One cell numeric or String based DataType

FRAME

public static final Types.DataType FRAME

Two or One Dimensional heterogeneous DataType

LIST

public static final Types.DataType LIST

List primitive able to contain any other DataType at indexes

Method Detail

values

public static Types.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 (Types.DataType c : Types.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 Types.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
