All Implemented Interfaces:

IDDMSComponent

public final class Source
extends AbstractQualifierValue

An immutable implementation of ddms:source.

Strictness
DDMSence allows the following legal, but nonsensical constructs: A source element can be used with none of the attributes set.

Attributes
ddms:qualifier: specifies the source of the type vocabulary (optional) ddms:value: includes terms describing general categories, functions, genres, or aggregation levels (optional) ddms:schemaQualifier: the schema type (optional) ddms:schemaHref: a resolvable reference to the schema (optional) SecurityAttributes: The classification and ownerProducer attributes are optional. (starting in DDMS 3.0)

Since:

0.9.b

Constructor Detail

Source

public Source(nu.xom.Element element)
       throws InvalidDDMSException

Constructor for creating a component from a XOM Element

Parameters:

element - the XOM element representing this

Throws:

InvalidDDMSException - if any required information is missing or malformed

Source

public Source(String qualifier,
      String value,
      String schemaQualifier,
      String schemaHref,
      SecurityAttributes securityAttributes)
       throws InvalidDDMSException

Constructor for creating a component from raw data

Parameters:

qualifier - the value of the qualifier attribute

value - the value of the value attribute

schemaQualifier - the value of the schemaQualifier attribute

schemaHref - the value of the schemaHref attribute

securityAttributes - any security attributes (optional)

Throws:

InvalidDDMSException - if any required information is missing or malformed

Method Detail

validate

protected void validate()
                 throws InvalidDDMSException

Validates the component.

Rules
The qualified name of the element is correct. If a schemaHref is present, it is a valid URI. The SecurityAttributes do not exist until DDMS 3.0 or later.

Overrides:

validate in class AbstractBaseComponent

Throws:

InvalidDDMSException - if any required information is missing or malformed

See Also:

AbstractBaseComponent.validate()

validateWarnings

protected void validateWarnings()

Validates any conditions that might result in a warning.

Rules
A completely empty ddms:source element was found.

Overrides:

validateWarnings in class AbstractBaseComponent

getOutput

public String getOutput(boolean isHTML,
               String prefix,
               String suffix)

Description copied from class: AbstractBaseComponent

Renders this component as HTML or Text, with an optional prefix to nest it.

Specified by:

getOutput in class AbstractBaseComponent

Parameters:

isHTML - true for HTML, false for Text.

prefix - an optional prefix to put on each name.

suffix - an optional suffix to append to each name, such as an index.

Returns:

the HTML or Text representation of this component

See Also:

AbstractBaseComponent.getOutput(boolean, String, String)

equals

public boolean equals(Object obj)

Description copied from class: AbstractBaseComponent

Test for logical equality.

The base case tests against the name value and namespaceURI, as well as any child components classified as "nested components" and any security attributes. Extending classes may require additional rules for equality. This case automatically includes any nested components or security attributes.

Overrides:

equals in class AbstractQualifierValue

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Description copied from class: AbstractBaseComponent

Returns a hashcode for the component.

This automatically includes any nested components or security attributes.

Overrides:

hashCode in class AbstractQualifierValue

See Also:

Object.hashCode()

getName

public static String getName(DDMSVersion version)

Accessor for the element name of this component, based on the version of DDMS used

Parameters:

version - the DDMSVersion

Returns:

an element name

getSchemaQualifier

public String getSchemaQualifier()

Accessor for the value of the schema qualifier

getSchemaHref

public String getSchemaHref()

Accessor for the value of the schema href

getSecurityAttributes

public SecurityAttributes getSecurityAttributes()

Accessor for the Security Attributes. Will always be non-null, even if it has no values set.

Specified by:

getSecurityAttributes in interface IDDMSComponent

Overrides:

getSecurityAttributes in class AbstractBaseComponent
