Constructor & Destructor Documentation

tntdb::Blob::Blob	(	const char *	data,
		std::size_t	len
	)			[inline]

Construct a Blob with data of a given length.

Constructs a Blob using a default implementation using new/delete to manage the blob-data and the shared data object. The first len bytes of the data pointed to by data are copied to this Blob.

tntdb::Blob::Blob

(

IBlob *

b

)

[inline, explicit]

Construct a Blob to use a customized implementation.

Member Function Documentation

void tntdb::Blob::assign	(	const char *	data,
		std::size_t	len
	)			[inline]

assigns the data to this blob object

const char* tntdb::Blob::data

(

)

const [inline]

Returns a pointer to the data or 0 if no data is set.

char* tntdb::Blob::reserve	(	std::size_t	len,
		bool	shrink = false
	)			[inline]

makes sure, the buffer it at least len bytes.

If shrink is set, the buffer will be exactly len bytes. Data is not preserved when reallocated.

std::size_t tntdb::Blob::size

(

)

const [inline]

Returns the size of the data.
