Example 2 with IntStoreHeader

use of org.neo4j.kernel.impl.store.IntStoreHeader in project neo4j by neo4j.

the class PropertyRecordFormatTest method writeAndReadRecordWithRelativeReferences.

@Test
public void writeAndReadRecordWithRelativeReferences() throws IOException {
    int recordSize = recordFormat.getRecordSize(new IntStoreHeader(DATA_SIZE));
    long recordId = 0xF1F1F1F1F1F1L;
    int recordOffset = pageCursor.getOffset();
    PropertyRecord record = createRecord(recordFormat, recordId);
    recordFormat.write(record, pageCursor, recordSize);
    PropertyRecord recordFromStore = recordFormat.newRecord();
    recordFromStore.setId(recordId);
    resetCursor(pageCursor, recordOffset);
    recordFormat.read(recordFromStore, pageCursor, RecordLoad.NORMAL, recordSize);
    // records should be the same
    assertEquals(record.getNextProp(), recordFromStore.getNextProp());
    assertEquals(record.getPrevProp(), recordFromStore.getPrevProp());
    // now lets try to read same data into a record with different id - we should get different absolute references
    resetCursor(pageCursor, recordOffset);
    PropertyRecord recordWithOtherId = recordFormat.newRecord();
    recordWithOtherId.setId(1L);
    recordFormat.read(recordWithOtherId, pageCursor, RecordLoad.NORMAL, recordSize);
