convertDataValueToObjectValue in interface CoreConverter<DatabaseMapping,Session>

Parameters:

dataValue -

Returns:

Convert the value from XML by invoking the constructor that takes a spring parameter

isMutable

public boolean isMutable()

Description copied from interface: Converter

PUBLIC: If the converter converts the value to a mutable value, i.e. a value that can have its' parts changed without being replaced, then it must return true. If the value is not mutable, cannot be changed without replacing the whole value then false must be returned. This is used within the UnitOfWork to determine how to clone.

Specified by:

isMutable in interface Converter

initialize

public void initialize(DatabaseMapping mapping,
 Session session)

Description copied from interface: Converter

PUBLIC: Allow for any initialization.

Specified by:

initialize in interface Converter

Specified by:

initialize in interface CoreConverter<DatabaseMapping,Session>

setCustomClass

public void setCustomClass(Class<?> customClass)

getCustomClass

public Class<?> getCustomClass()
