javax.swing.text
public class: StyleContext.NamedStyle [javadoc | source]

java.lang.Object
   javax.swing.text.StyleContext$NamedStyle

All Implemented Interfaces:
    Style, Serializable

A collection of attributes, typically used to represent character and paragraph styles. This is an implementation of MutableAttributeSet that can be observed if desired. These styles will take advantage of immutability while the sets are small enough, and may be substantially more efficient than something like SimpleAttributeSet.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see java.beans.XMLEncoder .

Field Summary
protected  EventListenerList	listenerList	The change listeners for the model.
protected transient  ChangeEvent	changeEvent	Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this".

Constructor:
public NamedStyle() { attributes = getEmptySet(); } Creates a new named style, with a null name and parent.
public NamedStyle(Style parent) { this(null, parent); } Creates a new named style. Parameters: parent - the parent style, null if none since: 1.4 -
public NamedStyle(String name, Style parent) { attributes = getEmptySet(); if (name != null) { setName(name); } if (parent != null) { setResolveParent(parent); } } Creates a new named style. Parameters: name - the style name, null for unnamed parent - the parent style, null if none since: 1.4 -

Method from javax.swing.text.StyleContext$NamedStyle Detail:
public void addAttribute(Object name, Object value) { StyleContext context = StyleContext.this; attributes = context.addAttribute(attributes, name, value); fireStateChanged(); } Adds an attribute.
public void addAttributes(AttributeSet attr) { StyleContext context = StyleContext.this; attributes = context.addAttributes(attributes, attr); fireStateChanged(); } Adds a set of attributes to the element.
public void addChangeListener(ChangeListener l) { listenerList.add(ChangeListener.class, l); } Adds a change listener.
public boolean containsAttribute(Object name, Object value) { return attributes.containsAttribute(name, value); } Checks whether a given attribute name/value is defined.
public boolean containsAttributes(AttributeSet attrs) { return attributes.containsAttributes(attrs); } Checks whether the element contains all the attributes.
public AttributeSet copyAttributes() { NamedStyle a = new NamedStyle(); a.attributes = attributes.copyAttributes(); return a; } Copies a set of attributes.
protected void fireStateChanged() { // Guaranteed to return a non-null array Object[] listeners = listenerList.getListenerList(); // Process the listeners last to first, notifying // those that are interested in this event for (int i = listeners.length-2; i >=0; i-=2) { if (listeners[i]==ChangeListener.class) { // Lazily create the event: if (changeEvent == null) changeEvent = new ChangeEvent(this); ((ChangeListener)listeners[i+1]).stateChanged(changeEvent); } } } Notifies all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.
public Object getAttribute(Object attrName) { return attributes.getAttribute(attrName); } Gets the value of an attribute.
public int getAttributeCount() { return attributes.getAttributeCount(); } Gets the number of attributes that are defined.
public Enumeration getAttributeNames() { return attributes.getAttributeNames(); } Gets the names of all attributes.
public ChangeListener[] getChangeListeners() { return (ChangeListener[])listenerList.getListeners( ChangeListener.class); } Returns an array of all the ChangeListeners added to this NamedStyle with addChangeListener().
public T[] getListeners(Class listenerType) { return listenerList.getListeners(listenerType); } Return an array of all the listeners of the given type that were added to this model.
public String getName() { if (isDefined(StyleConstants.NameAttribute)) { return getAttribute(StyleConstants.NameAttribute).toString(); } return null; } Fetches the name of the style. A style is not required to be named, so null is returned if there is no name associated with the style.
public AttributeSet getResolveParent() { return attributes.getResolveParent(); } Gets attributes from the parent. If not overriden, the resolving parent defaults to the parent element.
public boolean isDefined(Object attrName) { return attributes.isDefined(attrName); } Checks whether a given attribute is defined.
public boolean isEqual(AttributeSet attr) { return attributes.isEqual(attr); } Checks whether two attribute sets are equal.
public void removeAttribute(Object name) { StyleContext context = StyleContext.this; attributes = context.removeAttribute(attributes, name); fireStateChanged(); } Removes an attribute from the set.
public void removeAttributes(Enumeration names) { StyleContext context = StyleContext.this; attributes = context.removeAttributes(attributes, names); fireStateChanged(); } Removes a set of attributes for the element.
public void removeAttributes(AttributeSet attrs) { StyleContext context = StyleContext.this; if (attrs == this) { attributes = context.getEmptySet(); } else { attributes = context.removeAttributes(attributes, attrs); } fireStateChanged(); } Removes a set of attributes for the element.
public void removeChangeListener(ChangeListener l) { listenerList.remove(ChangeListener.class, l); } Removes a change listener.
public void setName(String name) { if (name != null) { this.addAttribute(StyleConstants.NameAttribute, name); } } Changes the name of the style. Does nothing with a null name.
public void setResolveParent(AttributeSet parent) { if (parent != null) { addAttribute(StyleConstants.ResolveAttribute, parent); } else { removeAttribute(StyleConstants.ResolveAttribute); } } Sets the resolving parent.
public String toString() { return "NamedStyle:" + getName() + " " + attributes; } Converts the style to a string.
