Detailed Description

A Part represents the combined key/data pair for a part entity.

In this sample, Part is bound to the stored key/data entry by implementing the MarshalledEnt interface, which is called by SampleViews.MarshalledEntityBinding.

The binding is "tricky" in that it uses this class for both the stored data entry and the combined entity object. To do this, the key field(s) are transient and are set by the binding after the data object has been deserialized. This avoids the use of a PartData class completely.

Since this class is used directly for data storage, it must be Serializable.

Member Function Documentation

void collections::ship::marshal::Part::marshalPrimaryKey (  TupleOutput  keyOutput  )  [inline]

Extracts the entity's primary key and writes it to the key output. Implements collections::ship::marshal::MarshalledEnt. Definition at line 108 of file Part.java. References com::sleepycat::bind::tuple::TupleOutput::writeString().

boolean collections::ship::marshal::Part::marshalSecondaryKey (  String  keyName, TupleOutput  keyOutput )  [inline]

Extracts the entity's index key and writes it to the key output. Implements collections::ship::marshal::MarshalledEnt. Definition at line 113 of file Part.java.

final void collections::ship::marshal::Part::setKey (  String  number  )  [inline, package]

Set the transient key fields after deserializing. This method is only called by data bindings. Definition at line 56 of file Part.java.

void collections::ship::marshal::Part::unmarshalPrimaryKey (  TupleInput  keyInput  )  [inline]

Completes construction of the entity by setting its primary key from the stored primary key. Implements collections::ship::marshal::MarshalledEnt. Definition at line 103 of file Part.java. References com::sleepycat::bind::tuple::TupleInput::readString().
