Detailed Description

template<class C, class S, class CH>
class eq::fabric::Segment< C, S, CH >

Base data transport class for segments.

Member Typedef Documentation

template<class C, class S, class CH>
typedef LeafVisitor< S > eq::fabric::Segment< C, S, CH >::Visitor

The segment visitor type.

Version:
1.0

Definition at line 38 of file fabric/segment.h.


Member Enumeration Documentation

template<class C, class S, class CH>
enum eq::fabric::Segment::DirtyBits [protected]

The changed parts of the object since the last pack().

Subclasses should define their own bits, starting at DIRTY_CUSTOM.

Reimplemented from eq::fabric::Object.

Definition at line 172 of file fabric/segment.h.

template<class C, class S, class CH>
EQFABRIC_INL VisitorResult eq::fabric::Segment< C, S, CH >::accept ( Visitor visitor)

Traverse this segment using a segment visitor.

Parameters:
visitorthe visitor.
Returns:
the result of the visitor traversal.
Version:
1.0
template<class C, class S, class CH>
EQFABRIC_INL VisitorResult eq::fabric::Segment< C, S, CH >::accept ( Visitor visitor) const

Const-version of accept().

Version:
1.0
template<class C, class S, class CH>
virtual uint128_t eq::fabric::Segment< C, S, CH >::commit ( const uint32_t  incarnation = CO_COMMIT_NEXT) [virtual]

Commit a new version of this object.

Objects using the change type STATIC can not be committed.

Master instances will increment new versions continously, starting at VERSION_FIRST. If the object has not changed, no new version will be generated, that is, the current version is returned. The high value of the returned version will always be 0.

Slave objects can be commited, but have certain caveats for serialization. Please refer to the Programming Guide for more details. Slave object commits will return a random version on a successful commit, or VERSION_NONE if the object has not changed since the last commit. The high value of a successful commit will never be 0.

The incarnation count is meaningful for buffered master objects. The commit implementation will keep all instance data committed with an incarnation count newer than current_incarnation - getAutoObsolete(). By default, each call to commit creates a new incarnation, retaining the data from last getAutoObsolete() commit calls. When the application wishes to auto obsolete by another metric than commit calls, it has to consistently provide an incarnation counter. Buffers with a higher incarnation count than the current are discarded. A typical use case is to tie the auto obsoletion to an application-specific frame loop. Decreasing the incarnation counter will lead to undefined results.

Parameters:
incarnationthe commit incarnation for auto obsoletion.
Returns:
the new head version.

template<class C, class S, class CH>
virtual EQFABRIC_INL void eq::fabric::Segment< C, S, CH >::deserialize ( co::DataIStream ,
const uint64_t   
) [protected, virtual]

Worker for unpack() and applyInstanceData().

This function is called with the dirty bits send by the master instance. The dirty bits are received beforehand, and do not need to be deserialized by the overriding method.

template<class C, class S, class CH>
C* eq::fabric::Segment< C, S, CH >::getCanvas ( ) [inline]

template<class C, class S, class CH>
CH* eq::fabric::Segment< C, S, CH >::getChannel ( ) [inline]

Return the output channel of this segment.

Version:
1.0

Definition at line 76 of file fabric/segment.h.

template<class C, class S, class CH>
const CH* eq::fabric::Segment< C, S, CH >::getChannel ( ) const [inline]

Return the output channel of this segment.

template<class C, class S, class CH>
const Viewport& eq::fabric::Segment< C, S, CH >::getViewport ( ) const [inline]
Returns:
the segment's viewport.
Version:

template<class C, class S, class CH>
virtual EQFABRIC_INL void eq::fabric::Segment< C, S, CH >::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 C, class S, class CH>
virtual void eq::fabric::Segment< C, S, CH >::setDirty ( const uint64_t  bits) [protected, virtual]

Add dirty flags to mark data for distribution.

Version:
1.0

Reimplemented from co::Serializable.

template<class C, class S, class CH>
virtual EQFABRIC_INL void eq::fabric::Segment< C, S, CH >::setProjection ( const Projection projection) [virtual]

Set the frustum using a projection description.

Version:
1.0

Reimplemented from eq::fabric::Frustum.

template<class C, class S, class CH>
virtual EQFABRIC_INL void eq::fabric::Segment< C, S, CH >::setWall ( const Wall wall) [virtual]

Set the frustum using a wall description.

Version:

Reimplemented from eq::fabric::Frustum.

template<class C, class S, class CH>
virtual EQFABRIC_INL void eq::fabric::Segment< C, S, CH >::unsetFrustum ( ) [virtual]

Set the last specified frustum to TYPE_NONE.
