Interface PropertyDefinition

All Known Implementing Classes:

AbstractPropertyDefinition, PropertyDefinitionImpl

public interface PropertyDefinition

Public interface for a property definition. A property definition is meta-data about a property that might be set on a Configurable Entity. It contains information such as the property's datatype, a default value, whether it is restricted to a set of allowable values, and whether it supports multiple values.

The property type constants here are imported from com.beasys.commerce.util.TypesHelper, and are duplicated here for convenience, and in case TypesHelper is not included in future releases.

You can use the no-arg constructor for the internal class com.bea.p13n.property.internal.PropertyDefinitionImpl when creating a PropertyDefinition. PropertyDefinitionImpl extends com.bea.p13n.property.AbstractPropertyDefinition. For example:

PropertyDefinitionImpl myPropSetDefImpl = new PropertyDefinitionImpl();
myPropSetDefImpl.setDescription(pdDesc);
myPropSetDefImpl.setMultiValued(pdMV);
myPropSetDefImpl.setRestricted(pdRest);
myPropSetDefImpl.setType(pdType);
myPropSetDefImpl.setDefaultValue(pdDefVal);
myPropSetDefImpl.setRestrictedValues(pdRestVals);

The setType() will use constants described below under the Field Summary Section.

Constants Summary

Method Detail

getDescription

String getDescription()

Get the description of this property

getType

int getType()

Get the datatype of the property

isMultiValued

boolean isMultiValued()

Can this property support multiple values?

isRestricted

boolean isRestricted()

Is this property restricted to a certain list of values?

getRestrictedValues

Collection getRestrictedValues()

Get the allowable values, if this property is restricted. Note: this does a shallow clone to prevent the collection from being modified, but if any property values are mutable, care must be taken not to modify them.

Returns

a Collection of allowable values, or null if there are none

getDefaultValue

Object getDefaultValue()

Get the default value for this property. If it is multivalued, this might be a collection of values. Note: this returns a clone of the default value; if it is a collection, and the property values are mutable objects, care must be taken not to modify them.

Returns

the default value, or null if there is none

validate

void validate(Object value)
              throws PropertyValidationException

Check to see if a value is valid for this property definition.

Throws

PropertyValidationException - if the value is not valid.
