NAME

       fixed - the corba fixed type

DESCRIPTION

       This module contains functions that gives an interface to the CORBA fixed type.

       The type Fixed used below is defined as:

	     -record(fixed, {digits, scale, value}).

       where digits is the total amount of digits it consists of and scale is the number of fractional digits. The value field contains the actual
       Fixed value represented as an integer. The limitations of each field are:

	 * Digits - integer(), -1 > Digits < 32

	 * Scale - integer(), -1 > Scale =< Digits

	 * Value - integer(), range (31 digits): +/-9999999999999999999999999999999

       Since the Value part is represented by an integer, it is vital that the Digits and Scale values are correct. This also means that  trailing
       zeros cannot be left out in some cases:

	 * fixed<5,3> eq. 03.140d eq. 3140

	 * fixed<3,2> eq. 3.14d eq. 314

       Leading zeros can be left out.

       For your convenience, this module exports functions which handle unary ( - ) and binary ( +-*/ ) operations legal for the Fixed type. Since
       a unary + have no effect, this module do not export such a function. Any of the binary operations may cause an overflow (i.e. more than	31
       significant  digits;  leading  and  trailing  zeros  are  not  considered significant). If this is the case, the Digit and Scale values are
       adjusted and the Value truncated (no rounding performed). This behavior is compliant with the OMG CORBA specification. Each  binary  opera-
       tion have the following upper bounds:

	 * Fixed1 + Fixed2 - fixed<max(d1-s1,d2-s2) + max(s1,s2) + 1, max(s1,s2)>

	 * Fixed1 - Fixed2 - fixed<max(d1-s1,d2-s2) + max(s1,s2) + 1, max(s1,s2)>

	 * Fixed1 * Fixed2 - fixed<d1+d2, s1+s2>

	 * Fixed1 / Fixed2 - fixed<(d1-s1+s2) + Sinf ,Sinf >

       A quotient may have an arbitrary number of decimal places, which is denoted by a scale of Sinf.

EXPORTS

       create(Digits, Scale, Value) -> Result

	      Types  Result = Fixed Type | {'EXCEPTION', #'BAD_PARAM'{}}

	      This function creates a new instance of a Fixed Type . If the limitations is not fulfilled (e.g. overflow) an exception is raised.

       get_typecode(Fixed) -> Result

	      Types  Result = TypeCode | {'EXCEPTION', #'BAD_PARAM'{}}

	      Returns the TypeCode which represents the supplied Fixed type. If the parameter is not of the correct type, an exception is raised.

       add(Fixed1, Fixed2) -> Result

	      Types  Result = Fixed1 + Fixed2 | {'EXCEPTION', #'BAD_PARAM'{}}

	      Performs a Fixed type addition. If the parameters are not of the correct type, an exception is raised.

       subtract(Fixed1, Fixed2) -> Result

	      Types  Result = Fixed1 - Fixed2 | {'EXCEPTION', #'BAD_PARAM'{}}

	      Performs a Fixed type subtraction. If the parameters are not of the correct type, an exception is raised.

       multiply(Fixed1, Fixed2) -> Result

	      Types  Result = Fixed1 * Fixed2 | {'EXCEPTION', #'BAD_PARAM'{}}

	      Performs a Fixed type multiplication. If the parameters are not of the correct type, an exception is raised.

       divide(Fixed1, Fixed2) -> Result

	      Types  Result = Fixed1 / Fixed2 | {'EXCEPTION', #'BAD_PARAM'{}}

	      Performs a Fixed type division. If the parameters are not of the correct type, an exception is raised.

       unary_minus(Fixed) -> Result

	      Types  Result = -Fixed | {'EXCEPTION', #'BAD_PARAM'{}}

	      Negates the supplied Fixed type. If the parameter is not of the correct type, an exception is raised.

CosNotifyChannelAdmin_SequenceProxyPushSupplier(3erl)	     Erlang Module Definition	     CosNotifyChannelAdmin_SequenceProxyPushSupplier(3erl)

NAME

       CosNotifyChannelAdmin_SequenceProxyPushSupplier	-  This module implements the OMG  CosNotifyChannelAdmin::SequenceProxyPushSupplier inter-
       face.

DESCRIPTION

       To get access to the record definitions for the structures use:
       -include_lib("cosNotification/include/*.hrl").

       This module also exports the functions described in:

	 * CosNotifyComm_NotifySubscribe

	 * CosNotification_QoSAdmin

	 * CosNotifyFilter_FilterAdmin

	 * CosNotifyChannelAdmin_ProxySupplier

EXPORTS

       connect_sequence_push_consumer(SequenceProxyPushSupplier, PushConsumer) -> Reply

	      Types  SequenceProxyPushSupplier = #objref
		     PushConsumer = #objref
		     Reply = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}} | {'EXCEPTION', #'CosEventChannelAdmin_TypeError'{}}

	      This operation connects a PushConsumer to the target object. If a connection already exists or the  function  psuh_structured_events
	      is not supported the exceptions AlreadyConnected or TypeError will be raised respectively.

       suspend_connection(SequenceProxyPushSupplier) -> Reply

	      Types  SequenceProxyPushSupplier = #objref
		     Reply = ok | {'EXCEPTION', #'CosNotifyChannelAdmin_ConnectionAlreadyInactive'{}} | {'EXCEPTION', #'CosNotifyChannelAdmin_Not-
		     Connected'{}}

	      This operation suspends the connection between the client and the target object. If  no  connection  exists  or  the  connection	is
	      already suspended an exception is raised.

       resume_connection(SequenceProxyPushSupplier) -> Reply

	      Types  SequenceProxyPullConsumer = #objref
		     Reply = ok | {'EXCEPTION', #'CosNotifyChannelAdmin_ConnectionAlreadyInactive'{}} | {'EXCEPTION', #'CosNotifyChannelAdmin_Not-
		     Connected'{}}

	      If the connection have previously been suspended this operation must used if we want to resume the connection.  If  no  object  have
	      been connected or the connection already is active an exception is raised.

       disconnect_sequence_push_supplier(SequenceProxyPushSupplier) -> ok

	      Types  SequenceProxyPushSupplier = #objref

	      This operation cause the target object to close the connection and terminate.
