Method Detail

values

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

Returns:

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

valueOf

public static UnaryOperator 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()

Returns the operator symbol.

Returns:

the operator symbol

getCategory

public UnaryOperator.Category getCategory()

Returns the operator category.

Returns:

the operator category

fromSymbol

public static UnaryOperator fromSymbol(String symbol)

Returns an operator from its symbol.

Parameters:

symbol - the target operator symbol

Returns:

the corresponded operator, or null if there is no such the operator

Throws:

IllegalArgumentException - if the parameter is null
