public class ISOMetadata
extends ModifiableMetadata
implements IdentifiedObject, Serializable

The base class of ISO 19115 implementation classes. Each sub-classes implements one of the ISO Metadata interface provided by GeoAPI.

Limitations:

• Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
• Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use XML instead.

Since:

0.3

Field Summary

Fields

Modifier and Type	Field and Description
protected Collection<Identifier>	identifiers All identifiers associated with this metadata, or null if none.

Constructor Summary

Constructors

Modifier	Constructor and Description
protected	ISOMetadata() Constructs an initially empty metadata.

Field Detail

LOGGER

@Deprecated
public static final Logger LOGGER

Deprecated. Messages related to XML (un)marshalling are now logged to the "org.apache.sis.xml" logger.

The logger for warnings emitted by any class in the org.apache.sis.metadata.iso.* packages. Warnings are emitted when an action causes the lost of data. For example the "distance" and "equivalentScale" properties in DefaultResolution are mutually exclusive: setting one discards the other. In such case, a warning is logged.

identifiers

protected Collection<Identifier> identifiers

All identifiers associated with this metadata, or null if none. This field is initialized to a non-null value when first needed.

Constructor Detail

ISOMetadata

protected ISOMetadata()

Constructs an initially empty metadata.

ISOMetadata

protected ISOMetadata(Object object)

Constructs a new metadata initialized with the values from the specified object. If the given object is an instance of IdentifiedObject, then this constructor copies the collection of identifiers.

Parameters:

object - The metadata to copy values from, or null if none.

Method Detail

getStandard

public MetadataStandard getStandard()

Returns the metadata standard implemented by subclasses, which is ISO 19115.

Note for implementors

Subclasses shall not override this method in a way that depends on the object state, since this method may be indirectly invoked by copy constructors (i.e. is may be invoked before this metadata object is fully constructed).

Specified by:

getStandard in class AbstractMetadata

Returns:

The metadata standard, which is ISO 19115 by default.

getIdentifiers

public Collection<Identifier> getIdentifiers()

Specified by:

getIdentifiers in interface IdentifiedObject

getIdentifierMap

public IdentifierMap getIdentifierMap()

The default implementation returns a wrapper around the identifiers list. That map is live: changes in the identifiers list will be reflected in the map, and conversely.

Specified by:

getIdentifierMap in interface IdentifiedObject
