FileInputStream() [1/2]

log4cxx::helpers::FileInputStream::FileInputStream

(

const LogString &

filename

)

Creates a FileInputStream by opening a connection to an actual file, the file named by the path name name in the file system.

Parameters

filename

The system-dependent file name.

FileInputStream() [2/2]

log4cxx::helpers::FileInputStream::FileInputStream

(

const File &

aFile

)

Creates a FileInputStream by opening a connection to an actual file, the file named by the File object file in the file system.

Parameters

aFile

The file to be opened for reading.

Member Function Documentation

read()

virtual int log4cxx::helpers::FileInputStream::read ( ByteBuffer &  buf )

virtual

Reads a sequence of bytes into the given buffer.

Parameters

buf	The buffer into which bytes are to be transferred.

Returns

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

Implements log4cxx::helpers::InputStream.
