Detailed Description

Class represents a document reading filter.

It allows to set attributes (by class names) that must be skipped during the document reading or attributes that must be retrieved only. In addition it is possible to define one or several subtrees (by entry) which must be retrieved during the reading. Other labels are created, but no one attribute on them.

Member Typedef Documentation

◆ TagTree

typedef NCollection_DataMap<Standard_Integer, Standard_Address> PCDM_ReaderFilter::TagTree

protected

Map from tag of a label to sub-tree of this tag. Used for fast browsing the tree and compare with entities that must be read.

Member Enumeration Documentation

◆ AppendMode

enum PCDM_ReaderFilter::AppendMode

Supported modes of appending the file content into existing document.

Enumerator
AppendMode_Forbid	do not allow append, default mode
AppendMode_Protect	keeps existing attributes, reads only new ones
AppendMode_Overwrite	overwrites the existing attributes by the loaded ones
