| ResourceContext | | abstract public class ResourceContext implements Constants(Code) | | Abstract definition of a contect for resource data, ie a collection of
attributes bound over a set of parameter values. The attributes are
implemented as DataFormula instances.

| ResourceContext | | protected ResourceContext(String[] parameters, ResourceContext parent) throws ParameterError(Code) | | Standard constructor. It verifies the parameters and adds the context to
the list of known contexts.
|
| delete | | protected void delete()(Code) | | |
| getContextClasses | | public List<String> getContextClasses()(Code) | | Returns a list of the classes of any ResourceContexts that have been
instantiated so far. This is only used by the ResourceContext gui.

instantiated so far. This is only used by the ResourceContext gui.
|
| getFormulaKinds | | public List<String> getFormulaKinds()(Code) | | Returns an list of Formula classes instantiated so far by this context.
Only used by the ResourceContext gui.
|

instantiated so far. This is only used by the ResourceContext gui.
|
| getParameters | | public String[] getParameters()(Code) | | Returns a list of the parameter bindings. So far this is only used by the
ResourceContext gui.
|

| verifyParameters | | abstract protected void verifyParameters(String[] parameters) throws ParameterError(Code) | | Subclasses should provide this method. It should verify that the given
parameters are correct in number, position, type and value, throwing
ParameterError if not.
