Enum Constant Detail

V10

public static final TapVersion V10

TAP version 1.0.

V11

public static final TapVersion V11

TAP version 1.1.

Method Detail

values

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

Returns:

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

valueOf

public static TapVersion 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

getNumber

public String getNumber()

Returns a numeric text string corresponding to this version.

Returns:

numeric string, for instance "1.0"

is11

public boolean is11()

True if this version is greater than or equal to TAP version 1.1.

Returns:

true for v1.1+

fromString

public static TapVersion fromString(String txt)

Returns the best guess at a defined TapVersion value for a given version string. "1.1" maps to V11 and "1.0" (as well as most other things) map to V10.

TAP 1.1 sec 2.4 says "clients should treat a missing version attribute as equivalent to version='1.0'."

Parameters:

txt - version string, may be null

Returns:

TapVersion instance, not null

toString

public String toString()

Overrides:

toString in class Enum<TapVersion>
