Class CLogViewEvent

class CLogViewEvent : public CLogView;

Description

A view on the event log.

The events included in the view are defined using a filter that specifies the constraints that all events in the view must satisfy. Filters are specified using one or more CLogFilter objects.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CActive - The core class of the active object abstraction.

• CLogActive - Common active object behaviour.

• CLogView - Navigates a view on the log database.

• CLogViewEvent - A view on the event log.

None required.

IMPORT_C TBool SetFilterL(const CLogFilterList &aFilterList, TRequestStatus &aStatus);

Description

Initialises or refreshes the event view defined by the set of specified filters.

The view can only be used after the request completes successfully.

Parameters

const CLogFilterList &aFilterList The set of filters. TRequestStatus &aStatus The request status. On request completion, contains:KErrNone, if the view has been successfully initialised or refreshed;one of the other system wide error codes, otherwise.

Return value

TBool ETrue, if the function has successfully issued the asynchronous request. EFalse, if there are no events in the view.

Capability:

Security policy note:

None required.
