Method Detail

values

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

Returns:

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

valueOf

public static InstallationUtil.FrameworkVersion 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

isCompatibleTo

public boolean isCompatibleTo(InstallationUtil.FrameworkVersion running)

Returns whether or not this version is compatible to the specified running version.

Parameters:

running - the running version

Returns:

true if it is compatible for this version, otherwise false

find

public static InstallationUtil.FrameworkVersion find(String name)

Returns a version constant from its name.

Parameters:

name - the version name

Returns:

the related version, or null if there is no such a version

get

public static InstallationUtil.FrameworkVersion get()

Returns the currently linked framework version.

Returns:

the currently linked version

toString

public String toString()

Overrides:

toString in class Enum<InstallationUtil.FrameworkVersion>
