Detailed Description

InputStream implemented on top of APR file IO.

Constructor & Destructor Documentation

FileInputStream() [1/3]

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() [2/3]

log4cxx::helpers::FileInputStream::FileInputStream

(

const logchar *

filename

)

FileInputStream() [3/3]

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.

~FileInputStream()

virtual log4cxx::helpers::FileInputStream::~FileInputStream ( )

virtual

Member Function Documentation

close()

void log4cxx::helpers::FileInputStream::close ( )

overridevirtual

Closes this file input stream and releases any system resources associated with the stream.

Implements log4cxx::helpers::InputStream.

read()

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

overridevirtual

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.
