Detailed Description

Description: An ON_NameHash is designed to help search for and compare attribute names like the ON_ModelComponent.Name() value.

If a name is wchar_t encoded as wide_char_name and UTF-8 encoded as utf8_name, then ON_NameHash(wide_char_name) == ON_NameHash(utf8_name).

Set: bool bEqualNameHash = ON_NameHash::Create(parent_id1,name1) == ON_NameHash::Create(parent_id2,name2); bool bEqualParentId = (parent_id1 == parent_id2) bool bEqualAttributeName = ON_String::EqualAttributeName(name1,name2);

If (bEqualParentId && bEqualAttributeName) is true, then bEqualNameHash is true. If bEqualParentId is false, then bEqualNameHash is false. With probability 1-epsilon, if bEqualAttributeName is false, then bEqualNameHash is false, where epsilon is an extremely tiny number.

Description: Internal_CreateFromDotNet() is public for technical reasons. It is used in Rhino Common p-invoke code that provides a .NET interface to the services ON_NameHash provided by the ON_NameHash class.

If you choose to ignore the preceding admonition, you will have to read the source code for information about how this function works.
