Class BooleanVar

java.lang.Object

org.dmd.util.BooleanVar

public class BooleanVar
extends Object

The BooleanVar class provides for the storage of a boolean value that can be changed. This allows for a reference to a boolean to be passed and alterred. It also allows for the alteration of a boolean value object without having to create a new Boolean.

BooleanVar

public BooleanVar()

Creates a new BooleanVar with a value of false.

BooleanVar

public BooleanVar(boolean v)

Creates a new BooleanVar with the specified value.

BooleanVar

public BooleanVar(ResultSet rs,
                  String v)

Creates a new BooleanVar with the specified value.

Method Detail

copy

public BooleanVar copy()

Creates a deep copy of this object.

set

public void set(boolean v)

Sets the value as specified.

set

public boolean set(ResultSet rs,
                   String s)

Sets the value to true if the string is "true" and to false otherwise.

booleanValue

public boolean booleanValue()

Return the variable's value.

toString

public String toString()

Return the variable's value as a String.

Overrides:

toString in class Object

equals

public static boolean equals(boolean testVal,
                             Object obj)

Checks if the object is a BooleanVar that equals the test value and returns true if so. If the object is null and the test value if false, we return true i.e. the non-existence of the flag object equates to false.

If the object is not a BooleanVar, we return false.

equals

public boolean equals(Object obj)

Checks if the object is a BooleanVar that equals the test value and returns true if so. If the object is null or not a BooleanVar, we return false.

Overrides:

equals in class Object
