Interface ModelAdaptor

All Known Implementing Classes:

AggregateModelAdaptor, MapModelAdaptor, ObjectModelAdaptor, STModelAdaptor

public interface ModelAdaptor

An object that knows how to convert property references to appropriate actions on a model object. Some models, like JDBC, are interface based (we aren't supposed to care about implementation classes). Some other models don't follow getter method naming convention. So, if we have an object of type M with property method foo() (not getFoo()), we register a model adaptor object, adap, that converts foo lookup to foo(). Given , we look up foo via the adaptor if "a instanceof(M)". See unit tests.

Method Summary

Object

getProperty(Interpreter interp, ST self, Object o, Object property, String propertyName) Lookup property name in o and return its value.

Method Detail

getProperty

Object getProperty(Interpreter interp,
                   ST self,
                   Object o,
                   Object property,
                   String propertyName)
                   throws STNoSuchPropertyException

Lookup property name in o and return its value. It's a good idea to cache a Method or Field reflection object to make this fast after the first look up. property is normally a String but doesn't have to be. E.g., if o is Map, property could be any key type. If we need to convert to string, then it's done by ST and passed in here.

Throws:

STNoSuchPropertyException
