Subset
class Subset
Instances of this class represent particular subsets of the Unicode character set. The only family of subsets defined in the Character class is Character.UnicodeBlock. Other portions of the Java API may define other subsets for their own purposes.
Summary
| Protected constructors |
|
Constructs a new Subset instance.
|
| Public methods |
| Boolean |
Compares two Subset objects for equality.
|
| Int |
Returns the standard hash code as defined by the Object.hashCode method.
|
| String |
Returns the name of this subset.
|
Protected constructors
Subset
protected Subset(name: String)
Constructs a new Subset instance.
| Parameters |
name |
String: The name of this subset |
| Exceptions |
java.lang.NullPointerException |
if name is null |
Public methods
equals
fun equals(other: Any?): Boolean
Compares two Subset objects for equality. This method returns true if and only if this and the argument refer to the same object; since this method is final, this guarantee holds for all subclasses.
| Parameters |
obj |
the reference object with which to compare. |
| Return |
Boolean |
true if this object is the same as the obj argument; false otherwise. |
hashCode
fun hashCode(): Int
Returns the standard hash code as defined by the Object.hashCode method. This method is final in order to ensure that the equals and hashCode methods will be consistent in all subclasses.
| Return |
Int |
a hash code value for this object. |
toString
fun toString(): String
Returns the name of this subset.
| Return |
String |
a string representation of the object. |
