Guide Section: Processing Object Data | EASAP Tree: DATA PROCESSING > LIST

OBJECT QUERY retrieves information on other objects in the EASAP.

OBJECT QUERY creates a list of object names or values.

OBJECT QUERY may retrieve the values of any parameter within an object.

A powerful feature of OBJECT QUERY is its recursive capability an OBJECT QUERY may be the target of an OBJECT QUERY (eg. an Author may create parameter name/value pairs for an object).

When an OBJECT QUERY is in 'Object Value' mode, and is pointed towards another OBJECT QUERY it will return the same output as the target OBJECT QUERY. This functionality can be used to concatenate object queries, or to add objects to the object query results. When in 'Object Value' mode and pointed towards a LIST reference, the list will be concatenated with any SCALAR values or other LISTs.

Essential Parameters:
Objects:List of objects to query.
Optional Parameters:
Query:Type of query (Object Name, Object Value, Parameter)
Parameter Name:
when Query Type: Parameter
Choose the name of the parameter in the target object for which to return a value.
Value on Error:
when Query Type: Object Value
The value to return if an error occurs when querying the object.
