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

fromClass

public static DataType fromClass(Class inClass)

Since an Enum's valueOf() can't be overridden, this is our more flexible lookup.

Parameters:

inClass - the Class value for which the corresponding DataType will be returned

Returns:

the DataType corresponding to the specified Class value

fromString

public static DataType fromString(String inStringValue)

Since an Enum's valueOf() can't be overridden, this is our more flexible lookup.

Parameters:

inStringValue - the String value for which the corresponding DataType will be returned

Returns:

the DataType corresponding to the specified String value

isNumeric

public boolean isNumeric()

guessDataTypeFromValues

public static DataType guessDataTypeFromValues(Collection<? extends Object> inDataValues)
