CounterProvider
public CounterProvider()
getOperations
public javax.xml.namespace.QName[] getOperations()
- Description copied from interface:
OperationProvider
- Called during initialization when the Grid service needs to find out
what operations are supported by this provider.
- Specified by:
getOperations
in interface OperationProvider
- Returns:
- an array of operation qnames as defined in WSDL. An
OperationProvider can use the empty string "" to denote that all
operations with a certain local name are implemented. Similarly
the wildcard "*" can be used in the local part of the qname to denote
that all operations within a certain namespace are implemented.
Combining these two approaches and returning:
new QName[] {new QName("","*")}
, will result in all
incoming operations being redirected to this provider (apart from the
OGSI defined GridService interface operations provided by the
GridServiceBase implementation. Note that individual
operations in the OGSI namespace could still be overridded with this
approach, but not using the 'all namespaces and all operation' wildcard.
