Examples with ValuePartitioningPolicy org.eclipse.persistence.descriptors.partitioning.ValuePartitioningPolicy used on opensource projects

Example 1 with ValuePartitioningPolicy

use of org.eclipse.persistence.descriptors.partitioning.ValuePartitioningPolicy in project eclipselink by eclipse-ee4j.

the class ValuePartitioningMetadata method buildPolicy.

/**
 * INTERNAL:
 * Build/process the partitioning policy.
 */
@Override
public PartitioningPolicy buildPolicy() {
    ValuePartitioningPolicy policy = new ValuePartitioningPolicy();
    super.buildPolicy(policy);
    // Set the partition value type name. Will be used to initialize the
    // individual partition values.
    policy.setPartitionValueTypeName(getPartitionValueType().getName());
    // Set the default connection pool.
    policy.setDefaultConnectionPool(this.defaultConnectionPool);
    // Set only the partition value names (they will be initialized at runtime).
    for (ValuePartitionMetadata partition : getPartitions()) {
        policy.addPartitionName(partition.getValue(), partition.getConnectionPool());
