Constructor Detail

MultiStyle

public MultiStyle(String n,
                  AttributeSet[] m)

Creates a new instance.

Parameters:

n - the name

m - the styles to multiplex

Method Detail

getName

public String getName()

Returns the name of the style.

Specified by:

getName in interface Style

Returns:

the name of the style

addChangeListener

public void addChangeListener(ChangeListener listener)

Description copied from interface: Style

Adds a ChangeListener object to the style.

Specified by:

addChangeListener in interface Style

Parameters:

listener - the listener object to add

removeChangeListener

public void removeChangeListener(ChangeListener listener)

Description copied from interface: Style

Removes a ChangeListener from to the style.

Specified by:

removeChangeListener in interface Style

Parameters:

listener - the listener object to remove,

addAttribute

public void addAttribute(Object name,
                         Object value)

Description copied from interface: MutableAttributeSet

Adds an attribute with the given name and value to the set. If the set already contains an attribute with the given name, the attribute value is updated.

Specified by:

addAttribute in interface MutableAttributeSet

Parameters:

name - the attribute name (null not permitted).

value - the value (null not permitted).

addAttributes

public void addAttributes(AttributeSet atts)

Description copied from interface: MutableAttributeSet

Adds all the attributes from attributes to this set.

Specified by:

addAttributes in interface MutableAttributeSet

Parameters:

atts - the set of attributes to add (null not permitted).

removeAttribute

public void removeAttribute(Object name)

Description copied from interface: MutableAttributeSet

Removes the attribute with the specified name, if this attribute is defined. This method will only remove an attribute from this set, not from the resolving parent.

Specified by:

removeAttribute in interface MutableAttributeSet

Parameters:

name - the attribute name (null not permitted).

removeAttributes

public void removeAttributes(Enumeration names)

Description copied from interface: MutableAttributeSet

Removes the attributes listed in names.

Specified by:

removeAttributes in interface MutableAttributeSet

Parameters:

names - the attribute names (null not permitted).

removeAttributes

public void removeAttributes(AttributeSet atts)

Description copied from interface: MutableAttributeSet

Removes attributes from this set if they are found in the given set. Only attributes whose key AND value are removed. Removes attributes only from this set, not from the resolving parent. Since the resolving parent is stored as an attribute, if attributes has the same resolving parent as this set, the parent will be removed from this set.

Specified by:

removeAttributes in interface MutableAttributeSet

Parameters:

atts - the attributes (null not permitted).

setResolveParent

public void setResolveParent(AttributeSet parent)

Description copied from interface: MutableAttributeSet

Sets the reolving parent for this set. When looking up an attribute, if it is not found in this set, then the resolving parent is also used for the lookup.

Specified by:

setResolveParent in interface MutableAttributeSet

Parameters:

parent - the parent attribute set (null not permitted).

containsAttribute

public boolean containsAttribute(Object name,
                                 Object value)

Description copied from interface: AttributeSet

Returns true if this AttributeSet contains an attribute with the specified name and value, false otherwise.

Specified by:

containsAttribute in interface AttributeSet

Parameters:

name - the name of the requested attribute

value - the value of the requested attribute

Returns:

true if this AttributeSet contains an attribute with the specified name and value, false otherwise

containsAttributes

public boolean containsAttributes(AttributeSet attributes)

Description copied from interface: AttributeSet

Returns true of this AttributeSet contains all of the specified attributes.

Specified by:

containsAttributes in interface AttributeSet

Parameters:

attributes - the requested attributes

Returns:

true of this AttributeSet contains all of the specified attributes

copyAttributes

public AttributeSet copyAttributes()

Description copied from interface: AttributeSet

Creates and returns a copy of this AttributeSet.

Specified by:

copyAttributes in interface AttributeSet

Returns:

a copy of this AttributeSet

getAttribute
