javax.swing.text.AttributeSet — clojure-interop/javax.swing 1.0.5

A collection of unique attributes. This is a read-only, immutable interface. An attribute is basically a key and a value assigned to the key. The collection may represent something like a style run, a logical style, etc. These are generally used to describe features that will contribute to some graphical representation such as a font. The set of possible keys is unbounded and can be anything. Typically View implementations will respond to attribute definitions and render something to represent the attributes.

Attributes can potentially resolve in a hierarchy. If a key doesn't resolve locally, and a resolving parent exists, the key will be resolved through the parent.

contains-attribute clj

(contains-attribute this name value)

Returns true if this set defines an attribute with the same name and an equal value. If such an attribute is not found locally, it is searched through in the resolving parent hierarchy.

name - the non-null attribute name - java.lang.Object value - the value - java.lang.Object

returns: true if the set defines the attribute with an equal value, either locally or through its resolving parent - boolean

throws: java.lang.NullPointerException - if either name or value is null

contains-attributes clj

(contains-attributes this attributes)

Returns true if this set defines all the attributes from the given set with equal values. If an attribute is not found locally, it is searched through in the resolving parent hierarchy.

attributes - the set of attributes to check against - javax.swing.text.AttributeSet

returns: true if this set defines all the attributes with equal values, either locally or through its resolving parent - boolean

throws: java.lang.NullPointerException - if attributes is null

copy-attributes clj

(copy-attributes this)

Returns an attribute set that is guaranteed not to change over time.

returns: a copy of the attribute set - javax.swing.text.AttributeSet

defined? clj

(defined? this attr-name)

Checks whether the named attribute has a value specified in the set without resolving through another attribute set.

attr-name - the attribute name - java.lang.Object

returns: true if the attribute has a value specified - boolean

equal? clj

(equal? this attr)

Determines if the two attribute sets are equivalent.

attr - an attribute set - javax.swing.text.AttributeSet

returns: true if the sets are equivalent - boolean

get-attribute clj

(get-attribute this key)

Fetches the value of the given attribute. If the value is not found locally, the search is continued upward through the resolving parent (if one exists) until the value is either found or there are no more parents. If the value is not found, null is returned.

key - the non-null key of the attribute binding - java.lang.Object

returns: the value of the attribute, or null if not found - java.lang.Object

get-attribute-count clj

(get-attribute-count this)

Returns the number of attributes that are defined locally in this set. Attributes that are defined in the parent set are not included.

returns: the number of attributes >= 0 - int

get-attribute-names clj

(get-attribute-names this)

Returns an enumeration over the names of the attributes that are defined locally in the set. Names of attributes defined in the resolving parent, if any, are not included. The values of the Enumeration may be anything and are not constrained to a particular Object type.

This method never returns null. For a set with no attributes, it returns an empty Enumeration.

returns: the names - java.util.Enumeration<?>

get-resolve-parent clj

(get-resolve-parent this)

Gets the resolving parent.

returns: the parent - javax.swing.text.AttributeSet
