Use the Asset-Importer-Lib Meta-Data-API right


The problem:

Think of the following situation: you want to import a model using Asset-Importer-Lib and store some values like the version of the current asset or the author / company. Or when you want to manage the models using modules for a much more efficient way for your SCM you need to store grouping information. How can you do that using the Asset-Importer-Lib?

The solution: The Metadata API:

Asset-Importer-Lib provides a meta-data API to offer a solution for these kind of use-cases. It is straight-forward to use:

// to allocated two entries
aiMetadata *data = aiMetadata::Alloc( 2 ); 
unsigned int index( 0 );
bool success( false );
const std::string key_int = "test_int";
// to store an int-key
success = data->Set( index, key_int, 1 );

// to store a string key
index = 1;
const std::string key = "test";
success = data->Set( index, key, aiString( std::string( "test" ) ) );

// Deallocate the data afterwards
aiMetaData::dealloc( data );

You can store an arbitrary number of items, supported datatypes are

int
float
double
aiString

The intermediate data-structure aiNode can store this data.
