CEComFilter Class Reference

class CEComFilter : public CBase

This class serves as the base class for ECom filter plugins. It provides minimal functionality to simply install and destroy filters specified by their UID or data type. The RHTTPSession passed in is passed onto the filter as a TAny* pointer and therefore must be casted back to an RHTTPSession pointer by the filter.

Intended Usage: Virtual destructor

Pre-condition: The object identified by the destructor key in iEcomDtorID exists

Post-condition: The object is destroyed

InstallFilterL(RHTTPSession, const TUid)

CEComFilter *	InstallFilterL	(	RHTTPSession	aSession,
			const TUid	aEComFilterUid
		)	[static, inline]

Intended Usage: This method is used to install filters to the filter queue. The implementation UID of the filter plugin is passed to identify the plugin that is required. The returned pointer is not owned as the filters must be self-destroying when they are unloaded.

Pre-condition: The session had already been setup

Post-condition: The filter(s) have been installed

Parameters

RHTTPSession aSession	A handle to the transport session
const TUid aEComFilterUid	The implementation UID of the plugin

InstallFilterL(RHTTPSession, const TDesC8 &)

CEComFilter *	InstallFilterL	(	RHTTPSession	aSession,
			const TDesC8 &	aEComFilterDataType
		)	[static, inline]

Pre-condition: The session had already been setup

Post-condition: The filter(s) have been installed

Parameters

RHTTPSession aSession	A handle to the transport session
const TDesC8 & aEComFilterDataType	A descriptor containing the datatype of the filter to load
