OPEN_LOWER_BOUND

public static final BoundType OPEN_LOWER_BOUND

表示一个左开区间，等同于{x | x > a}

OPEN_UPPER_BOUND

public static final BoundType OPEN_UPPER_BOUND

表示一个右开区间，等同于{x | x < a}

Method Detail

values

public static BoundType[] 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 (BoundType c : BoundType.values())
    System.out.println(c);

Returns:

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

valueOf

public static BoundType 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

getSymbol

public String getSymbol()

获取符号

Returns:

符号

getCode

public int getCode()

getOperator

public String getOperator()

获取运算符

Returns:

isDislocated

public boolean isDislocated(BoundType boundType)
