Detailed Description

This class parses the entire contents of a DXF file. It is up to the caller to go through the resulting entities and use what is desired.

Example:

std::vector<DxfEntity> entities;
std::vector<DxfLayer> layers;

DxfParser parser(fname, entities, layers);
bool bSuccess = parser.RetrieveEntities();
if (bSuccess)
{
    // Look through the entities and take what is needed.
}

Constructor & Destructor Documentation

DxfParser::DxfParser	(	const vtString &	sFileName,
		std::vector< DxfEntity > &	entities,
		std::vector< DxfLayer > &	layers
	)

Constructor. Pass in the filename to parse.

Member Function Documentation

bool DxfParser::RetrieveEntities

(

bool

progress_callbackint = NULL

)

This method will parse the entire file, collecting all entities that it finds.

Parameters

progress_callback

Pass a function to receive progress notification (values of 0 to 100) if desired. Optional.

Returns

Success. If failure, then call GetLastError() to get an informative error message.
