Detailed Description

Represents the basic MetaData object.

Constructor & Destructor Documentation

xn::OutputMetaData::OutputMetaData ( const XnUInt8 **  ppData )

inline

Ctor. Meant to be used by other MetaData objects.

Parameters

ppData

[in] A pointer to the data member of the meta data object.

virtual xn::OutputMetaData::~OutputMetaData ( )

inlinevirtual

Dtor. Frees any allocated data.

Member Function Documentation

XnStatus xn::OutputMetaData::AllocateData ( XnUInt32  nBytes )

inline

Allocated a writable buffer. If a previous buffer was allocated it will be freed (or reused if possible). Also see Meta Data Objects.

Parameters

nBytes

[in] The requested size for the buffer, in bytes.

const XnUInt8* xn::OutputMetaData::Data ( ) const

inline

Gets a pointer to the data.

Reimplemented in xn::SceneMetaData, xn::IRMetaData, and xn::DepthMetaData.

const XnUInt8*& xn::OutputMetaData::Data ( )

inline

Gets a pointer to the data.

Reimplemented in xn::SceneMetaData, xn::IRMetaData, and xn::DepthMetaData.

XnUInt32 xn::OutputMetaData::DataSize ( ) const

inline

Gets the data size, in bytes

XnUInt32& xn::OutputMetaData::DataSize ( )

inline

Gets the data size, in bytes

XnUInt32 xn::OutputMetaData::FrameID ( ) const

inline

Gets the frame ID

XnUInt32& xn::OutputMetaData::FrameID ( )

inline

Gets the frame ID

void xn::OutputMetaData::Free ( )

inline

Frees the writable buffer, if one was allocated.

const XnOutputMetaData* xn::OutputMetaData::GetUnderlying ( ) const

inline

Gets the C object that is wrapped by this object.

Reimplemented in xn::SceneMetaData, xn::AudioMetaData, xn::IRMetaData, xn::ImageMetaData, xn::DepthMetaData, and xn::MapMetaData.

XnOutputMetaData* xn::OutputMetaData::GetUnderlying ( )

inline

Gets the C object that is wrapped by this object.

Reimplemented in xn::SceneMetaData, xn::AudioMetaData, xn::IRMetaData, xn::ImageMetaData, xn::DepthMetaData, and xn::MapMetaData.

XnBool xn::OutputMetaData::IsDataNew ( ) const

inline

TRUE if data was updated since last call to any Update function.

XnBool& xn::OutputMetaData::IsDataNew ( )

inline

TRUE if data was updated since last call to any Update function.

XnStatus xn::OutputMetaData::MakeDataWritable ( )

inline

Allocates a buffer and copies current data to it, so that data can be edited. Also see Meta Data Objects.

XnUInt64 xn::OutputMetaData::Timestamp ( ) const

inline

Gets the timestamp

XnUInt64& xn::OutputMetaData::Timestamp ( )

inline

Gets the timestamp

XnUInt8* xn::OutputMetaData::WritableData ( )

inline

Gets a pointer to the writable buffer (see Meta Data Objects).

Reimplemented in xn::SceneMetaData, xn::IRMetaData, xn::ImageMetaData, and xn::DepthMetaData.
