Destructor

Member Function Documentation

virtual void abnormalDialogInfo ( NamedList & params ) [virtual]

Set information in case of abnormal dialog detection

Parameters:

params List of parameters where to set the abnormal dialog information

Reimplemented from SS7TCAPTransaction.

SS7TCAPError decodeDialogPortion	(	NamedList &	params,
		DataBlock &	data
	)		`[virtual]`

Decode dialog portion

Parameters:

params	List into which to put the decoded dialog parameters
data	Data to decodeCaps

Returns:: A report error

Implements SS7TCAPTransaction.

static SS7TCAPError decodePAbort	(	SS7TCAPTransaction *	tr,
		NamedList &	params,
		DataBlock &	data
	)		`[static]`

Decode P-Abort TCAP message portion

Parameters:

tr	The transaction on which the abort was signalled
params	NamedList reference to fill with the decoded P-Abort information
data	DataBlock reference from which to decode P-Abort information

Returns:: A report error

bool dialogPresent ( ) [inline]

Check if the transaction present dialog information

Returns:: True if dialog information is present, false otherwise

void encodeDialogPortion	(	NamedList &	params,
		DataBlock &	data
	)		`[virtual]`

Encode dialog portion of transaction

Parameters:

params	List of parameters to encode
data	Data block into which to insert the encoded data

Implements SS7TCAPTransaction.

static void encodePAbort	(	SS7TCAPTransaction *	tr,
		NamedList &	params,
		DataBlock &	data
	)		`[static]`

Encode P-Abort information

Parameters:

tr	The transaction on which the abort was signalled
params	NamedList reference from which to get the P-Abort information
data	DataBlock reference in which to insert the encoded P-Abort information

virtual SS7TCAPError handleData	(	NamedList &	params,
		DataBlock &	data
	)		`[virtual]`

Process transaction data and fill the NamedList with the decoded data

Parameters:

params	NamedList to fill with decoded data
data	Data to decode

Returns:: A TCAP error encountered whilst decoding

Implements SS7TCAPTransaction.

virtual SS7TCAPError handleDialogPortion	(	NamedList &	params,
		bool	byUser = `true`
	)		`[virtual]`

Handle TCAP relevant dialog data

Parameters:

params	NamedList containing (if present) dialog information
byUser	True if the dialog information is provided by the local user, false otherwise

Returns:: A report error

Implements SS7TCAPTransaction.

virtual void requestContent	(	NamedList &	params,
		DataBlock &	data
	)		`[virtual]`

Request content for this transaction

Parameters:

params	List of parameters of this tranaction
data	Data block to fill with encoded content

Implements SS7TCAPTransaction.

bool testForDialog ( DataBlock & data )

Test for dialog when decoding

Parameters:

data	Data from which the transaction is decoded

Returns:: True if dialog portion is present, false otherwise

virtual SS7TCAPError update	(	SS7TCAP::TCAPUserTransActions	type,
		NamedList &	params,
		bool	updateByUser = `true`
	)		`[virtual]`

An update request for this transaction

Parameters:

type	The type of transaction to which this transaction should be updated
params	Update parameter
updateByUser	True if the update is made by the local user, false if it's made by the remote end
