A vector of pointers to views.

Version:: 1.0

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

template<class C, class L, class V>

typedef ElementVisitor< L, LeafVisitor< V > > eq::fabric::Layout< C, L, V >::Visitor

The layout visitor type.

Member Enumeration Documentation

template<class C, class L, class V>

enum eq::fabric::Layout::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.

Member Function Documentation

template<class C, class L, class V>

EQFABRIC_INL VisitorResult eq::fabric::Layout< C, L, V >::accept ( Visitor & visitor )

Traverse this layout and all children using a layout visitor.

Parameters:

visitor the visitor.

Returns:: the result of the visitor traversal.

Version:: 1.0

template<class C, class L, class V>

EQFABRIC_INL VisitorResult eq::fabric::Layout< C, L, V >::accept ( Visitor & visitor ) const

Const-version of accept().

Version:: 1.0

template<class C, class L, class V>

virtual EQFABRIC_INL void eq::fabric::Layout< C, L, V >::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.

See also:: serialize()

Version:: 1.0

Reimplemented from eq::fabric::Object.

template<class C, class L, class V>

C* eq::fabric::Layout< C, L, V >::getConfig ( ) [inline]

Returns:: the current config.

Version:: 1.0

Definition at line 43 of file fabric/layout.h.

template<class C, class L, class V>

const C* eq::fabric::Layout< C, L, V >::getConfig ( ) const [inline]

Returns:: the current config.

Version:: 1.0

Definition at line 46 of file fabric/layout.h.

template<class C, class L, class V>

const Views& eq::fabric::Layout< C, L, V >::getViews ( ) const [inline]

Get the list of views.

Version:: 1.0

Definition at line 49 of file fabric/layout.h.

template<class C, class L, class V>

virtual EQFABRIC_INL void eq::fabric::Layout< C, L, V >::notifyDetach ( ) [protected, virtual]

Notify that this object will be deregistered or unmapped.

The method is called from the thread initiating the deregistration or unmapping, before the operation is executed.

See also:: isMaster()

Reimplemented from eq::fabric::Object.

template<class C, class L, class V>

virtual EQFABRIC_INL void eq::fabric::Layout< C, L, V >::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.
