virtual EQFABRIC_INL void eq::fabric::View< L, V, O >::serialize	(	co::DataOStream &	,
		const uint64_t
	)		`[protected, virtual]`

Worker for pack() and getInstanceData().

Override this and deserialize() if you want to distribute subclassed data.

This method is called with DIRTY_ALL from getInstanceData() and with the actual dirty bits from pack(), which also resets the dirty state afterwards. The dirty bits are transmitted beforehand, and do not need to be transmitted by the overriding method.

Version:: 1.0

Reimplemented from eq::fabric::Object.

template<class L, class V, class O>

virtual EQFABRIC_INL void eq::fabric::View< L, V, O >::setDirty ( const uint64_t bits ) [protected, virtual]

Add dirty flags to mark data for distribution.

Version:: 1.0

Reimplemented from eq::fabric::Serializable.

template<class L, class V, class O>

EQFABRIC_INL void eq::fabric::View< L, V, O >::setMaximumCapabilities ( const uint64_t bitmask )

Set the maximum desired capabilities for this view.

The capabilities returned by getCapabilities() during rendering match the lowest common denominator of all channel capabilities and this bitmask. Logically it has to be a superset of the minimum capabilities. By default all bits are set.

The capabilities are used to selectively disable source channels in conjunction with a load equalizer. Each channel typically sets its capabilities during configInit. The application sets the minimum and maximum capabilities needed or desired to render this view. The channel queries the capabilities to be used using getCapabilities().

Parameters:

bitmask the capabilities as bitmask

Version:: 1.0

template<class L, class V, class O>

EQFABRIC_INL void eq::fabric::View< L, V, O >::setMinimumCapabilities ( const uint64_t bitmask )

Set the minimum required capabilities for this view.

Any channel which does not support all of the bits in this mask does not execute any tasks. By default no bit is set.

Parameters:

bitmask the capabilities as bitmask

Version:: 1.0

template<class L, class V, class O>

EQFABRIC_INL void eq::fabric::View< L, V, O >::setObserver ( O * observer )

Set the entity tracking this view.
