Interface Record

@UML(identifier="Record",
     specification=ISO_19103)
public interface Record

A list of logically related elements as (name, value) pairs in a dictionary. A record may be used as an implementation representation for features.

This class can be think as the equivalent of the Java Object class.

Method Summary

Modifier and Type	Method and Description
Map<MemberName,Object>	getAttributes() Returns the dictionary of all (name, value) pairs in this record.
RecordType	getRecordType() Returns the type definition of record.
Object	locate(MemberName name) Returns the value for an attribute of the specified name.
void	set(MemberName name, Object value) Set the value for the attribute of the specified name.

Method Detail

getRecordType

@UML(identifier="recordType",
     obligation=OPTIONAL,
     specification=ISO_19103)
RecordType getRecordType()

Returns the type definition of record. All attributes named in this record must be defined in the returned record type. In other words, the following relationship must holds:

• getRecordType().getAttributeTypes().keySet().containsAll(getAttributes().keySet())

This method can be think as the equivalent of the Java Object.getClass() method.

getAttributes

@UML(identifier="attributes",
     obligation=MANDATORY,
     specification=ISO_19103)
Map<MemberName,Object> getAttributes()

Returns the dictionary of all (name, value) pairs in this record. The returned map shall not allows key addition. It may allows the replacement of existing keys only.

RecordType.getAttributeTypes()

locate

@UML(identifier="locate",
     obligation=MANDATORY,
     specification=ISO_19103)
Object locate(MemberName name)

Returns the value for an attribute of the specified name. This is functionnaly equivalent to getAttributes().get(name). The type of the returned object is given by getRecordType().locate(name).

See Also:

RecordType.locate(org.opengis.util.MemberName)

set

@Extension
void set(MemberName name,
                    Object value)
             throws UnsupportedOperationException

Set the value for the attribute of the specified name. This is functionally equivalent to getAttributes().put(name,value). Remind that name keys are constrained to record type members only.

Parameters:

name - The name of the attribute to modify.

value - The new value for the attribute.

Throws:

UnsupportedOperationException - if this record is not modifiable.
