Detailed Description

The general interface for importing mesh data into XDE document.

The tool implements auxiliary structures for creating an XDE document in two steps: 1) Creating TopoDS_Shape hierarchy (myRootShapes) and Shape attributes (myAttribMap) separately within performMesh(). Attributes include names and styles. 2) Filling XDE document from these auxiliary structures. Named elements are expanded within document structure, while Compounds having no named children will remain collapsed. In addition, unnamed nodes can be filled with generated names like "Face", "Compound" via generateNames() method, and the very root unnamed node can be filled from file name like "MyModel.obj".

◆ ToFillIncompleteDocument()

Standard_Boolean RWMesh_CafReader::ToFillIncompleteDocument ( ) const

inline

Partial read means unexpected end of file, critical parsing syntax errors in the middle of file, or reached memory limit indicated by performMesh() returning FALSE. Partial read allows importing a model even in case of formal reading failure, so that it will be up to user to decide if processed data has any value.

In case of partial read (performMesh() returns FALSE, but there are some data that could be put into document), Perform() will return TRUE and result flag will have failure bit set.
