Constructor Detail

ChoiceType

public ChoiceType()

Default constructor.

ChoiceType

public ChoiceType(ChoiceType ct)

Copy constructor.

ChoiceType

public ChoiceType(java.lang.String dataName)

Creates a new default type with no identity.

Parameters:

dataName - data name (may be null)

ChoiceType

public ChoiceType(java.lang.String dataName,
                  java.lang.String id,
                  java.lang.String format)

Creates a new choice data type from a choice pattern. The given pattern will be passed to a new Java ChoiceFormat object that will be used later to format data objects of this type.

This is the constructor the SQL type mapper Type.create(Integer,String,String,String) method will call to create a type that matches given SQL type.

Parameters:

dataName - data name (may be null)

id - type identity (may be null)

format - Java ChoiceFormat choice pattern (may be null)

FormatType.setFormat(java.util.Locale, java.lang.String)

ChoiceType

public ChoiceType(java.lang.String dataName,
                  java.lang.String id,
                  java.util.Map metaData,
                  java.util.Locale locale,
                  java.lang.String pattern,
                  java.lang.Object sample)

Creates a new choice type.

Parameters:

dataName - data name (may be null)

id - type identity (may be null)

metaData - type meta data map (may be null)

locale - type locale (may be null)

pattern - format pattern (may be null)

sample - format sample (may be null)

ChoiceType

protected ChoiceType(java.lang.String typeName,
                     java.lang.String dataName,
                     java.lang.String id,
                     java.util.Map metaData,
                     java.util.Locale locale,
                     java.lang.String pattern,
                     java.lang.Object sample)

Creates a new choice type.

Parameters:

typeName - type name
