Constructor Detail

XAttributeImpl

protected XAttributeImpl(java.lang.String key)

Creates a new, empty attribute.

Parameters:

key - The key, i.e. unique name identifier, of this attribute.

XAttributeImpl

protected XAttributeImpl(java.lang.String key,
                         XExtension extension)

Creates a new attribute.

Parameters:

key - The key, i.e. unique name identifier, of this attribute.

extension - The extension used for defining this attribute.

Method Detail

getKey

public java.lang.String getKey()

Description copied from interface: XAttribute

Retrieves the key, i.e. unique identifier, of this attribute.

Specified by:

getKey in interface XAttribute

Returns:

The key of this attribute, as a string.

getExtension

public XExtension getExtension()

Description copied from interface: XAttribute

Retrieves the extension defining this attribute.

Specified by:

getExtension in interface XAttribute

Returns:

The extension of this attribute. May return null, if there is no extension defining this attribute.

getAttributes

public XAttributeMap getAttributes()

Description copied from interface: XAttributable

Retrieves the attributes set for this element.

Specified by:

getAttributes in interface XAttributable

Returns:

A map of attributes.

setAttributes

public void setAttributes(XAttributeMap attributes)

Description copied from interface: XAttributable

Sets the map of attributes for this element.

Specified by:

setAttributes in interface XAttributable

Parameters:

attributes - A map of attributes.

hasAttributes

public boolean hasAttributes()

Description copied from interface: XAttributable

Checks for the existence of attributes. This method can be a more efficient way of checking for the existance of attributes than using XAttributable.getAttributes() in certain situations.

Specified by:

hasAttributes in interface XAttributable

Returns:

whether this element has any attributes

getExtensions

public java.util.Set<XExtension> getExtensions()

Description copied from interface: XAttributable

Retrieves the extensions used by this element, i.e. the extensions used by all attributes of this element, and the element itself.

Specified by:

getExtensions in interface XAttributable

Returns:

A set of extensions.

clone

public java.lang.Object clone()

Description copied from interface: XAttribute

Attributes must be cloneable.

Specified by:

clone in interface XAttribute

Overrides:

clone in class java.lang.Object

Returns:

A clone of this attribute.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

compareTo

public int compareTo(XAttribute o)

Specified by:

compareTo in interface java.lang.Comparable<XAttribute>

accept

public void accept(XVisitor visitor,
                   XAttributable parent)

Specified by:

accept in interface XAttribute
