Interface ComplexAttribute

All Superinterfaces:

public interface ComplexAttribute
extends Attribute

A complex Atribtue holds a collection of attribute values in a single group.

Direct Access:

Note that the AttributeName name used above can be deterimed by examining the information available from getType().

It is recommended practice to formally use an Expression to access the contents of a ComplexAttribute, the Expression implementation will provide a more complete query langage then supported via direct access. Once again please use the information in getType() to assist in constructing useful Expressions.


Method Summary
 Collection<Association> associations()
          Convenience method for getting at the associations contained in this complex attribute.
 Collection<Attribute> attributes()
          Convenience method for getting at the attributes contained in this complex attribute.
 List<Property> get(Name name)
          Returns the subset of the attributes returned by #get() which match the specified name.
 AttributeDescriptor getDescriptor()
          Indicates the AttirbuteDescriptor for this content.
 ComplexType getType()
          Indicate the AttributeType, if we have a descriptor it will be in agreement.
 Collection<Property> getValue()
          Returns the value of the attribute, which is a list of other properties, attributes + associations..
 void setValue(Collection<Property> values)
          Sets the complete contents of this Attribute, that must be valid against the type's schema descriptor.

Method Detail

getType

ComplexType getType()
Description copied from interface: Attribute
Indicate the AttributeType, if we have a descriptor it will be in agreement.

Specified by:
getType in interface Attribute
Specified by:
getType in interface Property
Returns:
AttributeType information describing allowable content

getDescriptor

AttributeDescriptor getDescriptor()
Indicates the AttirbuteDescriptor for this content.

The attribute descriptor formally captures the name and multiplicity and type associated with this attribute.

Specified by:
getDescriptor in interface Attribute
Specified by:
getDescriptor in interface Property
Returns:
Descriptor for this attribute, if it is contained by another ComplexAttribute

setValue

void setValue(Collection<Property> values)
Sets the complete contents of this Attribute, that must be valid against the type's schema descriptor.

Throws:
IllegalArgumentException

getValue

Collection<Property> getValue()
Returns the value of the attribute, which is a list of other properties, attributes + associations..

Specified by:
getValue in interface Attribute
Returns:
Value Object of the class indicated by getType().getBinding()

attributes

Collection<Attribute> attributes()
Convenience method for getting at the attributes contained in this complex attribute.


associations

Collection<Association> associations()
Convenience method for getting at the associations contained in this complex attribute.

Returns:

get

List<Property> get(Name name)
Returns the subset of the attributes returned by #get() which match the specified name.

Parameters:
name - Name of attributes to return.
Returns:
List of attributes matching name, empty list if no match.
