Class AbstractPropertySet

java.lang.Object
  com.bea.p13n.property.AbstractPropertySet

All Implemented Interfaces

PropertySet, Serializable

Direct Known Subclasses:

PropertySetImpl

public abstract class AbstractPropertySet
extends Object
implements PropertySet, Serializable

Default implementation of a Property Sets, which is a logical grouping of property definitions. A Property Set can be defined to contain the definitions of a group of related properties, such as user preferences.

These property definitions are used by Configurable Entity EJB's to validate property values and retrieve default values for properties. They can also be used by tools to display a list of available properties for an entity.

Method Detail

getName

public String getName()

Get the name of this property set

Specified by:

getName in interface PropertySet

setName

public void setName(String s)

Set the name of this property set

getDescription

public String getDescription()

Get the description of this property set

Specified by:

getDescription in interface PropertySet

setDescription

public void setDescription(String s)

Set the description of this property set

getType

public String getType()

Get the type of this property set. The Type is a String that specifies what types of Entities are intended to use the properties defined in a property set. When a ConfigurableEntity EJB is deployed, it must define a variable PropertySetType in its deployment descriptor; at run-time, only property sets of that type will be used to validate properties for that entity.

Type is also used as a way to namespace property sets - two property sets can have the same name, as long as they are different types.

Specified by:

getType in interface PropertySet

setType

public void setType(String s)

Set the type of this property set. The Type is a String that specifies what types of Entities are intended to use the properties defined in a property set. When a ConfigurableEntity EJB is deployed, it must define a variable PropertySetType in its deployment descriptor; at run-time, only property sets of that type will be used to validate properties for that entity.

Type is also used as a way to namespace property sets - two property sets can have the same name, as long as they are different types.

getPropertyDefinitions

public Map<String,PropertyDefinition> getPropertyDefinitions()

Retrieve all the property definitions in this property set.

Specified by:

getPropertyDefinitions in interface PropertySet

Returns

a Map of property name -> PropertyDefinition objects that make up this property set; or null if the property set is empty

getPropertyDefinition

public PropertyDefinition getPropertyDefinition(String key)

Retrieve a particular PropertyDefinition by name.

Specified by:

getPropertyDefinition in interface PropertySet

Parameters

key - the name of the PropertyDefinition to retrieve

Returns

the named PropertyDefinition, or null if it does not exist

addPropertyDefinition

public void addPropertyDefinition(String name,
                                  PropertyDefinition value)

Add a property definition to the property set. This is NOT exposed in the public interface because property sets are read-only to the outside world.

Parameters

name - the new property's name

value - the new property definition
