Method Detail

operator_and

@Pure
public static boolean operator_and(boolean a,
                                         boolean b)

The logical and (conjunction). This is the equivalent to the java && operator.

Parameters:

a - a boolean value.

b - another boolean value.

Returns:

a && b

operator_or

@Pure
public static boolean operator_or(boolean a,
                                        boolean b)

A logical or (disjunction). This is the equivalent to the java || operator.

Parameters:

a - a boolean value.

b - another boolean value.

Returns:

a || b

operator_not

@Pure
public static boolean operator_not(boolean b)

The logical not (negation). This is the equivalent to the java ! operator.

Parameters:

b - a boolean value.

Returns:

!b

operator_equals

@Pure
public static boolean operator_equals(boolean a,
                                            boolean b)

The binary equals operator. This is the equivalent to the java == operator.

Parameters:

a - an boolean.

b - an boolean.

Returns:

a==b

operator_notEquals

@Pure
public static boolean operator_notEquals(boolean a,
                                               boolean b)

The binary not equals operator. This is the equivalent to the java != operator.

Parameters:

a - an boolean.

b - an boolean.

Returns:

a!=b

xor

@Pure
public static boolean xor(boolean a,
                                boolean b)

A logical xor. This is the equivalent to the java ^ operator.

Parameters:

a - a boolean value.

b - another boolean value.

Returns:

a ^ b

operator_lessThan

@Pure
public static boolean operator_lessThan(boolean a,
                                              boolean b)

The binary lessThan operator for boolean values. false is considered less than true.

Parameters:

a - a boolean.

b - another boolean.

Returns:

Booleans.compare(a, b)<0

Since:

2.4

See Also:

Boolean.compareTo(Boolean), Booleans.compare(boolean, boolean)

operator_lessEqualsThan

@Pure
public static boolean operator_lessEqualsThan(boolean a,
                                                    boolean b)

The binary lessEqualsThan operator for boolean values. false is considered less than true.

Parameters:

a - a boolean.

b - another boolean.

Returns:

Booleans.compare(a, b)<=0

Since:

2.4

See Also:

Boolean.compareTo(Boolean), Booleans.compare(boolean, boolean)

operator_greaterThan

@Pure
public static boolean operator_greaterThan(boolean a,
                                                 boolean b)

The binary greaterThan operator for boolean values. false is considered less than true.

Parameters:

a - a boolean.

b - another boolean.

Returns:

Booleans.compare(a, b)>0

Since:

2.4

See Also:

Boolean.compareTo(Boolean), Booleans.compare(boolean, boolean)

operator_greaterEqualsThan

@Pure
public static boolean operator_greaterEqualsThan(boolean a,
                                                       boolean b)

The binary greaterEqualsThan operator for boolean values. false is considered less than true.

Parameters:

a - a boolean.

b - another boolean.

Returns:

Booleans.compare(a, b)>=0

Since:

2.4
