Methods of TIdIOHandler.

Method	Description
AfterAccept	Specifies the method used to initialize an IOHandler after a new connection request.
AllData	Retrieves all data from a connection.
Capture
CheckForDataOnSource	Determine if data is available in the unbuffered communication layer for the connection.
CheckForDisconnect	Checks state and status information on the transport for the IO handler.
Close	Closes the IO handler and associated Intercepts and transports.
CloseGracefully	Updates the ClosedGracefully property that indicates the connection has been closed by the peer.
Connected	Indicates the connection is open, or data exists in the Indy buffer.
InputBufferAsString	Provides access to the contents of the Indy input buffer in string form.
InputBufferIsEmpty	Indicates the input buffer for the IOHandler does not contain any data.
InputBufferToStream	Stores the contents of the input buffer to a stream.
InputLn	Reads a line of data from the connection.
MakeDefaultIOHandler	Creates an instance of the IOHandler using the default class factory.
MakeIOHandler	Creates a new instance of an IOHandler using the specified class reference.
Open	Prepares the IOHandler for subsequent read and write requests.
Readable	Indicates if the IOHandler is ready to perform a read request.
ReadBytes	Perform a read request for IOHandler.
ReadCardinal	Reads the ordinal data type from the IOHandler connection.
ReadChar	Reads the simple data type from the IOHandler connection.
ReadInt64	Reads a 64-bit Integer data type from the data source for the IOHandler.
ReadInteger	Reads the data type from the IOHandler connection.
ReadLn
ReadLnSplit	Reads a line from the Indy buffer.
ReadLnWait	Waits for a line of text to be read from the IOHandler.
ReadSmallInt	Reads the data type from the IOHandler connection.
ReadStream	Reads data from the IOHandler into a stream.
ReadString	Reads a Delphi string from the IOHandler buffer.
ReadStrings	Reads one or more lines of text from the IOHandler into a TIdStrings instance.
RegisterIOHandler	Guaranteess that the IOHandler class exists in the registered IOHandler class list.
SetDefaultClass
WaitFor	Searches for a specific value in the input received from the data source for the IOHandler.
Write
WriteBufferCancel	Clears and cancels write buffering for the IOHandler.
WriteBufferClear	Discards any exisitng data in the write buffering mechanism.
WriteBufferClose	Disables uses write buffering for the IOHandler connection.
WriteBufferFlush
WriteBufferingActive	Indicates if write buffering is enabled for the IOHandler.
WriteBufferOpen
WriteDirect	Moves values to the socket-level transport for the IOHandler.
WriteFile	Writes the contents of a local file to the IOHandler.
WriteLn	Writes a string value to IOHandler.
WriteRFCStrings	Writes a list of RFC-compatible strings to the peer for the IOHandler class instance.

Destructors
