Defined in File Ifc4.h
The IfcStateEnum enumeration identifies the state or accessibility of the object (for example, read/write, locked).
Valid enumerations are:
READWRITE: Object is in a Read-Write state. It may be modified by an application. READONLY: Object is in a Read-Only state. It may be viewed but not modified by an application. LOCKED: Object is in a Locked state. It may not be accessed by an application. READWRITELOCKED: Object is in a Read-Write-Locked state. It may not be accessed by an application. READONLYLOCKED: Object is in a Read-Only-Locked state. It may not be accessed by an application.
HISTORY New enumeration in IFC R2.0.
IFC2x3 CHANGE This concept was initially introduced in IFC 2.0 as IfcModifiedFlag of type BINARY(3) FIXED and has been modified in R2x to an enumeration. It was initially introduced as a first step towards providing facilities for partial model exchange from a server as requested by the IFC implementers. It is intended for use primarily by a model server so that an application can identify the state of the object.
