Table 6.214—DRM_Property_Table

Property

Description

Superclass

Class

· <DRM Property Table>

Subclass

· none

Definition

An object of this DRM class specifies a <DRM Data Table> containing no location information, and therefore no spatial <DRM Axis>s.

Example(s)

· Externally Controlled Table-Based Animation

A DRM_Scale_Control_Link is to be driven using values from a DRM_Property_Table. The table value that is to be used is to be specified from outside the transmittal. The DRM_Scale_Control_Link would contain the DRM_Predefined Function FUNC_TABLE_VALUE. This would contain a DRM_Property_Table_Reference with an association to the DRM_Property_Table that contains the scale values. The DRM_Property_Table would be of table_type ECC_CONTROL VALUES and have a DRM_Table_Property Description specified by EAC_CONTROL_VALUE_SCALE_AMOUNT. Which value is referenced from the DRM_Property_Table would be controlled by a DRM_Property_Table_Reference_Control_Link that is contained in the DRM_Property_Table_Reference. This in turn would be driven by a DRM_Variable. To provide the hook for this DRM_Variable to be set from outside, the DRM_Variable would be associated with an DRM_Interface_Template.

An instance diagram is given below:

· Cyclic Table-Based Animation

A DRM_Translation_Control_Link is to be driven using values from a DRM_Property_Table. The table values that are to be used are to be cycled through 8 times with each cycle taking 10 seconds. This sequence of cycles is to be triggered from outside the transmittal. The DRM_Translation_Control_Link would contain the Predefined_Function.html FUNC_TABLE_VALUE. This would contain a DRM_Property_Table_Reference with an association to the DRM_Property_Table that contains the translation values. The DRM_Property_Table would be of table_type ECC_CONTROL_VALUES and have a DRM_Table_Property_Description specified by EAC_CONTROL_VALUE_TRANSLATION_AMOUNT. Which value is referenced from the DRM_Property_Table would be controlled by a DRM_Property_Table_Reference_Control_Link that is contained in the DRM_Property_Table_Reference. This in turn would be driven by the FUNC_CYCLE_TIME Predefined_Function.html. The cycle length (10 seconds) and the number of cycles (8) are specified by arguments to the function. The function is triggered by a DRM_Variable. To provide the hook for this DRM_Variable to be set from outside, the DRM_Variable would be associated with an DRM_Interface_Template.

· Function-Driven Table-Based Animation

A DRM_Rotation_Control_Link is to be driven using values from a DRM_Property_Table. The table value that is to be used is to be specified by the simulation's wind speed in order to rotate a wind sock to the appropriate elevation. The DRM_Rotation_Control_Link would contain the DRM_Predefined_Function FUNC_TABLE_VALUE. This would contain a DRM_Property_Table_Reference with an association to the DRM_Property_Table that contains the rotation values. The DRM_Property_Table would be of table_type ECC_CONTROL_VALUES and have a DRM_Table_Property_Description specified by EAC_CONTROL_VALUE_ROTATION_ANGLE. Which value is referenced from the DRM_Property_Table would be controlled by a DRM_Property_Table_Reference_Control_Link that is contained in the DRM_Property_Table_Reference. This in turn would be driven by the FUNC_WIND_SPEED DRM_Predefined_Function.
