public class SQLDateColumnSpec

extends AbstractColumnSpec

This subclass of AbstractColumnSpec does java.sql.Date specific things. Note that this is not java.util.Date, but since java.sql.Date is a subclass of java.util.Date, there will be some compatibility.

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'

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, which uses the toString() method unless overidden. By Default the toString() and valueOf() methods both use the ANSI format, yyyy-mm-dd.

Overrides:

decode in class AbstractColumnSpec

Parameters:

aString - a value of type 'String'

Returns:

a value of type 'Object' (This actually will be a java.sql.Date or null)

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 method overrides the superclass implementation. This ensures that we get a boolean even if it is an Integer column.

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

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.
