Class StyleContext.SmallAttributeSet

java.lang.Object

javax.swing.text.StyleContext.SmallAttributeSet

All Implemented Interfaces:

AttributeSet

Enclosing class:

StyleContext

public class StyleContext.SmallAttributeSet
extends Object
implements AttributeSet

This class holds a small number of attributes in an array. The storage format is key, value, key, value, etc. The size of the set is the length of the array divided by two. By default, this is the class that will be used to store attributes when held in the compact shareable form.

Constructor Details

SmallAttributeSet

public SmallAttributeSet(Object[] attributes)

Constructs a SmallAttributeSet.

Parameters:

attributes - the attributes

SmallAttributeSet

public SmallAttributeSet(AttributeSet attrs)

Constructs a SmallAttributeSet.

Parameters:

attrs - the attributes

Method Details

toString

public String toString()

Returns a string showing the key/value pairs.

Overrides:

toString in class Object

Returns:

a string showing the key/value pairs

hashCode

public int hashCode()

Returns a hashcode for this set of attributes.

Overrides:

hashCode in class Object

Returns:

a hashcode value for this set of attributes.

See Also:

• Object.equals(java.lang.Object)
• System.identityHashCode(java.lang.Object)

equals

public boolean equals(Object obj)

Compares this object to the specified object. The result is true if the object is an equivalent set of attributes.

Overrides:

equals in class Object

Parameters:

obj - the object to compare with.

Returns:

true if the objects are equal; false otherwise.

See Also:

• Object.hashCode()
• HashMap

clone

public Object clone()

Clones a set of attributes. Since the set is immutable, a clone is basically the same set.

Overrides:

clone in class Object

Returns:

the set of attributes

See Also:

• Cloneable

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.

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.

Specified by:

getAttribute in interface AttributeSet

Parameters:

key - the attribute name

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()

Specified by:

getResolveParent in interface AttributeSet

Returns:

the attributes from the parent
