All Implemented Interfaces:

Map<NamespaceName,String>

public class AttributeMap
extends AbstractMap<NamespaceName,String>

Facade which adds standard behaviour to the SAX attributes implementation. The access methods allow more convenient and consistent transitions on the state of the attribute collection. Nevertheless they operate directly on the "peer object" of type AttributesImpl. Standardized "map interface" methods are available which reflect the state of this peer. A correct map semantics is assumed for the underlying implementing object, but not checked. So repeated keys are not detected, but ignored in an unspecified way.

Constructor Details

AttributeMap

public AttributeMap(Attributes impl)

Constructs a new facade object for the given SAX attributes. Iff the argument is an instance of AttributesImpl, then write operations are supported. Otherwise read only.

AttributeMap

public AttributeMap()

Constructs a new facade object for an empty collection of SAX attributes.

AttributeMap

public AttributeMap(AttributeMap map)

Constructs a new facade object with the data from the given instance. A new implementing instance is created by calling new AttributesImpl(Attributes) from the SAX library.

Method Details

equals

public boolean equals(Object o)

Directly delegate to the implementing Attributes.

Specified by:

equals in interface Map<NamespaceName,String>

Overrides:

equals in class AbstractMap<NamespaceName,String>

hashCode

public int hashCode()

Directly delegate to the implementing Attributes.

Specified by:

hashCode in interface Map<NamespaceName,String>

Overrides:

hashCode in class AbstractMap<NamespaceName,String>

getImplementation

public Attributes getImplementation()

Return the underlying SAX API instance.

entrySet

public Set<Map.Entry<NamespaceName,String>> entrySet()

Deliver a view to the Sax implementation as required by AbstractSet.

Specified by:

entrySet in interface Map<NamespaceName,String>

Specified by:

entrySet in class AbstractMap<NamespaceName,String>

put

public String put(NamespaceName name,
 String value)

Evident

Specified by:

put in interface Map<NamespaceName,String>

Overrides:

put in class AbstractMap<NamespaceName,String>

remove

@Opt
public @Opt String remove(Object name)

Evident

Specified by:

remove in interface Map<NamespaceName,String>

Overrides:

remove in class AbstractMap<NamespaceName,String>

remove

@Opt
public @Opt String remove(NamespaceName name)

Evident

contentsToString

public static String contentsToString(Attributes attrs)

Auxiliary method to print the contents of a SAX Attributes object. This is a mere technical device with not "set" semantics: The SAX specification does not forbid that these are de-normalized and do not represent a valid XML data model.
