Detailed Description

template<class N, class P, class W, class V>
class eq::fabric::Pipe< N, P, W, V >

Base data transport class for pipes.

See also:: eq::Pipe

Definition at line 34 of file include/eq/fabric/pipe.h.

Member Typedef Documentation

typedef std::vector< W* > eq::fabric::Pipe< N, P, W, V >::Windows

A vector of pointers to windows.

Version:: 1.0

Definition at line 38 of file include/eq/fabric/pipe.h.

Member Enumeration Documentation

template<class N, class P, class W, class V>

Subclasses should define their own bits, starting at DIRTY_CUSTOM.

Reimplemented from eq::fabric::Object.

Definition at line 172 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

enum eq::fabric::Pipe::IAttribute

Pipe attributes.

Version:: 1.0

Enumerator:

IATTR_HINT_THREAD	Execute tasks in separate thread (default)
IATTR_HINT_CUDA_GL_INTEROP	Configure CUDA context.

Definition at line 114 of file include/eq/fabric/pipe.h.

Member Function Documentation

template<class N, class P, class W, class V>

EQFABRIC_INL VisitorResult eq::fabric::Pipe< N, P, W, V >::accept ( V & visitor )

Traverse this pipe and all children using a pipe visitor.

Parameters:

visitor the visitor.

Returns:: the result of the visitor traversal.

Version:: 1.0

template<class N, class P, class W, class V>

EQFABRIC_INL VisitorResult eq::fabric::Pipe< N, P, W, V >::accept ( V & visitor ) const

Const-version of accept().

Version:: 1.0

template<class N, class P, class W, class V>

virtual EQFABRIC_INL void eq::fabric::Pipe< N, P, W, 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 N, class P, class W, class V>

virtual ChangeType eq::fabric::Pipe< N, P, W, V >::getChangeType ( ) const [inline, protected, virtual]

Returns:: how the changes are to be handled.

Reimplemented from eq::fabric::Serializable.

Definition at line 168 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

uint32_t eq::fabric::Pipe< N, P, W, V >::getDevice ( ) const [inline]

Returns the device number of this pipe.

The device number identifies the X screen for systems using the X11/GLX window system, or the number of the virtual screen for the AGL window system. On Windows systems it identifies the graphics adapter. Normally the device identifies a GPU.

Returns:: the device number of this pipe, or EQ_UNDEFINED_UINT32.

Version:: 1.0

Definition at line 74 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

int32_t eq::fabric::Pipe< N, P, W, V >::getIAttribute ( const IAttribute attr ) const [inline]

Returns:: the value of a pipe integer attribute.

Version:: 1.0

Definition at line 128 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

const N* eq::fabric::Pipe< N, P, W, V >::getNode ( ) const [inline]

Returns:: the parent node of this pipe.

Version:: 1.0

Definition at line 43 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

N* eq::fabric::Pipe< N, P, W, V >::getNode ( ) [inline]

Returns:: the parent node of this pipe.

Version:: 1.0

Definition at line 41 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

const PixelViewport& eq::fabric::Pipe< N, P, W, V >::getPixelViewport ( ) const [inline]

Returns:: the pixel viewport.

Version:: 1.0

Definition at line 79 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

uint32_t eq::fabric::Pipe< N, P, W, V >::getPort ( ) const [inline]

Returns the port number of this pipe.

The port number identifies the X server for systems using the X11/GLX window system, i.e., the :<port>.<screen> of the DISPLAY name. It currently has no meaning on all other systems.

Returns:: the port number of this pipe, or EQ_UNDEFINED_UINT32.

Version:: 1.0

Definition at line 59 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

const Windows& eq::fabric::Pipe< N, P, W, V >::getWindows ( ) const [inline]

Returns:: the vector of child windows.

Version:: 1.0

Definition at line 46 of file include/eq/fabric/pipe.h.

template<class N, class P, class W, class V>

virtual EQFABRIC_INL void eq::fabric::Pipe< N, P, W, 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 N, class P, class W, class V>

virtual EQFABRIC_INL void eq::fabric::Pipe< N, P, W, 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.

Version:: 1.0

Reimplemented from eq::fabric::Object.

template<class N, class P, class W, class V>

virtual EQFABRIC_INL void eq::fabric::Pipe< N, P, W, V >::setDirty ( const uint64_t bits ) [protected, virtual]

Add dirty flags to mark data for distribution.

Version:: 1.0

Reimplemented from eq::fabric::Serializable.

Reimplemented in eq::Pipe.

template<class N, class P, class W, class V>

EQFABRIC_INL void eq::fabric::Pipe< N, P, W, V >::setPixelViewport ( const PixelViewport & pvp )

Set the pipe's pixel viewport.

If invalid, the OSPipe has to set it to the device viewport during configInit().

Parameters:

pvp	the viewport in pixels.
