All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ConditionResult>

public enum ConditionResult

extends java.lang.Enum<ConditionResult>

The result of a tri-state logical expression. Condition results are used to represent the result of a conditional evaluation that can yield three possible values: FALSE (i.e. "no"), TRUE (i.e. "yes"), or UNDEFINED (i.e. "maybe"). A result of UNDEFINED indicates that further investigation may be required.

Enum Constant Summary

FALSE
Indicates that the condition evaluated to false.

TRUE
Indicates that the condition evaluated to true.

UNDEFINED
Indicates that the condition could not be evaluated and its result is undefined.

Method Summary

static ConditionResult	and() Returns the logical AND of zero condition results, which is always TRUE.
static ConditionResult	and(ConditionResult... results) Returns the logical AND of the provided condition results, which is TRUE if all of the provided condition results are TRUE, FALSE if at least one of them is FALSE, and UNDEFINED otherwise.
static ConditionResult	and(ConditionResult r) Returns the logical AND of the provided condition result, which is always r.
static ConditionResult	and(ConditionResult r1, ConditionResult r2) Returns the logical AND of the provided condition results, which is TRUE if both of the provided condition results are TRUE, FALSE if at least one of them is FALSE , and UNDEFINED otherwise.
static ConditionResult	not(ConditionResult r) Returns the logical NOT of the provided condition result, which is TRUE if the provided condition result is FALSE, TRUE if it is FALSE, and UNDEFINED otherwise.
static ConditionResult	or() Returns the logical OR of zero condition results, which is always FALSE.
static ConditionResult	or(ConditionResult... results) Returns the logical OR of the provided condition results, which is FALSE if all of the provided condition results are FALSE, TRUE if at least one of them is TRUE, and UNDEFINED otherwise.
static ConditionResult	or(ConditionResult r) Returns the logical OR of the provided condition result, which is always r.
static ConditionResult	or(ConditionResult r1, ConditionResult r2) Returns the logical OR of the provided condition results, which is FALSE if both of the provided condition results are FALSE, TRUE if at least one of them is TRUE , and UNDEFINED otherwise.
boolean	toBoolean() Converts this condition result to a boolean value.
java.lang.String	toString() Returns the string representation of this condition result.
static ConditionResult	valueOf(boolean b) Returns the condition result which is equivalent to the provided boolean value.
static ConditionResult	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static ConditionResult[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

FALSE

public static final ConditionResult FALSE

Indicates that the condition evaluated to false.

UNDEFINED

public static final ConditionResult UNDEFINED

Indicates that the condition could not be evaluated and its result is undefined.

TRUE

public static final ConditionResult TRUE

Indicates that the condition evaluated to true.

Method Detail

values

public static ConditionResult[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ConditionResult c : ConditionResult.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ConditionResult valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

and

public static ConditionResult and()

Returns the logical AND of zero condition results, which is always TRUE.

Returns:

The logical OR of zero condition results, which is always TRUE.

and

public static ConditionResult and(ConditionResult r)

Returns the logical AND of the provided condition result, which is always r.

Parameters:

r - The condition result.

Returns:

The logical AND of the provided condition result, which is always r.

and

public static ConditionResult and(ConditionResult... results)

Returns the logical AND of the provided condition results, which is TRUE if all of the provided condition results are TRUE, FALSE if at least one of them is FALSE, and UNDEFINED otherwise. Note that TRUE is returned if the provided list of results is empty.

Parameters:

results - The condition results to be compared.

Returns:

The logical AND of the provided condition results.

and

public static ConditionResult and(ConditionResult r1,
                                  ConditionResult r2)

Returns the logical AND of the provided condition results, which is TRUE if both of the provided condition results are TRUE, FALSE if at least one of them is FALSE , and UNDEFINED otherwise.

Parameters:

r1 - The first condition result to be compared.

r2 - The second condition result to be compared.

Returns:

The logical AND of the provided condition results.

not

public static ConditionResult not(ConditionResult r)

Returns the logical NOT of the provided condition result, which is TRUE if the provided condition result is FALSE, TRUE if it is FALSE, and UNDEFINED otherwise.

Parameters:

r - The condition result to invert.

Returns:

The logical NOT of the provided condition result.

or

public static ConditionResult or()

Returns the logical OR of zero condition results, which is always FALSE.

Returns:

The logical OR of zero condition results, which is always FALSE.

or

public static ConditionResult or(ConditionResult r)

Returns the logical OR of the provided condition result, which is always r.

Parameters:

r - The condition result.

Returns:

The logical OR of the provided condition result, which is always r.

or

public static ConditionResult or(ConditionResult... results)

Returns the logical OR of the provided condition results, which is FALSE if all of the provided condition results are FALSE, TRUE if at least one of them is TRUE, and UNDEFINED otherwise. Note that FALSE is returned if the provided list of results is empty.

Parameters:

results - The condition results to be compared.

Returns:

The logical OR of the provided condition results.

or

public static ConditionResult or(ConditionResult r1,
                                 ConditionResult r2)

Returns the logical OR of the provided condition results, which is FALSE if both of the provided condition results are FALSE, TRUE if at least one of them is TRUE , and UNDEFINED otherwise.

Parameters:

r1 - The first condition result to be compared.

r2 - The second condition result to be compared.

Returns:

The logical OR of the provided condition results.

valueOf

public static ConditionResult valueOf(boolean b)

Returns the condition result which is equivalent to the provided boolean value.

Parameters:

b - The boolean value.

Returns:

TRUE if b was true, otherwise FALSE .

toBoolean

public boolean toBoolean()

Converts this condition result to a boolean value. FALSE and UNDEFINED are both converted to false, and TRUE is converted to true.
