

Definition at line 1155 of file filters.h.

Constructor & Destructor Documentation

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

inline

Construct a StringStore.

Parameters

string pointer 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
	)

inline

Construct a StringStore.

Parameters

string	pointer to a memory buffer
length	size of the memory buffer

Definition at line 1166 of file filters.h.

Here is the call graph for this function:

template<class T >

StringStore::StringStore ( const T & string )

inline

Construct a StringStore.

Template Parameters

T	std::basic_string<char> type

Parameters

string reference to a std::basic_string<char> type

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

target	the destination BufferedTransformation
begin	the 0-based index of the first byte to copy in the stream
end	the 0-based index of the last byte to copy in the stream
channel	the channel on which the transfer should occur
blocking	specifies 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.

void StringStore::StoreInitialize ( const NameValuePairs & parameters )

privatevirtual

Implements Store.

Definition at line 1088 of file filters.cpp.

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

target	the destination BufferedTransformation
byteCount	the number of bytes to transfer
channel	the channel on which the transfer should occur
blocking	specifies 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.
