Method Detail

values

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

Returns:

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

valueOf

public static DataType 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

canBeCastedFromTo

public static boolean canBeCastedFromTo(DataType from,
                                        DataType to)

Checks if the DataType from can be casted to the DataType to without losing information. The following casts are allowed:

• BYTE -> BYTE, SHORT, INT, LONG, DOUBLE
• SHORT -> SHORT, INT, LONG, DOUBLE
• INT -> INT, LONG, DOUBLE
• LONG -> LONG
• DOUBLE -> DOUBLE

Parameters:

from - the DataType to cast from

to - the DataType to cast to

Returns:

true if the cast is possible, false otherwise
