Java Source Code / Java Documentation » IDE Netbeans » openide » org.openide.util   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.openide.util.Union2 Union2 abstract public class Union2 implements Cloneable,Serializable(Code) A union type which can contain one of two kinds of objects. Object.equals and Object.hashCode treat this as a container, not identical to the contained object, but the identity is based on the contained object. The union is serialiable if its contained object is. Object.toString delegates to the contained object. author:    Jesse Glick since:    org.openide.util 7.1 Constructor Summary   Union2()      Method Summary abstract public  Union2<First, Second> clone()      public static  Union2<First, Second> createFirst(First first)      Construct a union based on the first type. public static  Union2<First, Second> createSecond(Second second)      Construct a union based on the second type. abstract public  First first()      Retrieve the union member of the first type. abstract public  boolean hasFirst()      Check if the union contains the first type. abstract public  boolean hasSecond()      Check if the union contains the second type. abstract public  Second second()      Retrieve the union member of the second type. Constructor Detail Union2 Union2()(Code) Method Detail clone abstract public Union2<First, Second> clone()(Code) createFirst public static Union2<First, Second> createFirst(First first)(Code) Construct a union based on the first type. Parameters:   first - an object of the first type a union containing that object createSecond public static Union2<First, Second> createSecond(Second second)(Code) Construct a union based on the second type. Parameters:   second - an object of the second type a union containing that object first abstract public First first() throws IllegalArgumentException(Code) Retrieve the union member of the first type. the object of the first type throws:   IllegalArgumentException - if the union really contains the second type hasFirst abstract public boolean hasFirst()(Code) Check if the union contains the first type. true if it contains the first type, false if it contains the second type hasSecond abstract public boolean hasSecond()(Code) Check if the union contains the second type. true if it contains the second type, false if it contains the first type second abstract public Second second() throws IllegalArgumentException(Code) Retrieve the union member of the second type. the object of the second type throws:   IllegalArgumentException - if the union really contains the first type Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
