Field Detail

attrs

private AttributeSet[] attrs

The AttributeSets that make up the resulting AttributeSet.

Constructor Detail

MuxingAttributeSet

public MuxingAttributeSet(AttributeSet[] attrs)

Creates a MuxingAttributeSet with the passed in attributes.

MuxingAttributeSet

protected MuxingAttributeSet()

Creates an empty MuxingAttributeSet. This is intended for use by subclasses only, and it is also intended that subclasses will set the constituent AttributeSets before invoking any of the AttributeSet methods.

Method Detail

setAttributes

protected void setAttributes(AttributeSet[] attrs)

Directly sets the AttributeSets that comprise this MuxingAttributeSet.

getAttributes

protected AttributeSet[] getAttributes()

Returns the AttributeSets multiplexing too. When the AttributeSets need to be referenced, this should be called.

insertAttributeSetAt

protected void insertAttributeSetAt(AttributeSet as,
                                    int index)

Inserts as at index. This assumes the value of index is between 0 and attrs.length, inclusive.

removeAttributeSetAt

protected void removeAttributeSetAt(int index)

Removes the AttributeSet at index. This assumes the value of index is greater than or equal to 0, and less than attrs.length.

getAttributeCount

public int getAttributeCount()

Gets the number of attributes that are defined.

Specified by:

getAttributeCount in interface AttributeSet

Returns:

the number of attributes

See Also:

AttributeSet.getAttributeCount()

isDefined

public boolean isDefined(Object key)

Checks whether a given attribute is defined. This will convert the key over to CSS if the key is a StyleConstants key that has a CSS mapping.

Specified by:

isDefined in interface AttributeSet

Parameters:

key - the attribute key

Returns:

true if the attribute is defined

See Also:

AttributeSet.isDefined(java.lang.Object)

isEqual

public boolean isEqual(AttributeSet attr)

Checks whether two attribute sets are equal.

Specified by:

isEqual in interface AttributeSet

Parameters:

attr - the attribute set to check against

Returns:

true if the same

See Also:

AttributeSet.isEqual(javax.swing.text.AttributeSet)

copyAttributes

public AttributeSet copyAttributes()

Copies a set of attributes.

Specified by:

copyAttributes in interface AttributeSet

Returns:

the copy

See Also:

AttributeSet.copyAttributes()

getAttribute

public Object getAttribute(Object key)

Gets the value of an attribute. If the requested attribute is a StyleConstants attribute that has a CSS mapping, the request will be converted.

Specified by:

getAttribute in interface AttributeSet

Parameters:

key - the attribute name

Returns:

the attribute value

See Also:

AttributeSet.getAttribute(java.lang.Object)

getAttributeNames

public Enumeration getAttributeNames()

Gets the names of all attributes.

Specified by:

getAttributeNames in interface AttributeSet

Returns:

the attribute names

See Also:

AttributeSet.getAttributeNames()

containsAttribute

public boolean containsAttribute(Object name,
                                 Object value)

Checks whether a given attribute name/value is defined.

Specified by:

containsAttribute in interface AttributeSet

Parameters:

name - the attribute name

value - the attribute value

Returns:

true if the name/value is defined

See Also:

AttributeSet.containsAttribute(java.lang.Object, java.lang.Object)

containsAttributes

public boolean containsAttributes(AttributeSet attrs)

Checks whether the attribute set contains all of the given attributes.

Specified by:

containsAttributes in interface AttributeSet

Parameters:

attrs - the attributes to check

Returns:

true if the element contains all the attributes

See Also:

AttributeSet.containsAttributes(javax.swing.text.AttributeSet)

getResolveParent

public AttributeSet getResolveParent()

Returns null, subclasses may wish to do something more intelligent with this.

Specified by:

getResolveParent in interface AttributeSet

Returns:

the parent
