com.gammastream.validity.GSVModel

public final class GSVModel

GSVModel used for the mapping validation rules to an entities' attributes.
The structure is very similar to Apple's EOModel.

Author:

GammaStream Technologies, Inc.

Field Summary

static java.lang.String	MODEL_EXTENSION The extension of the GSVModel file included in the '.eomodeld' wrapper. Currently the full name is: 'Validity.model'
static java.lang.String	MODEL_NAME The name of the GSVModel file included in the '.eomodeld' wrapper. Currently the full name is: 'Validity.model'

Constructor Summary

GSVModel(java.lang.String path)
Creates a new GSVModel using the path to an '.eomodeld' file.

Example of creating a GSVModel for the Movies example which ships with WebObjects.

EOModel eoModel = EOModelGroup.defaultGroup().modelNamed("Moview");
GSVModel model = new GSVModel(eoModel.path());
