Detailed Description

Represents the full data structure information for a single BLEND file.

This data is extracted from the DNA1 chunk in the file. #DNAParser does the reading and represents currently the only place where DNA is altered.

Member Function Documentation

AddPrimitiveStructures()

void DNA::AddPrimitiveStructures

(

)

Add structure definitions for all the primitive types, i.e.

integer, short, char, float

ConvertBlobToStructure()

std::shared_ptr< ElemBase > DNA::ConvertBlobToStructure	(	const Structure &	structure,
		const FileDatabase &	db
	)		const

Take an input blob from the stream, interpret it according to a its structure name and convert it to the intermediate representation.

Parameters

structure	Destination structure definition
db	File database.

Returns

A null pointer if no appropriate converter is available.

ExtractArraySize()

void DNA::ExtractArraySize ( const std::string &  out, size_t  array_sizes[2]  )

static

Extract array dimensions from a C array declaration, such as ...[4][6].

Returned string would be ...[][].

Parameters

out
array_sizes	Receive maximally two array dimensions, the second element is set to 1 if the array is flat. Both are set to 1 if the input is not an array.

Exceptions

DeadlyImportError

if more than 2 dimensions are encountered.

Get()

const Structure * Assimp::Blender::DNA::Get ( const std::string &  ss ) const

inline

GetBlobToStructureConverter()

DNA::FactoryPair DNA::GetBlobToStructureConverter	(	const Structure &	structure,
		const FileDatabase &	db
	)		const

Find a suitable conversion function for a given Structure.

Such a converter function takes a blob from the input stream, reads as much as it needs, and builds up a complete object in intermediate representation.

Parameters

structure	Destination structure definition
db	File database.

Returns

A null pointer in .first if no appropriate converter is available.

operator[]() [1/2]

const Structure & Assimp::Blender::DNA::operator[] ( const size_t  i ) const

inline

Access a structure by its index.

operator[]() [2/2]

const Structure & Assimp::Blender::DNA::operator[] ( const std::string &  ss ) const

inline

Access a structure by its canonical name, the pointer version returns NULL on failure while the reference version raises an error.

RegisterConverters()

void DNA::RegisterConverters

(

)

Fill the converters member with converters for all known data types.

The implementation of this method is in BlenderScene.cpp and is machine-generated. Converters are used to quickly handle objects whose exact data type is a runtime-property and not yet known at compile time (consier Object::data).
