Member Function Documentation

wxSQLite3Blob & wxSQLite3Blob::operator=

(

const wxSQLite3Blob &

blob

)

Assignement constructor.

wxMemoryBuffer & wxSQLite3Blob::Read	(	wxMemoryBuffer &	blobValue,
		int	length,
		int	offset
	)

Read partial BLOB value.

Parameters:

	blobValue	memory buffer receiving the partial content of the BLOB
	length	length of BLOB content to be read
	offset	offset within BLOB where the read starts

Returns:

the address of the memory buffer

void wxSQLite3Blob::Write	(	const wxMemoryBuffer &	blobValue,
		int	offset
	)

Write partial BLOB value.

Parameters:

	blobValue	memory buffer receiving the partial content of the BLOB
	offset	offset within BLOB where the read starts

bool wxSQLite3Blob::IsOk

(

)

Check whether the BLOB handle is correctly initialized.

Returns:

TRUE if the BLOB handle is correctly initialized, FALSE otherweis

bool wxSQLite3Blob::IsReadOnly

(

)

Check whether the BLOB handle is read only.

Returns:

TRUE if the BLOB handle is readonly, FALSE otherweis

int wxSQLite3Blob::GetSize

(

)

Get the size of the associated BLOB.

Returns:

the BLOB size

void wxSQLite3Blob::Finalize

(

)

Finalize the BLOB.
