Class bits 00 — universally defined tag.

APPLICATION

public static final TLVClass APPLICATION

Class bits 01 — application-specific tag.

Method Details

values

public static TLVClass[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static TLVClass valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

valueOf

public static TLVClass valueOf(byte firstByte)

Resolves the TLVClass encoded in the top two bits of firstByte.

Parameters:

firstByte - the first byte of a BER-TLV tag

Returns:

the matching class, defaulting to UNIVERSAL
