Constructor Summary

RenderingHints (Map <RenderingHints.Key ,?> init)
Constructs a new object with keys and values initialized from the specified Map object (which may be null).

RenderingHints (RenderingHints.Key key, Object value)
Constructs a new object with the specified key/value pair.

Method Summary

void	add (RenderingHints hints) Adds all of the keys and corresponding values from the specified RenderingHints object to this RenderingHints object.
void	clear () Clears this RenderingHints object of all key/value pairs.
Object	clone () Creates a clone of this RenderingHints object that has the same contents as this RenderingHints object.
boolean	containsKey (Object key) Returns true if this RenderingHints contains a mapping for the specified key.
boolean	containsValue (Object value) Returns true if this RenderingHints maps one or more keys to the specified value.
Set <Map.Entry <Object ,Object >>	entrySet () Returns a Set view of the mappings contained in this RenderingHints.
boolean	equals (Object o) Compares the specified Object with this RenderingHints for equality.
Object	get (Object key) Returns the value to which the specified key is mapped.
int	hashCode () Returns the hash code value for this RenderingHints.
boolean	isEmpty () Returns true if this RenderingHints contains no key-value mappings.
Set <Object >	keySet () Returns a Set view of the Keys contained in this RenderingHints.
Object	put (Object key, Object value) Maps the specified key to the specified value in this RenderingHints object.
void	putAll (Map <?,?> m) Copies all of the mappings from the specified Map to this RenderingHints.
Object	remove (Object key) Removes the key and its corresponding value from this RenderingHints object.
int	size () Returns the number of key-value mappings in this RenderingHints.
String	toString () Returns a rather long string representation of the hashmap which contains the mappings of keys to values for this RenderingHints object.
Collection <Object >	values () Returns a Collection view of the values contained in this RenderinHints.
