Method Detail

values

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

Returns:

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

valueOf

public static ExtensionType 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

fromOid

public static ExtensionType fromOid(String oid)

Gets the extension by OID.

Parameters:

oid - Extension OID value.

Returns:

Extension with given OID value.

Throws:

IllegalArgumentException - If no extension with given OID exists.

fromName

public static ExtensionType fromName(String name)

Gets the extension by name.

Parameters:

name - Case-sensitive X.509v3 extension name. The acceptable case of extension names is governed by conventions in RFC 2459.

Returns:

Extension with given name.

Throws:

IllegalArgumentException - If no extension with given name exists.

isCritical

public boolean isCritical()

Returns:

True if extension MUST or SHOULD be marked critical under general circumstances according to RFC 2459, false otherwise.

getOid

public String getOid()

Returns:

OID value of extension field.
