All Implemented Interfaces:

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

public enum Type
extends java.lang.Enum<Type>

Class representing a type in SimpleDB. Types are static objects defined by this class; hence, the Type constructor is private.

Method Detail

values

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

Returns:

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

valueOf

public static Type 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

getLen

public abstract int getLen()

Returns:

the number of bytes required to store a field of this type.

parse

public abstract Field parse(java.io.DataInputStream dis)
                     throws java.text.ParseException

Parameters:

dis - The input stream to read from

Returns:

a Field object of the same type as this object that has contents read from the specified DataInputStream.

Throws:

java.text.ParseException - if the data read from the input stream is not of the appropriate type.
