progress.data.JSDO class Notes • For more information on defining a Mobile interface, including the built-in CRUD and non-built-in invoke operations of a Mobile resource, see Chapter 3, “Creating Mobile Services.” • The JSDO supports a working record for each temp-table referenced in its local storage. Certain methods set a specific record as the working record. After other methods execute, there is no working record or existing working records remain unchanged. When there is a working record, you can access the fields of the record using one of the following mechanisms: Syntax jsdo.table-ref.field-ref jsdo.record.data.field-ref // Read only when a single table-ref is defined jsdo.table-ref.record.data.field-ref // Read only jsrecord-ref.data.field-ref // Read only jsdo The reference to a JSDO, and if the JSDO has only one temp-table, an implied reference to the working record defined for that temp-table. table-ref A table reference with the name of a temp-table in jsdo local storage and a reference to the temp-table working record. There is one table reference in a JSDO for each temp-table referenced by the JSDO. field-ref record data A field reference on a table-ref, or a property on the data property object, with the name and value of a field in the working record of the referenced temp-table. There is one such field reference and data object property for each field defined in the temp-table schema. A property of type JSRecord on a table reference, which references the working record of a temp-table specified by: • jsdo.table-ref • jsdo if the JSDO has only one temp-table If the JSDO has more than one temp-table, the record property is null at the JSDO level and is available only on a table-ref. A property on a JSRecord object with the field values for the working record specified by: • jsdo.table-ref • jsdo if the JSDO has only one temp-table • js-record of an associated JSDO temp-table 162 OpenEdge ® Development: Mobile Applications
progress.data.JSDO class Note: If a field-ref has the same name as a built-in property or method of the JSDO, you must use the data property to reference its value in the working record. Caution: Never write directly to a field-ref using this data property; in this case, use field-ref only to read the data. Writing to data using such a reference does not mark the record for update when calling the saveChanges( ) method. To mark a record for update, you must assign a field value either by setting a jsdo.table-ref.field-ref for a working record or by calling the assign( ) method on a valid table-ref or JSRecord object reference. jsrecord-ref A reference to a JSRecord object of a temp-table in JSDO local storage. You can return a jsrecord-ref for a working record as the value of the record property or as a value returned by supported JSDO built-in methods that return a working record, such as add( ) and find( ). For more information on the properties available to reference working record fields using this syntax, see Table 10 and Table 8. For more information on the methods for setting the working record for referenced temp-tables, see Table 11 and Table 9. • Many JSDO built-in methods are actually invoked on a JSDO table reference, and can only be invoked on the JSDO itself when its local storage is initialized with a single temp-table. • For a multi-table ProDataSet, the JSDO accesses the data for all unrelated temp-tables in local storage as top-level tables of the JSDO. Access to data for all related child temp-tables depends on the working record of the parent temp-table in the JSDO and the setting of the useRelationships property.
