Class Name: Property Table

Superclass - <Data Table>

Subclasses

Definition

FAQs

Why is a <Property Table> permitted to aggregate other <Property Tables>?

This mechanism allows a <Property Table> cell data element to specify an index into the set of ordered <Property Table> components, so that any component <Property Table> can be "re-used" by many data cells. See Index Codes within Tables for further details.

Why isn't a <Property Table> allowed to aggregate <Property Grids>?

An object referencing a <Property Grid> shall specify a <Location> for the <Property Grid> origin, and a <Property Table> has no location information.

Why is a <Property Table> permitted to aggregate <Property Table References>?

This mechanism allows a <Property Table> cell data element to specify an index into the set of ordered <Property Table Reference> components, so that any component <Property Table Reference> can be "re-used" by many data cells, therefore referring to 'slices' of other <Property Tables> without replicating the information. See Index Codes within Tables for further details.

Can values from a <Property Table> be used to drive <Control Links>?

Yes; this is possible in the following way.

1. Store the values in cells of the < Property Table> such that their <Table Property Description>'s meaning is appropriate for the target <Control Link> that is to be driven.
2. Where the values are to be referenced in the controlling <Expression> of the target <Control Link>, place a <Predefined Function> SE_PREDEF_FUNC_TABLE_VALUE instance, which in turn contains an appropriate <Property Table Reference> as an argument, referencing the values in the <Property Table>.

The <Predefined Function> will thereby return the value referenced from the <Property Table> as the value that drives the target <Control Link>.

If desired, the < Property Table Reference> can itself be controlled using a < Property Table Reference Control Link>, allowing different values to be referenced from the < Property Table> based on a controlling <Expression>.

See Part 4, Volume 5 Control Link Technical Guide of the SEDRIS Documentation Set for further details, as well as the examples shown here.

Classification_Data

 Indicates the kind of information represented by the
 <Data Table>, such as terrain elevation or
 water characteristics.

Property_Table_Reference

 This provides a mechanism for the cells of the aggregate
 <Property Table> to reference 'slices' of other
 <Property Table> instances.
