Constructor Detail

EOAdaptor

public EOAdaptor(java.lang.String name)

Method Detail

adaptorWithModel

public static EOAdaptor adaptorWithModel(EOModel model)

Creates an adaptor with model's adaptorName and sets its connection dictionary to the model's connection dictionary.

Parameters:

model - The model to take adaptorName and connectionDictionary from.

Returns:

The adaptor specified in model.

adaptorWithName

public static EOAdaptor adaptorWithName(java.lang.String name)

Instantiates an adaptor of a concrete EOAdaptor subclass, based on name. If name is a fully qualified class name, then it returns an instance of that class by invoking the constructor with a string argument. Otherwise, it tries to find a class called (name)Adaptor in a package called net.wotonomy.(lowercase name)adaptor; if it can't find one, an exception is raised.

Parameters:

name - The name of the adaptor, or a fully qualified class name.

Returns:

setExpressionClassName

public static void setExpressionClassName(java.lang.String expClassName,
                                          java.lang.String adaptorClassName)
