MWAPI - Attribute Definitions

Draft MDC Standard

☞

3.2 Attribute Definitions

Within this document, each attribute is defined with a table of the following format:

Definition Specifies the meaning of the attribute.
Domain Specifies the range of possible values for the attribute.
Access Specifies the ways in which the attribute can be accessed by an application:
Create Indicates that the application can assign a value for the attribute when the entity is created.
Modify For a wattribute, elattribute, cattribute, rowattribute, colattribute, or especattribute, Modify indicates that the application can assign a value to the attribute after the entity is created. For a dattribute or einfoattribute, Modify indicates that the application can assign a value to the attribute.
Reference Indicates that the application can obtain the current value of the attribute.
Default For a wattribute, elattribute, cattribute, or especattribute, Default specifies the value of the attribute if no value is assigned when the entity is created. For a dattribute or einfoattribute, Default specifies the value of the attribute prior to any assignment of a value to it by the application. In addition to specific default values, the following general default value types are defined.
None Indicates that no default value is defined and the attribute node is undefined.
Platform Indicates that the default is established by the underlying windowing platform, if there is one, and by the implementation of the MWAPI otherwise. The attribute node may be undefined.
Not Applicable Indicates that no default applies because the attribute can only be referenced.
