All Implemented Interfaces:

java.lang.Cloneable, java.io.Externalizable, OreoConstants, Record, java.io.Serializable

Direct Known Subclasses:

AntiRecord

public class DefaultRecord

extends AbstractRecord

A concrete implementation of the Record interface In this implementation, the records can be written out as a human-readable string. This is the scheme used for serialization. DefaultRecord implements the java.io.Externalizable interface in order to avoid the general-purpose serialization scheme. The goal was that the resulting storage format should be human-readable and modifiable in a text editor in a pinch.

Method Detail

isImmutable

public boolean isImmutable()

Description copied from interface: Record

Have the fields all been set? Once a record is put in a DataSource, its fields are immutable.

setMetadata

public void setMetadata(RecordDescriptor desc)

Description copied from interface: Record

Method only used internally.

Specified by:

setMetadata in interface Record

Overrides:

setMetadata in class AbstractRecord

set

protected final void set(int i,
                         java.lang.Object value)

Specified by:

set in class AbstractRecord

get

protected final java.lang.Object get(int i)

Specified by:

get in class AbstractRecord

getMutableCopy

public Record getMutableCopy()

Description copied from class: AbstractRecord

create a clone. A shallow copy of the values array should be enough for immutable records Note that a newly cloned object has its immutable flag set to false, so that it is in a modifiable state.

Specified by:

getMutableCopy in interface Record

Overrides:

getMutableCopy in class AbstractRecord
