Detailed Description

Metadata transfer.

Metadata are used in cases when geometric or attribute model doesn't match structure of information from converters. Alternate tree sutrucure is a sample of metadata.

Member Function Documentation

InitMetadataForItem()

virtual bool IConverterMetadataReceiver::InitMetadataForItem ( const c3d::string_t &  category, const c3d::string_t &  nameInCategory, const c3d::string_t &  contentType  )

pure virtual

Initialize metadata transfer for item.

Should be called before metadata related to non-geometric element to prepare the reciever.

Parameters

[in]	category	- Category element belongs to.
[in]	nameInCategory	- Element's name in category.
[in]	contentType	- Representation of metadata.

Returns

Wether the metadata transfer is possible.

Note

Expected it is called once for each category - name pair.

CloseMetadataForItem()

virtual void IConverterMetadataReceiver::CloseMetadataForItem ( const c3d::string_t &  category, const c3d::string_t &  nameInCategory  )

pure virtual

Finalize metadata transfer for item.

Should be called after metadata related to non-geometric element to free related resources.

Parameters

[in]	category	- Category element belongs to.
[in]	nameInCategory	- Element's name in category.

Note

Expected it is called once for each category - name pair in case transfer is possible or not called otherwise.

TransferMetadataForItem()

virtual void IConverterMetadataReceiver::TransferMetadataForItem ( const c3d::string_t &  category, const c3d::string_t &  nameInCategory, const char *  metadataBuffer, unsigned long int  bufferCapacity  )

pure virtual

Transfer metadata block for item.

Parameters

[in]	category	- Category element belongs to.
[in]	nameInCategory	- Element's name in category.
[in]	metadataBuffer	- Binary buffer containing block data.
[in]	bufferCapacity	- Lenght of binary buffer containing block data.

Note

Many calls for each category - name are possible.
