HashAttributeSet JDK 1.6)

Constructors

public HashAttributeSet ()

Construct a new, empty attribute set.

public HashAttributeSet (Attribute attribute)

Construct a new attribute set, initially populated with the given attribute.

Construct a new attribute set,
initially populated with the given attribute.
Parameters:
- attribute - Attribute value to add to the set.
Throws:
- NullPointerException - (unchecked exception) Thrown if attribute is null.

public HashAttributeSet (Attribute attributes)

Construct a new attribute set, initially populated with the values from the given array.

Construct a new attribute set,
initially populated with the values from the
given array. The new attribute set is populated by
adding the elements of attributes array to the set in
sequence, starting at index 0. Thus, later array elements may replace
earlier array elements if the array contains duplicate attribute
values or attribute categories.
Parameters:
- attributes - Array of attribute values to add to the set. If null, an empty attribute set is constructed.
Throws:
- NullPointerException - (unchecked exception) Thrown if any element of attributes is null.

protected HashAttributeSet (Attribute attributes, Class<Object> interfaceName)

Construct a new attribute set, where the members of the attribute set are restricted to the given interface.

Construct a new attribute set, where the members of the attribute
set are restricted to the given interface.
The new attribute set is populated
by adding the elements of attributes array to the set in
sequence, starting at index 0. Thus, later array elements may replace
earlier array elements if the array contains duplicate attribute
values or attribute categories.
Parameters:
- attributes - Array of attribute values to add to the set. If null, an empty attribute set is constructed.
- interfaceName - The interface of which all members of this attribute set must be an instance. It is assumed to be interface {@link Attribute Attribute} or a subinterface thereof.
Throws:
- NullPointerException - (unchecked exception) Thrown if any element of attributes is null.
- NullPointerException - if interfaceName is null.
- ClassCastException - (unchecked exception) Thrown if any element of attributes is not an instance of interfaceName.

protected HashAttributeSet (Attribute attribute, Class<Object> interfaceName)

Construct a new attribute set, initially populated with the given attribute, where the members of the attribute set are restricted to the given interface.

Construct a new attribute set, initially populated with the given
attribute, where the members of the attribute set are restricted to the
given interface.
Parameters:
- attribute - Attribute value to add to the set.
- interfaceName - The interface of which all members of this attribute set must be an instance. It is assumed to be interface {@link Attribute Attribute} or a subinterface thereof.
Throws:
- NullPointerException - (unchecked exception) Thrown if attribute is null.
- NullPointerException - if interfaceName is null.
- ClassCastException - (unchecked exception) Thrown if attribute is not an instance of interfaceName.

public HashAttributeSet (AttributeSet attributes)

Construct a new attribute set, initially populated with the values from the given set.

protected HashAttributeSet (AttributeSet attributes, Class<Object> interfaceName)

Construct a new attribute set, initially populated with the values from the given set where the members of the attribute set are restricted to the given interface.

Construct a new attribute set, initially populated with the
values from the given set where the members of the attribute
set are restricted to the given interface.
Parameters:
- attributes - set of attribute values to initialise the set. If null, an empty attribute set is constructed.
- interfaceName - The interface of which all members of this attribute set must be an instance. It is assumed to be interface {@link Attribute Attribute} or a subinterface thereof.
Throws:
- ClassCastException - (unchecked exception) Thrown if any element of attributes is not an instance of interfaceName.

protected HashAttributeSet (Class<Object> interfaceName)

Construct a new, empty attribute set, where the members of the attribute set are restricted to the given interface.

Methods

Hide/Show inherited methods

public boolean add (Attribute attribute) [Specified in AttributeSet]

Adds the specified attribute to this attribute set if it is not already present, first removing any existing in the same attribute category as the specified attribute value.

Adds the specified attribute to this attribute set if it is not
already present, first removing any existing in the same
attribute category as the specified attribute value.
Returns: true if this attribute set changed as a result of the call, i.e., the given attribute value was not already a member of this attribute set.
Parameters:
- attribute - Attribute value to be added to this attribute set.
Throws:
- NullPointerException - (unchecked exception) Thrown if the attribute is null.
- UnmodifiableSetException - (unchecked exception) Thrown if this attribute set does not support the add() operation.

public boolean addAll (AttributeSet attributes) [Specified in AttributeSet]

Adds all of the elements in the specified set to this attribute.

Adds all of the elements in the specified set to this attribute. The outcome is the same as if the add(Attribute) operation had been applied to this attribute set successively with each element from the specified set. The behavior of the addAll(AttributeSet) operation is unspecified if the specified set is modified while the operation is in progress.

If the addAll(AttributeSet) operation throws an exception, the effect on this attribute set's state is implementation dependent; elements from the specified set before the point of the exception may or may not have been added to this attribute set.
Returns: true if this attribute set changed as a result of the call.
Parameters:
- attributes - whose elements are to be added to this attribute set.
Throws:
- UnmodifiableSetException - (Unchecked exception) Thrown if this attribute set does not support the addAll(AttributeSet) method.
- NullPointerException - (Unchecked exception) Thrown if some element in the specified set is null, or the set is null.

public void clear () [Specified in AttributeSet]

Removes all attributes from this attribute set.

Removes all attributes from this attribute set.
Throws:
- UnmodifiableSetException - (unchecked exception) Thrown if this attribute set does not support the clear() operation.

public boolean containsKey (Class<Object> category) [Specified in AttributeSet]

Returns true if this attribute set contains an attribute for the specified category.

public boolean containsValue (Attribute attribute) [Specified in AttributeSet]

Returns true if this attribute set contains the given attribute.

public boolean equals (Object object) [Specified in AttributeSet]

Compares the specified object with this attribute set for equality.

public Attribute get (Class<Object> category) [Specified in AttributeSet]

Returns the attribute value which this attribute set contains in the given attribute category.

Returns the attribute value which this attribute set contains in the
given attribute category. Returns null if this attribute set
does not contain any attribute value in the given attribute category.
Returns: The attribute value in the given attribute category contained in this attribute set, or null if this attribute set does not contain any attribute value in the given attribute category.
Parameters:
- category - Attribute category whose associated attribute value is to be returned. It must be a {@link java.lang.Class Class} that implements interface {@link Attribute Attribute}.
Throws:
- NullPointerException - (unchecked exception) Thrown if the category is null.
- ClassCastException - (unchecked exception) Thrown if the category is not a {@link java.lang.Class Class} that implements interface {@link Attribute Attribute}.

Returns the hash code value for this attribute set.

public boolean isEmpty () [Specified in AttributeSet]

Returns true if this attribute set contains no attributes.

public boolean remove (Attribute attribute) [Specified in AttributeSet]

Removes the specified attribute from this attribute set if present.

Removes the specified attribute from this attribute set if
present. If attribute is null, then
remove() does nothing and returns false.
Returns: true if this attribute set changed as a result of the call, i.e., the given attribute value had been a member of this attribute set.
Parameters:
