progress.data.JSDO class
Table 10: progress.data.JSDO properties (2 of 2)
Member
table reference property
(JSDO)
Brief description
(See also the reference entry)
A property on a JSDO that has the name of a
temp-table mapped by the Mobile resource for
which the current JSDO is created
useRelationships property A Boolean that specifies whether JSDO methods
that operate on table references in JSDO local
storage work with the table relationships defined in
the schema (that is, work only on the records of a
child table that are related to the parent)
Methods Certain methods of the progress.data.JSDO class are called on the JSDO object
itself, without regard to a table reference, whether that reference is explicit (specified
in the method signature) or implicit (in the case of a JSDO containing only one
temp-table that is not explicitly specified). Other methods can be called on a reference
to a temp-table mapped by the Mobile resource for which the current JSDO is created.
