Member Function Documentation

void decaf::io::FileDescriptor::sync

(

)

Force any/all buffered data for this FileDescriptor to be flushed to the underlying device.

This method blocks until all data is flushed to the underlying device and is used to place the device into a known state. In the case of data that is buffered at a higher level such as a BufferedOutputStream the stream must first be flushed before this method can force the data to be sent to the output device.

bool decaf::io::FileDescriptor::valid

(

)

Indicates whether the File Descriptor is valid.

Returns

true for a valid descriptor such as open socket or file, false otherwise.

Field Documentation

long decaf::io::FileDescriptor::descriptor

protected

FileDescriptor decaf::io::FileDescriptor::err

static

A handle to the standard error stream.

Usually, this file descriptor is not used directly, but rather via the output stream known as System::err.

FileDescriptor decaf::io::FileDescriptor::in

static

A handle to the standard input stream.

Usually, this file descriptor is not used directly, but rather via the input stream known as System::in.

FileDescriptor decaf::io::FileDescriptor::out

static

A handle to the standard output stream.

Usually, this file descriptor is not used directly, but rather via the output stream known as System::out.
