public interface AttributeSet

A set of attributes. An attribute has a key and a value. They typically describe features of a piece of text that make up its graphical representation. An AttributeSet may have a resolving parent, that is another AttributeSet that is searched for attribute keys that are not stored locally in this AttributeSet.

Nested Class Summary
`static interface`	`AttributeSet.CharacterAttribute` Used as keys to identify character-run attributes.
`static interface`	`AttributeSet.ColorAttribute` Used as keys to identify color attributes.
`static interface`	`AttributeSet.FontAttribute` Used as keys to identify font attributes.
`static interface`	`AttributeSet.ParagraphAttribute` Used as keys to identify paragraph level attributes.

Field Summary
`static Object`	`NameAttribute` Key of the attribute that is used to describe the name of an `AttributeSet`.
`static Object`	`ResolveAttribute` Key of the attribute that is used to identify the resolving parent of an `AttributeSet`.

Method Summary
`boolean`	`containsAttribute(Object name, Object value)` Returns `true` if this `AttributeSet` contains an attribute with the specified `name` and `value`, `false` otherwise.
`boolean`	`containsAttributes(AttributeSet attributes)` Returns `true` of this `AttributeSet` contains all of the specified `attributes`.
`AttributeSet`	`copyAttributes()` Creates and returns a copy of this `AttributeSet`.
`Object`	`getAttribute(Object key)` Returns the attribute with the specified `key` or `null` if no such attribute is defined in this `AttributeSet` and its resolving parents.
`int`	`getAttributeCount()` Returns the number of attributes that are stored locally in this `AttributeSet`.
`Enumeration`	`getAttributeNames()` Returns the names of the attributes that are stored in this `AttributeSet`.
`AttributeSet`	`getResolveParent()` Returns the resolving parent of this `AttributeSet`.
`boolean`	`isDefined(Object attrName)` Returns `true` if an attribute with the specified name is defined locally in this `AttributeSet`, without resolving through the resolving parents.
`boolean`	`isEqual(AttributeSet attr)` Returns `true` if all of the attributes in `attr` are equal to the attributes in this `AttributeSet`, `false` otherwise.

NameAttribute

public static final Object NameAttribute

Key of the attribute that is used to describe the name of an AttributeSet.

ResolveAttribute

public static final Object ResolveAttribute

Key of the attribute that is used to identify the resolving parent of an AttributeSet.

containsAttribute

public boolean containsAttribute(Object name,
                                 Object value)

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

Returns true of this AttributeSet contains all of the specified attributes.
Parameters:
attributes - the requested attributes
Returns:
true of this AttributeSet contains all of the specified attributes

copyAttributes

public AttributeSet copyAttributes()

Creates and returns a copy of this AttributeSet.
Returns:
a copy of this AttributeSet

getAttribute

public Object getAttribute(Object key)

Returns the attribute with the specified key or null if no such attribute is defined in this AttributeSet and its resolving parents.
Parameters:
key - the key of the attribute that is looked up
Returns:
the attribute with the specified key or null if no such attribute is defined in this AttributeSet and its resolving parents

getAttributeCount

public int getAttributeCount()

Returns the number of attributes that are stored locally in this AttributeSet.
Returns:
the number of attributes that are stored locally in this AttributeSet

getAttributeNames

public Enumeration getAttributeNames()

Returns the names of the attributes that are stored in this AttributeSet.
Returns:
the names of the attributes that are stored in this AttributeSet

getResolveParent

public AttributeSet getResolveParent()

Returns the resolving parent of this AttributeSet. If a key is not stored locally, then a getAttribute(Object) request is resolved up in the resolving parent of this AttributeSet.
Returns:
the resolving parent of this AttributeSet

isDefined

public boolean isDefined(Object attrName)

Returns true if an attribute with the specified name is defined locally in this AttributeSet, without resolving through the resolving parents.
Returns:
true if an attribute with the specified name is defined locally in this AttributeSet

isEqual

public boolean isEqual(AttributeSet attr)

Returns true if all of the attributes in attr are equal to the attributes in this AttributeSet, false otherwise.
Parameters:
attr - the attributes to be compared to this
Returns:
true if all of the attributes in attr are equal to the attributes in this AttributeSet, false otherwise
