Enum Constant Detail

STRING

public static final DataType STRING

a string value.

NUMERIC

public static final DataType NUMERIC

a numeric value.

BOOLEAN

public static final DataType BOOLEAN

a boolean value.

UNKNOWN

public static final DataType UNKNOWN

unknown type.

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

toDisplay

public String toDisplay()

Returns the display string.

Specified by:

toDisplay in interface EnumWithCustomDisplay<DataType>

Returns:

the display string

toRaw

public String toRaw()

Returns the raw enum string.

Specified by:

toRaw in interface EnumWithCustomDisplay<DataType>

Returns:

the raw enum string

toString

public String toString()

Returns the display string.

Overrides:

toString in class Enum<DataType>

Returns:

the display string

parse

public DataType parse(String s)

Parses the given string and returns the associated enum.

Specified by:

parse in interface EnumWithCustomParsing<DataType>

Parameters:

s - the string to parse

Returns:

the enum or null if not found

toString

public static String toString(AbstractOption option,
                              Object object)

Returns the enum as string.

Parameters:

option - the current option

object - the enum object to convert

Returns:

the generated string

valueOf

public static DataType valueOf(AbstractOption option,
                               String str)

Returns an enum generated from the string.

Parameters:

option - the current option

str - the string to convert to an enum

Returns:

the generated enum or null in case of error

guessType

public static DataType guessType(Object obj)

Guesses the data type from the object. In case of string, it checks for: boolean -> double -> string

Parameters:

obj - the object to inspect

Returns:

the data type
