Detailed Description

 FinderTcpBase (EventLoop& e, int fd)

FinderTcpBase

 ~FinderTcpBase ()

~FinderTcpBase

[virtual]

void  read_event (int errval, const uint8_t* data, uint32_t data_bytes)

read_event

[pure virtual]

Method to be implemented by derived classes that is called when data arrives or an error occurs when processing when data arrives.

Parameters:
errvalerror code, values are equivalent to errno.
datapointer to data
data_bytessize of data.

void  set_read_enabled (bool en)

set_read_enabled

Control whether read events can occur.

Parameters:
enboolean value with true corresponding to read enabled.

bool  read_enabled ()

read_enabled

[const]

Determine whether read events can occur.

Returns: true if read events are enabled.

bool  write_data (const uint8_t* data, uint32_t data_bytes)

write_data

Write data on TCP connection. To avoid an unnecessary data copy, the client is expected to ensure the data is valid until departure_event is called with the corresponding data pointer.

Parameters:
datapointer to data.
data_bytessize data pointed to in bytes.

Returns: true if data accepted for writing, false if no buffer space is available at this time.

bool  write_data (const iovec* iov, uint32_t iovcnt)

write_data

void  write_event (int errval, const uint8_t* data, uint32_t data_bytes)

write_event

[pure virtual]

Method to be implemented by derived classes that is called when data writing completes or an error occurs when processing when write.

Parameters:
errvalerror code, values are equivalent to errno.

void  close_event ()

close_event

[virtual]

Method that may be implemented by derived classes for detecting when the underlying socket is closed.

void  error_event ()

error_event

[virtual]

void  close ()

close

bool  closed ()

closed
