Example 81 with PropertyBlock

use of org.neo4j.kernel.impl.store.record.PropertyBlock in project neo4j by neo4j.

the class PropertyRecordTest method addingDuplicatePropertyBlockShouldOverwriteExisting.

@Test
public void addingDuplicatePropertyBlockShouldOverwriteExisting() {
    // Given these things...
    PropertyRecord record = new PropertyRecord(1);
    PropertyBlock blockA = new PropertyBlock();
    blockA.setValueBlocks(new long[1]);
    blockA.setKeyIndexId(2);
    PropertyBlock blockB = new PropertyBlock();
    blockB.setValueBlocks(new long[1]);
    // also 2, thus a duplicate
    blockB.setKeyIndexId(2);
    // When we set the property block twice that have the same key
    record.setPropertyBlock(blockA);
    record.setPropertyBlock(blockB);
    // Then the record should only contain a single block, because blockB overwrote blockA
    List<PropertyBlock> propertyBlocks = Iterables.asList((Iterable<PropertyBlock>) record);
    assertThat(propertyBlocks, hasItem(blockB));
    assertThat(propertyBlocks, hasSize(1));
