Method Detail

values

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

Returns:

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

valueOf

public static Operator 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

writeTo

public void writeTo(java.io.DataOutput output)
             throws java.io.IOException

Write the serialized version of this Operator to the specified output.

Parameters:

output - the output to write to

Throws:

java.io.IOException - if an I/O problem occurs while writing to the specified output

readFrom

public static Operator readFrom(java.io.DataInput input)
                         throws java.io.IOException

Deserializes a Operator instance from the specified input.

Parameters:

input - the input to read from

Returns:

the Operator instance deserialized

Throws:

java.io.IOException - if a problem occurs while deserializing the Type instance.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<Operator>

reverse

public Operator reverse()

Returns the reverse operator if this one.

Returns:

the reverse operator of this one.
