public AbstractCatalog()

Method Detail

parent

public Resolve parent(ProgressListener monitor)

Catalogs do not have a parent so null is returned.

We can consider adding a global 'root' parent - but we will wait until we find a need, or if users request.

Specified by:

parent in interface Resolve

Parameters:

monitor - Progress monitor used to report status while blocking. May be null.

Returns:

null as catalogs do not have a parent

getInfo

public CatalogInfo getInfo(ProgressListener monitor)
                    throws java.io.IOException

Aquire info on this Catalog.

This is functionally equivalent to: resolve(ICatalogInfo.class,monitor)

Specified by:

getInfo in interface Catalog

Returns:

ICatalogInfo resolve(ICatalogInfo.class,ProgressListener monitor);

Throws:

java.io.IOException

Catalog.resolve(Class, ProgressListener)

Indicate class and id.

Returns:

string representing this IResolve
