Examples with RemoteProcessGroupStatusEntity org.apache.nifi.web.api.entity.RemoteProcessGroupStatusEntity used on opensource projects

Example 1 with RemoteProcessGroupStatusEntity

use of org.apache.nifi.web.api.entity.RemoteProcessGroupStatusEntity in project nifi by apache.

the class EntityFactory method createRemoteProcessGroupStatusEntity.

public RemoteProcessGroupStatusEntity createRemoteProcessGroupStatusEntity(final RemoteProcessGroupStatusDTO status, final PermissionsDTO permissions) {
    final RemoteProcessGroupStatusEntity entity = new RemoteProcessGroupStatusEntity();
    entity.setCanRead(permissions.getCanRead());
    // always set the status, as it's always allowed... just need to provide permission context for merging responses
    entity.setRemoteProcessGroupStatus(status);
    return entity;
}

Example 2 with RemoteProcessGroupStatusEntity

use of org.apache.nifi.web.api.entity.RemoteProcessGroupStatusEntity in project nifi by apache.

the class RemoteProcessGroupStatusEndpointMerger method mergeResponses.

@Override
