Resource filters

Collection resources (such as Activities) can have a filter section. This section defines criteria the each member of the collection must meet in order to be accessible. They may be the only criteria that the resource must meet, or they may be in addition to other criteria added by PolicyCenter. (Filters are not used for individual element resources because you can use view and edit permissions to control the availability of an individual resource.)

The filter section consists of a list of one or more filter expressions. A filter expression can be:

• A Gosu expression that returns filter criteria, such as gw.rest.core.pl.common.v1.activities.AssignedActivitiesFilter.
• The keyword __nofilter, which indicates that there is no filter and all resources are accessible.

For example, the following code defines the filters for the Accounts resource (for a collection of accounts) as declared in the accountholder_core-1.0access.yaml file:

Accounts:
  filter: gw.rest.core.pc.account.v1.security.AccountHolderAccountsFilter
