public AttributeMap()

Default constructor.

AttributeMap

public AttributeMap(AttributeMap copy)

Parameters:

copy - the attribute map that should be copied.

Method Detail

clone

public java.lang.Object clone()

Creates a copy of this map.

Returns:

the clone.

setAttribute

public java.lang.Object setAttribute(java.lang.String namespace,
                                     java.lang.String attribute,
                                     java.lang.Object value)

Defines the attribute for the given namespace and attribute name.

Parameters:

namespace - the namespace under which the value should be stored.

attribute - the attribute name under which the value should be stored within the namespace.

value - the value.

Returns:

the previously stored value at that position.

getAttribute

public java.lang.Object getAttribute(java.lang.String namespace,
                                     java.lang.String attribute)

Returns the attribute value for the given namespace and attribute-name.

Parameters:

namespace - the namespace.

attribute - the attribute name.

Returns:

the value or null, if there is no such namespace/attribute name combination.

getFirstAttribute

public java.lang.Object getFirstAttribute(java.lang.String attribute)

Looks up all namespaces and returns the value from the first namespace that has this attribute defined. As the order of the namespaces is not defined, this returns a random value and the namespace used is undefined if more than one namespace contains the same attribute.

Parameters:

attribute - the the attribute name.

Returns:

the object from the first namespace that carries this attribute or null, if none of the namespaces has such an attribute defined.

getAttributes

public java.util.Map getAttributes(java.lang.String namespace)

Returns all attributes of the given namespace as unmodifable map.

Parameters:

namespace - the namespace for which the attributes should be returned.

Returns:

the map, never null.

getNames

public java.lang.String[] getNames(java.lang.String namespace)

Returns all names for the given namespace that have values in this map.

Parameters:

namespace - the namespace for which known attribute names should be looked up.

Returns:

the names stored for the given namespace.

getNameSpaces

public java.lang.String[] getNameSpaces()

Returns all namespaces that have values in this map.

Returns:

the namespaces stored in this map.
