RenderingHints

public RenderingHints(Map init)

Enabled: Constructs a new object with keys and values initialized from the specified Map object (which may be null).

Parameters:

init - a map of key/value pairs to initialize the hints or null if the object should be empty

---

RenderingHints

public RenderingHints(java.awt.RenderingHints.Key key,
 Object value)

Suppressed: Constructs a new object with the specified key/value pair.

Parameters:

key - the key of the particular hint property

value - the value of the hint property specified with key

size

public int size()

Suppressed: Returns the number of key-value mappings in this RenderingHints.

Specified by:

size in interface Map

Returns:

the number of key-value mappings in this RenderingHints.

---

isEmpty

public boolean isEmpty()

Suppressed: Returns true if this RenderingHints contains no key-value mappings.

Specified by:

isEmpty in interface Map

Returns:

true if this RenderingHints contains no key-value mappings.

---

containsKey

public boolean containsKey(Object key)

Suppressed: Returns true if this RenderingHints contains a mapping for the specified key.

Specified by:

containsKey in interface Map

Parameters:

key - key whose presence in this RenderingHints is to be tested.

Returns:

true if this RenderingHints contains a mapping for the specified key.

---

containsValue

public boolean containsValue(Object value)

Suppressed: Returns true if this RenderingHints maps one or more keys to the specified value. More formally, returns true if and only if this RenderingHints contains at least one mapping to a value v such that

 (value==null ? v==null : value.equals(v))
 

. This operation will probably require time linear in the RenderingHints size for most implementations of RenderingHints.

Specified by:

containsValue in interface Map

Parameters:

value - value whose presence in this RenderingHints is to be tested.

Returns:

true if this RenderingHints maps one or more keys to the specified value.

---

get

public Object get(Object key)

Suppressed: Returns the value to which the specified key is mapped.

Specified by:

get in interface Map

Parameters:

key - a rendering hint key

Returns:

the value to which the key is mapped in this object or null if the key is not mapped to any value in this object.

See Also:

put(Object, Object)

---

put

public Object put(Object key,
 Object value)

Suppressed: Maps the specified key to the specified value in this RenderingHints object. Neither the key nor the value can be null. The value can be retrieved by calling the get method with a key that is equal to the original key.

Specified by:

put in interface Map

Parameters:

key - the rendering hint key.

value - the rendering hint value.

Returns:

the previous value of the specified key in this object or null if it did not have one.

See Also:

get(Object)

---

add

public void add(RenderingHints hints)

Suppressed: Adds all of the keys and corresponding values from the specified RenderingHints object to this RenderingHints object. Keys that are present in this RenderingHints object, but not in the specified RenderingHints object are not affected.

Parameters:

hints - the set of key/value pairs to be added to this RenderingHints object

---

clear

public void clear()

Enabled: Clears this RenderingHints object of all key/value pairs.

Specified by:

clear in interface Map

---

remove

public Object remove(Object key)

Suppressed: Removes the key and its corresponding value from this RenderingHints object. This method does nothing if the key is not in this RenderingHints object.

Specified by:

remove in interface Map

Parameters:

key - the rendering hints key that needs to be removed

Returns:

the value to which the key had previously been mapped in this RenderingHints object, or null if the key did not have a mapping.

---

putAll

public void putAll(Map m)

Suppressed: Copies all of the mappings from the specified Map to this RenderingHints. These mappings replace any mappings that this RenderingHints had for any of the keys currently in the specified Map.

Specified by:

putAll in interface Map

Parameters:

m - the specified Map

---

keySet

public Set keySet()

Suppressed: Returns a Set view of the Keys contained in this RenderingHints. The Set is backed by the RenderingHints, so changes to the RenderingHints are reflected in the Set, and vice-versa. If the RenderingHints is modified while an iteration over the Set is in progress, the results of the iteration are undefined. The Set supports element removal, which removes the corresponding mapping from the RenderingHints, via the Iterator.remove, Set.remove, removeAll retainAll, and clear operations. It does not support the add or addAll operations.

Specified by:

keySet in interface Map

Returns:

a Set view of the keys contained in this RenderingHints.

---

values

public Collection values()

Suppressed: Returns a Collection view of the values contained in this RenderinHints. The Collection is backed by the RenderingHints, so changes to the RenderingHints are reflected in the Collection, and vice-versa. If the RenderingHints is modified while an iteration over the Collection is in progress, the results of the iteration are undefined. The Collection supports element removal, which removes the corresponding mapping from the RenderingHints, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:

values in interface Map

Returns:

a Collection view of the values contained in this RenderingHints.

---

entrySet

public Set entrySet()

Suppressed: Returns a Set view of the mappings contained in this RenderingHints. Each element in the returned Set is a Map.Entry. The Set is backed by the RenderingHints, so changes to the RenderingHints are reflected in the Set, and vice-versa. If the RenderingHints is modified while while an iteration over the Set is in progress, the results of the iteration are undefined.

The entrySet returned from a RenderingHints object is not modifiable.

Specified by:

entrySet in interface Map

Returns:

a Set view of the mappings contained in this RenderingHints.

---

equals

public boolean equals(Object o)

Suppressed: Compares the specified Object with this RenderingHints for equality. Returns true if the specified object is also a Map and the two Map objects represent the same mappings. More formally, two Map objects t1 and t2 represent the same mappings if t1.keySet().equals(t2.keySet()) and for every key k in t1.keySet(),

 (t1.get(k)==null ? t2.get(k)==null : t1.get(k).equals(t2.get(k)))
 

. This ensures that the equals method works properly across different implementations of the Map interface.

Specified by:

equals in interface Map

Overrides:

equals in class Object

Parameters:

o - Object to be compared for equality with this RenderingHints.

Returns:

true if the specified Object is equal to this RenderingHints.

---

hashCode

public int hashCode()

Suppressed: Returns the hash code value for this RenderingHints. The hash code of a RenderingHints is defined to be the sum of the hashCodes of each Entry in the RenderingHints object's entrySet view. This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two Map objects t1 and t2, as required by the general contract of Object.hashCode.

Specified by:

hashCode in interface Map

Overrides:

hashCode in class Object

Returns:

the hash code value for this RenderingHints.

See Also:

java.util.Map.Entry#hashCode(), Object.hashCode(), Object.equals(Object), equals(Object)

---

clone

public Object clone()

Suppressed: Creates a clone of this RenderingHints object that has the same contents as this RenderingHints object.

Overrides:

clone in class Object

Returns:

a clone of this instance.

See Also:

java.lang.Cloneable

---

toString

public String toString()

Suppressed: Returns a rather long string representation of the hashmap which contains the mappings of keys to values for this RenderingHints object.

Overrides:

toString in class Object

Returns:

a string representation of this object.
