Class HeapRecordId

    java.lang.Object
      com.sleepycat.db.HeapRecordId

    public class HeapRecordId

extends Object

Content used for the key in a Heap database record. Berkeley DB creates this value for you when you create a record in a Heap database. You should never create this structure yourself; Berkeley DB must create it for you. This structure is returned in the key DatabaseEntry parameter of the method that you use to add a record to the Heap database.

Constructor Summary
`HeapRecordId(int pgno, short indx)` Construct a new record id, given a page number and index.

Method Summary
`static HeapRecordId` | `fromArray(byte[] data)` Construct a HeapRecordId from a byte array, typically from a `DatabaseEntry`.
`static HeapRecordId` | `fromArray(byte[] data, ByteOrder order)` Construct a HeapRecordId from a byte array, typically from a `DatabaseEntry`.
`short` | `getIndex()` Get the index in the offset table where the record can be found.
`int` | `getPageNumber()` Get the database page number where the record is stored.
`void` | `setIndex(short indx)` Set the index in the offset table where the record can be found.
`void` | `setPageNumber(int pgno)` Set the database page number where the record is stored.
`byte[]` | `toArray()` Return a byte array representing this record id.
`byte[]` | `toArray(ByteOrder order)` Return a byte array representing this record id.
