Method Detail

values

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

Returns:

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

valueOf

public static JavaVersion valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

parse

public static JavaVersion parse(java.lang.String str)

Parses a Java version string.

Parameters:

str - The version string.

Returns:

The JavaVersion. UNKNOWN if a version could be found but could not be identified. null if one could not be identified.

parseFromClass

public static JavaVersion parseFromClass(byte[] bytes)

Parses the Java version from a binary class file.

Parameters:

bytes - The class file bytes.

Returns:

The JavaVersion.

parseFromClass

public static JavaVersion parseFromClass(int version)

Parses the Java version from the version attribute of a class file.

This can be obtained via a library such as ObjectWeb ASM.

Parameters:

version - The version.

Returns:

The JavaVersion
