NAME

Net::LDAP::Intermediate - LDAPv3 intermediate response object base class

SYNOPSIS

 use Net::LDAP::Intermediate;

DESCRIPTION

"Net::LDAP::Intermediate" is a base-class for LDAPv3 intermediate response objects.

CONSTRUCTORS

new ( ARGS )

ARGS is a list of name/value pairs, valid arguments are:

responseName: A dotted-decimal representation of an OBJECT IDENTIFIER which uniquely identifies the intermediate response. This prevents conflicts between intermediate response names.
responseValue: Optional information associated with the intermediate response. It's format is specific to the particular intermediate response.

from_asn ( ASN )

ASN is a HASH reference, normally extracted from a PDU. It will contain a "responseName" element and optionally "responseValue" element. On return ASN will be blessed into a package. If "responseName" is a registered OID, then ASN will be blessed into the registered package, if not then ASN will be blessed into Net::LDAP::Intermediate.

This constructor is used internally by Net::LDAP and assumes that HASH passed contains a valid intermediate response. It should be used with caution.

METHODS

In addition to the methods listed below, each of the named parameters to "new" is also available as a method. "responseName" will return the OID of the intermediate response object. "responseValue" is set/get methods and will return the current value for each attribute if called without arguments, but may also be called with arguments to set new values.

error ()

If there has been an error returns a description of the error, otherwise it will return "undef"

init ()

"init" will be called as the last step in both constructors. What it does will depend on the sub-class. It must always return the object.

register ( OID )

"register" is provided for sub-class implementors. It should be called as a class method on a sub-class of Net::LDAP::Intermediate with the OID that the class will handle. Net::LDAP::Intermediate will remember this class and OID pair and use it in the following situations.

•: "new" is called as a class method on the Net::LDAP::Intermediate package and OID is passed as the responseName. The returned object will be blessed into the package that registered the OID.
•: "new" is called as a class method on a registered package and the "responseName" is not specified. The "responseName" will be set to the OID registered by that package.
•: "from_asn" is called to construct an object from ASN. The returned object will be blessed into the package which was registered to handle the OID in the ASN.

( to_asn )

Returns a structure suitable for passing to Convert::ASN1 for encoding. This method will be called by Net::LDAP when the intermediate response is used.

The base class implementation of this method will call the "responseValue" method without arguments to allow a sub-class to encode it's value. Sub-classes should not need to override this method.

valid ()

Returns true if the object is valid and can be encoded. The default implementation for this method is to return TRUE if there is no error, but sub-classes may override that.
