Examples with DatasetSpecification co.cask.cdap.api.dataset.DatasetSpecification used on opensource projects

Example 1 with DatasetSpecification

use of co.cask.cdap.api.dataset.DatasetSpecification in project cdap by caskdata.

the class InMemoryDatasetFramework method getInstances.

@Override
public Collection<DatasetSpecificationSummary> getInstances(NamespaceId namespaceId) {
    readLock.lock();
    try {
        // don't expect this to be called a lot.
        // might be better to maintain this collection separately and just return it, but seems like its not worth it.
        Collection<DatasetSpecification> specs = instances.row(namespaceId).values();
        ImmutableList.Builder<DatasetSpecificationSummary> specSummaries = ImmutableList.builder();
        for (DatasetSpecification spec : specs) {
