Detailed Description

Provide session context of component.

The session contexts has one parent and they build a tree, where the root of this tree describes main component of framework. Session context provides individual set of attributes generated from icomp::IRegistryElement objects. For static components each component instance has own context object. For dynamic components all components using the same factory have the same session context instance.

◆ GetAttribute()

virtual const iser::IObject * icomp::IComponentContext::GetAttribute	(	const QByteArray &	attributeId,
		int *	definitionLevelPtr = `NULL`
	)		const

pure virtual

Get attribute using its ID.

Parameters

attributeId	ID of attribute.
definitionLevelPtr	optional return value. This will be set to number parents you have to iterate to get component where this attribute was defined. If this attribute was defined in actual component it equals 0.

Implemented in icomp::CComponentContext, and icomp::CSimComponentContextBase.
