Interface OperatorSource

All Known Implementing Classes:

DynamicOperatorSourceWrapper, OperatorFactoryDB, OperatorSourceImpl, OperatorSourceWrapper

public interface OperatorSource

This resembles a Data source of Special Arguments for any expression such as Operands, Functions and Variables, etc.. The dataSource can be the memmory, a data base, or a remote data source. For a set of a default DataSource see OperatorFactoryDB
