Method Summary

JoinColumn	buildJoinColumn()
java.lang.Object	decode(java.lang.String aString) This method goes with encode().
java.lang.String	formatForSql(java.lang.Object obj, DatabasePolicy dbPolicy) This method overrides the superclass implementation.
java.lang.Class	getColumnClass() See IntegerColumnSpec for example of how to implement:
java.lang.Object	getColumnValueFrom(JDBCHelper helper) This ensures we get an Short (instead of a something else) from the JDBC driver.
java.lang.String	getSQLColumnType(DatabasePolicy dbPolicy) Return the ANSI standard SQL column type.

Method Detail

formatForSql

public java.lang.String formatForSql(java.lang.Object obj,
                                     DatabasePolicy dbPolicy)

This method overrides the superclass implementation.

Overrides:

formatForSql in class AbstractColumnSpec

Parameters:

obj - a value of type 'Object'

dbPolicy - a value of type 'DatabasePolicy'

Returns:

a value of type 'String'

getColumnClass

public java.lang.Class getColumnClass()

Description copied from class: AbstractColumnSpec

See IntegerColumnSpec for example of how to implement:

Overrides:

getColumnClass in class AbstractColumnSpec

getColumnValueFrom

public java.lang.Object getColumnValueFrom(JDBCHelper helper)
                                    throws java.sql.SQLException

This ensures we get an Short (instead of a something else) from the JDBC driver.

Overrides:

getColumnValueFrom in class AbstractColumnSpec

Parameters:

helper - a value of type 'JDBCHelper'

Returns:

a value of type 'Object'

Throws:

java.sql.SQLException - if an error occurs

decode

public java.lang.Object decode(java.lang.String aString)

This method goes with encode(). The String parameter must have been created by the encode() method.

Overrides:

decode in class AbstractColumnSpec

Parameters:

aString - a value of type 'String'

aPO - a value of type 'PersistentObject'

getSQLColumnType

public java.lang.String getSQLColumnType(DatabasePolicy dbPolicy)

Return the ANSI standard SQL column type.

Overrides:

getSQLColumnType in class AbstractColumnSpec

Parameters:

dbPolicy - a value of type 'DatabasePolicy'

Returns:

a value of type 'String'

buildJoinColumn

public JoinColumn buildJoinColumn()

Overrides:

buildJoinColumn in class AbstractColumnSpec

Following copied from class: com.is.jrf.AbstractColumnSpec

Returns:

a JoinColumn subclass instance with data from myself.
