Method Detail

internalConvertToString

protected String internalConvertToString(Object value)
                                  throws UtilsException

Description copied from class: AbstractConverter

Returns the default "toString" result on provided Object.

Overrides:

internalConvertToString in class AbstractConverter

Throws:

UtilsException

internalConvertToType

protected <T> T internalConvertToType(Class<T> type,
                                      Object value)
                               throws UtilsException

Description copied from class: AbstractConverter

Handles conversion to an handled type. If type is not handled, an Exception will be thrown.

Specified by:

internalConvertToType in class AbstractConverter

Throws:

UtilsException

isConvertibleToString

public static boolean isConvertibleToString(IAddon addon)
                                     throws MRuleInternalException

Tells if this specific Addon instance can be converted to a parseable String.

Throws:

MRuleInternalException

getTypes

public Class<?>[] getTypes()

Description copied from interface: IConverter

Returns types handled by the converter. The Array must not contain the exhaustive list of types, but might just precise a common mother class. The Array might contain primitive types.

registerAddonDefaultPersistantProperty

public static void registerAddonDefaultPersistantProperty(String implementationId,
                                                          String defaultPersistantProperty)

Allows to declare for all Addons the persistent property that might be used for "one-line" String persistence.
For example : Value Accessor will have its property "value" declared as default. This allows to write and parse "VALUE:my value" as a String
An addon with any other persistent property valued is not writable as a "one-line" String.
An addon with not default persistent property is not writable as a "one-line" String as soon as one of its properties is valued.
The default property MUST be either another writable Addon or a parsable Object (String, Number, Date, Boolean, Character, etc...) : anything with an existing registered Converter, but not a Map, a collection, an Array, etc ... This API might change in future release to allow writing of more than one single property.

Parameters:

implementationId - Addon unique implementation ID

defaultPersistantProperty - Addon default writable property.
