This class represents the OtherName as required by the GeneralNames ASN.1 object. It supplies the generic framework to allow specific Other Name types, and also provides minimal support for unrecognized Other Name types. The ASN.1 definition for OtherName is: 
OtherName ::= SEQUENCE {
    type-id    OBJECT IDENTIFIER,
    value      [0] EXPLICIT ANY DEFINED BY type-id
}

Method Summary

Modifier and TypeMethod and Description
public int

Returns:

constraint type above
constrains(GeneralNameInterface
to be checked for being constrained
inputName)

Implements sun.security.x509.GeneralNameInterface.constrains.

Return type of constraint inputName places on this name:

  • NAME_DIFF_TYPE = -1: input name is different type from name (i.e. does not constrain).
  • NAME_MATCH = 0: input name matches name.
  • NAME_NARROWS = 1: input name narrows name (is lower in the naming subtree)
  • NAME_WIDENS = 2: input name widens name (is higher in the naming subtree)
  • NAME_SAME_TYPE = 3: input name does not match or narrow name, but is same type.

Constructor Detail

OtherNameback to summary
public OtherName(ObjectIdentifier oid, byte[] value) throws IOException

Create the OtherName object from a passed ObjectIdentifier and byte array name value

Parameters
oid:ObjectIdentifier

ObjectIdentifier of this OtherName object

value:byte[]

the DER-encoded value of the OtherName

Exceptions

Method Detail

constrainsback to summary
public int constrains(GeneralNameInterface inputName)

Implements sun.security.x509.GeneralNameInterface.constrains.

Return type of constraint inputName places on this name:

  • NAME_DIFF_TYPE = -1: input name is different type from name (i.e. does not constrain).
  • NAME_MATCH = 0: input name matches name.
  • NAME_NARROWS = 1: input name narrows name (is lower in the naming subtree)
  • NAME_WIDENS = 2: input name widens name (is higher in the naming subtree)
  • NAME_SAME_TYPE = 3: input name does not match or narrow name, but is same type.
. These results are used in checking NameConstraints during certification path verification.
Parameters
inputName:GeneralNameInterface

to be checked for being constrained

Returns:int

constraint type above

Exceptions
UnsupportedOperationException:
if name is same type, but comparison operations are not supported for this name type.
encodeback to summary
public void encode(DerOutputStream out)

Implements sun.security.util.DerEncoder.encode.

Encode the Other name into the DerOutputStream.

Parameters
out:DerOutputStream

the DER stream to encode the Other-Name to.
