public class SaffronSchemaExpander

extends VariableBinder

Replaces references to the virtual members of Schema expressions.

Suppose that the variable schema implements Schema. 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 Connection.contentsAsArray(java.lang.String) for how these fragments are converted into efficient code.
