org.apache.drill.common.types.BooleanType

All Implemented Interfaces:

Serializable, Comparable<BooleanType>

public enum BooleanType
extends Enum<BooleanType>

Enum that contains two boolean types: TRUE and FALSE. Each has numeric representation and list of allowed literals. List of literals if formed according to {@link <a href="https://www.postgresql.org/docs/9.6/static/datatype-boolean.html">Postgre Documentation}

Method Summary

Modifier and Type	Method	Description
static boolean	fromString(String value)	Runtime form of Boolean conversion: allows any of the valid "true" values; assumes all other values are false.
static BooleanType	get(String literal)	Finds boolean by passed literal.
String[]	getLiterals()
int	getNumericValue()
static BooleanType	valueOf(String name)	Returns the enum constant of this type with the specified name.
static BooleanType[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Details

values

public static BooleanType[] values()

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

Returns:

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

valueOf

public static BooleanType valueOf(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:

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

NullPointerException - if the argument is null

getNumericValue

public int getNumericValue()

getLiterals

public String[] getLiterals()

get

public static BooleanType get(String literal)

Finds boolean by passed literal. Leading or trailing whitespace is ignored, and case does not matter.

Parameters:

literal - boolean string representation

Returns:

boolean type

Throws:

IllegalArgumentException - if boolean type is not found

fromString

public static boolean fromString(String value)

Runtime form of Boolean conversion: allows any of the valid "true" values; assumes all other values are false. Does case-insensitive comparisons. If the string must be trimmed, the caller should do it.

Parameters:

value - non-null string value

Returns:

true (if one of the TRUE literals), else false
