Example 1 with DataChannelSyncFilter

use of org.apache.cayenne.DataChannelSyncFilter in project cayenne by apache.

the class DataDomainFiltersIT method testOnSync_FilterOrdering.

@Test

    DataDomain domain = runtime.getDataDomain();
    List<String> results = new ArrayList<>();
    DataChannelSyncFilter f1 = (originatingContext, changes, syncType, filterChain) -> {
