P	convertToProperty(org.jboss.metatype.api.values.MetaValue metaValue, D propertyDefinition) Given a MetaValue, create and return a corresponding Property with the specified PropertyDefinition.
void	populateMetaValueFromProperty(P property, org.jboss.metatype.api.values.MetaValue metaValue, D propertyDefinition) Given a Property and its PropertyDefinition, as well as a MetaValue, populate that MetaValue so it corresponds to the Property.
void	populatePropertyFromMetaValue(P property, org.jboss.metatype.api.values.MetaValue metaValue, D propertyDefinition) Given a Property and its PropertyDefinition, as well as a MetaValue, populate the Property so it corresponds to the MetaValue.

Method Detail

populateMetaValueFromProperty

void populateMetaValueFromProperty(P property,
                                   org.jboss.metatype.api.values.MetaValue metaValue,
                                   D propertyDefinition)

Given a Property and its PropertyDefinition, as well as a MetaValue, populate that MetaValue so it corresponds to the Property. If the Property is a list or a map, all descendant Property's should be added as descendants of the MetaValue.

Parameters:

property - the property to be copied

metaValue - the MetaValue to be populated; should not be null

propertyDefinition - the property's definition

convertToMetaValue

org.jboss.metatype.api.values.MetaValue convertToMetaValue(P property,
                                                           D propertyDefinition,
                                                           org.jboss.metatype.api.types.MetaType metaType)

Given a Property and its PropertyDefinition, create and return a corresponding MetaValue with the specified MetaType. If the Property is a list or a map, all descendant Property's should be represented as descendants of the returned MetaValue. Generally this method can simply create an empty MetaValue object and then delegate the population of the guts of the object to populateMetaValueFromProperty(Property, MetaValue, PropertyDefinition).

Parameters:

property - the property to be converted

propertyDefinition - the property's definition

metaType - the type of MetaValue that should be created and returned

Returns:

the MetaValue representation of the given Property

populatePropertyFromMetaValue

void populatePropertyFromMetaValue(P property,
                                   org.jboss.metatype.api.values.MetaValue metaValue,
                                   D propertyDefinition)

Given a Property and its PropertyDefinition, as well as a MetaValue, populate the Property so it corresponds to the MetaValue. If the MetaValue is a from of list or map, all descendant MetaValue's should be added as descendants of the Property.

Parameters:

property - the property to be populated; should not be null

metaValue - the MetaValue to be copied

propertyDefinition - the property's definition

convertToProperty

P convertToProperty(org.jboss.metatype.api.values.MetaValue metaValue,
                    D propertyDefinition)

Given a MetaValue, create and return a corresponding Property with the specified PropertyDefinition. If the MetaValue is a form of list or map, all descendant MetaValue's should be represented as descendants of the returned Property. Generally this method can simply create an empty Property object and then delegate the population of the guts of the object to populatePropertyFromMetaValue(Property, MetaValue, PropertyDefinition).

Parameters:

metaValue - the metaValue to be converted

propertyDefinition - the definition of the property to be created and returned

Returns:

the Property representation of the given MetaValue
