Inheritance diagram for ezParticleStream:

Protected Member Functions
virtual void	Initialize (ezParticleSystemInstance *pOwner)
virtual ezResult	UpdateStreamBindings () final override
	Internal method which needs to be implemented, gets the concrete stream bindings. This is called every time the streams are resized. Implementations should check that their required streams exist and are of the correct data types.
virtual void	Process (ezUInt64 uiNumElements) final override
	The actual method which processes the data, will be called with the number of elements to process.
virtual void	InitializeElements (ezUInt64 uiStartIndex, ezUInt64 uiNumElements) override
	The default implementation initializes all data with zero.

Protected Attributes
ezProcessingStream *	m_pStream
Protected Attributes inherited from ezProcessingStreamProcessor
ezProcessingStreamGroup *	m_pStreamGroup = nullptr
	Back pointer to the stream group - will be set to the owner stream group when adding the stream processor to the group. Can be used to get stream pointers in UpdateStreamBindings();.

Detailed Description

Base class for all particle streams.

Member Function Documentation

InitializeElements()

void ezParticleStream::InitializeElements ( ezUInt64  uiStartIndex, ezUInt64  uiNumElements  )

overrideprotectedvirtual

The default implementation initializes all data with zero.

Implements ezProcessingStreamProcessor.

Reimplemented in ezParticleStream_Position, ezParticleStream_Size, ezParticleStream_Color, ezParticleStream_Velocity, ezParticleStream_Axis, and ezParticleStream_Variation.

Process()

virtual void ezParticleStream::Process ( ezUInt64  uiNumElements )

inlinefinaloverrideprotectedvirtual

The actual method which processes the data, will be called with the number of elements to process.

Implements ezProcessingStreamProcessor.

UpdateStreamBindings()

ezResult ezParticleStream::UpdateStreamBindings ( )

finaloverrideprotectedvirtual

Internal method which needs to be implemented, gets the concrete stream bindings. This is called every time the streams are resized. Implementations should check that their required streams exist and are of the correct data types.

Implements ezProcessingStreamProcessor.
