public class OJSchemaExpander

extends VariableBinder

Replaces references to the virtual members of SaffronSchema expressions.

Suppose that the variable schema implements SaffronSchema. Then field accesses of the form schema.field, and method calls of the form schema.method(arg0,...), become Java fragments like (Sales.Emp[]) schema.contentsAsArray("emps").

See SaffronConnection.contentsAsArray(java.lang.String, java.lang.String) for how these fragments are converted into efficient code.
