Class BooleanOperations

io.cui.tools.base.BooleanOperations

public final class BooleanOperations
extends Object

Utility Class providing some boolean operations. In essence, it simplifies 'or' and 'and' operations. Some examples from the unit-tests:

 @Test
 void shouldDetectAnyTrue() {
     assertTrue(BooleanOperations.isAnyTrue(true));
     assertTrue(BooleanOperations.isAnyTrue(true, true));
     assertTrue(BooleanOperations.isAnyTrue(true, false));
     assertFalse(BooleanOperations.isAnyTrue(false, false));
     // Not really sensible, but defined contract -> Corner Case
     assertFalse(BooleanOperations.isAnyTrue());
     assertFalse(BooleanOperations.isAnyTrue(null));
 }

 @Test
 void shouldDetectAnyFalse() {
     assertFalse(BooleanOperations.isAnyFalse(true));
     assertTrue(BooleanOperations.isAnyFalse(true, false));
     assertTrue(BooleanOperations.isAnyFalse(false, false));
     // Not really sensible, but defined contract -> Corner Case
     assertFalse(BooleanOperations.isAnyFalse());
     assertFalse(BooleanOperations.isAnyFalse(null));
 }

 @Test
 void shouldDetectAllFalse() {
     assertFalse(BooleanOperations.areAllFalse(true));
     assertFalse(BooleanOperations.areAllFalse(true, false));
     assertFalse(BooleanOperations.areAllFalse(true, true));
     assertTrue(BooleanOperations.areAllFalse(false, false));
     // Not really sensible, but defined contract -> Corner Case
     assertFalse(BooleanOperations.areAllFalse());
     assertFalse(BooleanOperations.areAllFalse(null));
 }

 @Test
 void shouldDetectAllTrue() {
     assertTrue(BooleanOperations.areAllTrue(true));
     assertFalse(BooleanOperations.areAllTrue(true, false));
     assertTrue(BooleanOperations.areAllTrue(true, true));
     assertFalse(BooleanOperations.areAllTrue(false, false));
     // Not really sensible, but defined contract -> Corner Case
     assertTrue(BooleanOperations.areAllTrue());
     assertTrue(BooleanOperations.areAllTrue(null));
 }

Method Detail

isAnyTrue

public static boolean isAnyTrue(boolean... parameter)

Shorthand for checking if at least one of the given booleans is true

Parameters:

parameter - ellipsis of boolean values

Returns:

true if one of parameters is true, false otherwise

areAllTrue

public static boolean areAllTrue(boolean... parameter)

Shorthand for checking if all the given booleans are true

Parameters:

parameter - ellipsis of boolean values

Returns:

true if all parameters are true or no parameter is given ratio: no given false, false otherwise

areAllFalse

public static boolean areAllFalse(boolean... parameter)

Shorthand for checking if all given booleans are false

Parameters:

parameter - ellipsis of boolean values

Returns:

true if all parameters are false, true otherwise. false if no parameter is passed, ratio: no given false

isAnyFalse

public static boolean isAnyFalse(boolean... parameter)

Shorthand for checking if at least one of the given booleans is false

Parameters:

parameter - ellipsis of boolean values

Returns:

true if one of parameters is false, true otherwise

isValidBoolean

public static boolean isValidBoolean(String value)

Parameters:

value - to be checked

Returns:

true, if the given value represents a boolean value i.e. "true" or "false" ignoring case.
