4 P21FileInfo

4.1 Overview

The P21FileInfo structure is used by the p21_get_file_info function to fill the statistical information obtained from a STEP Part 21 file.

STR name;

This member is the name of the file. This member should be set before calling the p21_get_file_info function.

unsigned long num_entities;

This member represents the total number of entities in the file. It is being set by the p21_get_file_info function.

unsigned long num_simple;

This member is a number of simple type entities. (Set by p21_get_file_info .)

unsigned long num_complex;

This member is a number of complex ( AND/OR ) type entities. (Set by p21_get_file_info .)

unsigned long num_types;

This member is a total number of entity types found in the file. (Set by p21_get_file_info .)

CArrayOfTypeCount histogram;

This member represents a histogram of types. It is an array of TypeCount structures. A TypeCount structure has two members:

    int m_nCount;    		// Number of type instances
    STR m_szType;    		// Type name

P21FileInfo();

The constructor creates an object with all counts set to zero.

~P21FileInfo();

The destructor removes all entries from the histogram member and then destroys the object itself.
