class IOHandlerImpl : public AbstractIOHandlerImpl

This class wraps a file descriptor and provides methods to get information about the descriptor and to read and write from the descriptor

Inheritance:

Public Methods

	IOHandlerImpl (int fd) Constructs this object
	~IOHandlerImpl () Destroys this object
int	getDescriptor () const Gets the descriptor
bool	isOpen () const Determines if the descriptor is open
bool	isClosed () const To check if the file descriptor is closed
int	read (char* buf, int num) To read from the descriptor, a specified number of bytes into buffer
int	write (const char* buf, int num) To write to the descriptor, a specified number of bytes from the buffer
int	close () Closes the descriptor
string	paramString () const Returns a string representation for IOHandler which is used debugging purposes

Inherited from AbstractIOHandlerImpl:

IOHandlerImpl(int fd)

Constructs this object.

Parameters:

fd - the file descriptor

~IOHandlerImpl()

Destroys this object

int getDescriptor() const

Gets the descriptor.

Returns:

the descriptor

bool isOpen() const

Determines if the descriptor is open

Returns:

an indication if descriptor is open or not

bool isClosed() const

To check if the file descriptor is closed.

Returns:

indicates that the file descriptor is closed

int read(char* buf, int num)

To read from the descriptor, a specified number of bytes into buffer.

Returns:

the actual bytes being read

Parameters:

buf - the buffer to read into
num - specified number of bytes

int write(const char* buf, int num)

To write to the descriptor, a specified number of bytes from the buffer.

Returns:

the actual bytes being written

Parameters:

buf - the buffer to write from
num - specified number of bytes to write

int close()

Closes the descriptor.

Returns:

status after being closed

string paramString() const

Returns a string representation for IOHandler which is used debugging purposes.

Returns:

debugging info
