Bfile Class close() closeStream() Table 8–2 Bfile Methods (Cont.) Method Summary fileExists() on page 8-7 Test whether the BFILE exists. getDirAlias() on page 8-7 Return the directory alias of the BFILE. getFileName() on page 8-7 Return the name of the BFILE. getStream() on page 8-7 Return data from the BFILE as a Stream object. isInitialized() on page 8-8 Test whether the Bfile object is initialized. isNull() on page 8-8 Test whether the Bfile object is atomically null. isOpen() on page 8-8 Test whether the BFILE is open. length() on page 8-9 Return the number of bytes in the BFILE. open() on page 8-9 Open the BFILE with read-only access. operator=() on page 8-9 Assign a BFILE locator to the Bfile object. operator==() on page 8-9 Test whether two Bfile objects are equal. operator!=() on page 8-10 Test whether two Bfile objects are not equal. read() on page 8-10 Read a specified portion of the BFILE into a buffer. setName() on page 8-11 Set the directory alias and file name of the BFILE. setNull() on page 8-11 Set the Bfile object to atomically null. This method closes a previously opened BFILE. Syntax void close(); This method closes the stream obtained from the BFILE. Syntax void closeStream(Stream *stream); 8-6 Oracle C++ Call Interface Programmer’s Guide
fileExists() getDirAlias() getFileName() getStream() Parameters stream The stream to be closed. This method tests whether the BFILE exists. If the BFILE exists, then true is returned; otherwise, false is returned. Syntax bool fileExists() const; This method returns a string containing the directory alias associated with the BFILE. Syntax string getDirAlias() const; Bfile Class This method returns a string containing the file name associated with the BFILE. Syntax string getFileName() const; This method returns a Stream object read from the BFILE. If a stream is already open, it is disallowed to open another stream on the Bfile object. The stream must be closed before performing any Bfile object operations. Syntax Stream* getStream(unsigned int offset = 1, unsigned int amount = 0); OCCI Classes and Methods 8-7
