Interface StructType

All Superinterfaces:

PropertyType, Serializable

public interface StructType
extends PropertyType

Describes an XMP array property. There are four types of arrays:

• Bag
(unorderen array)
• Seq
(ordered array)
• Alt
(alternative array)
• Alt-Text
(language alternative, syntactically equal to Alt, but contains only text properties with a language qualifier)

Additionally, a rule can be added to contrain an array to have a minimum and/or maximum number of Items (LengthRule).

Method Detail

getDefaultNamespaceURI

String getDefaultNamespaceURI()

The default namespace is the namespace that most struct fields are in. All structs defined in the XMP Specifications contain field only from a single namespace. Though, the XMP data model allows structs that contain fields of multiple namespaces.

Returns:

Returns the default namespace of the struct.

addField

void addField(PropertyDescription field)

Adds a struct field. If the field has no namespace defined, it inherits the default namespace of the struct.

Parameters:

field - the struct field to add

getField

PropertyDescription getField(String namespaceURI,
                             String localName)

Returns a struct field by namespace and local name.

Parameters:

namespaceURI - a namespace

localName - the name of a struct field

Returns:

Returns the struct field if found, null otherwise.

getFields

List<PropertyDescription> getFields()

Returns:

Returns a collection of all struct fields. The order of the added fields should be kept.

removeField

void removeField(String namespaceURI,
                 String localName)

Removes a struct field by namespace and local name. If it is not existing, the call is ignored.

Parameters:

namespaceURI - a namespace

localName - the name of the struct field to delete
