JsonObject2Object Method

Converts a JsonObject into an OpenROAD object.

This method has the following syntax:

Object = JsonHandler.JsonObject2Object(jsonobj = JsonObject[, existing_obj = object]
[, default_class = class][, default_row_class = class])

This method has the following parameters:

jsonobj

Specifies the JsonObject from which attribute values are used to populate an OpenROAD object.

existing_obj

Specifies an existing OpenROAD object that should be populated (rather than creating a new one).

default_class

Specifies the class to be used by default to create the object (if the JsonObject does not contain a "classname" member).

default_row_class

Specifies the default Row_Class if the object to be populated is an ArrayObject (if the JsonObject does not contain a "row_class" member).

If the method is successful, it returns a reference to the OpenROAD object populated; otherwise, it returns NULL.

The following mapping rules between the JsonValue subclasses and OpenROAD types apply:

JsonValue subclass	OpenROAD Type
JsonNull	NULL value (of any type)
JsonNumber	decimal, float (any precision), integer (any size), money
JsonBoolean	Any numeric type (values: true=1, false=0) Note: There is no boolean type in OpenROAD.
JsonString	varchar, nvarchar, date For mapping to a date, an absolute date has to be specified in ISO8601 format: "yyyy-mm-ddThh:mi:ssZ" (for date with time) "yyyy-mm-dd" (for date without time)
JsonObject	Object If the IgnoreUnknownAttributes attribute of the JsonHandler is set to FALSE, then all members of the JsonObject must be serializeable attributes of the class of the object (see the SetSerializableClassAttributes() method).
JsonArray	There is no OpenROAD equivalent for the JsonArray. The only use of a JsonArray is as the "rows" member of a JsonObject, that is mapped to an OpenROAD ArrayObject. In this case the items in the JsonArray must be JsonObject instances.
