  +--com.solarmetric.rd.kodo.impl.jdbc.schema.ClassSequenceFactory

All Implemented Interfaces:

SequenceFactory

public class ClassSequenceFactory

extends java.lang.Object

implements SequenceFactory

SequenceFactory implementation that uses a sequence per class to generate numbers. It checks for the extension "sequence" under class-level metadata.

Note that much of the code here is duplicated across TrueSequenceFactory. The code is seperated for clarity to plug-in developers.

Field Summary

static java.lang.String

SEQUENCE_EXT

Constructor Summary

ClassSequenceFactory()

Method Summary

java.lang.String	getFormat() Return the MessageFormat string to use as for SQL generation.
long	getNext(java.lang.Class cls, java.lang.String user, java.lang.String pass) Return a unique primary key value.
java.lang.String	getTableName() Return the table name to run sequence queries against.
void	setConfiguration(com.solarmetric.rd.kodo.impl.jdbc.conf.JDBCConfiguration conf) Set the configuration for this factory; allows access to database connection information, etc.
void	setFormat(java.lang.String messageFormat) Set the string used for MessageFormat to generate the sequence selecting SQL.
void	setTableName(java.lang.String name) Set the table name to run sequence queries against.

Method Detail

getTableName

public java.lang.String getTableName()

Return the table name to run sequence queries against.

setTableName

public void setTableName(java.lang.String name)

Set the table name to run sequence queries against. Defaults to DUAL.

Parameters:

name - the name of the table

getFormat

public java.lang.String getFormat()

Return the MessageFormat string to use as for SQL generation.

setFormat

public void setFormat(java.lang.String messageFormat)

Set the string used for MessageFormat to generate the sequence selecting SQL. Should have two placeholders: {0} for the sequence name and {1} for the table name (e.g. dual). Also, it converts $ to spaces to help with auto configuration Defaults to select {0}.NEXTVAL from {1}.
