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

convertFromString

public abstract Object convertFromString(String input)

Convert a String to an DataType's expected value.

Parameters:

input - the string to convert

Returns:

the converted value

fromString

public static DataType fromString(String name)

Find a DataType by name

Parameters:

name - the name of the DataType

Returns:

the DataType or null

toString

public String toString()

Overrides:

toString in class Enum<DataType>
