Syntax

   @Count([REJECTABLE][,<domain>[,<startVal>[,<modulo>]]][,NO_LOG])   

Arguments

   REJECTABLE

      Rejects features if this keyword is specified.

      Range: N/A

   <domain> 
   
      A counter name. Each time @Count is invoked, it returns and increments the 
      count associated with the domain name. This allows many different counters 
      to be used during a single translation. If this parameter is not 
      specified, the default domain is assumed.

      Range: Any String 
        
   <startVal>  
   
      The starting value of the counter. The counter is incremented from the 
      start value.

      Range: Any Integer   
      
   <modulo> 
   
      The modulo value of the counter. The counter returns a value between zero and <modulo> - 1. 

      Range: Any Integer   
      
   NO_LOG      
   
      Prevents FME from logging this domain.

      Range: N/A
   
Configuration

   The @Count function accepts the following configuration line:

   Count MAX_TO_LOG <number>

   If this configuration line is not present, a maximum of 50 count domains will 
   be logged by default.

   <number> 
   
      Integer >= -1  
      
      Sets the maximum number of count domains that will be logged. If -1 is 
      specified, all count domains are logged.

Description

   This function provides a mechanism for generating unique numbers and 
   assigning them to feature attributes during a translation. Because it outputs 
   the final counts in each of the domains to the log file, it can also be used 
   as a feature function to count features that matched the correlation lines. 
   In this case, the log file records the total number of times the function was 
   invoked, even though its result was not stored in any attribute. 

   The optional domain parameter is used to have several different counters 
   active during a single translation. For example, unique line numbers starting 
   at 0 can be assigned to all lines by invoking @Count(lineCounter). During the 
   same run, unique polygon numbers starting at 0 can be assigned to all 
   polygons by using @Count(polygonCounter).

   If no domain name is specified, then the default domain will be assumed.

   The optional startVal parameter specifies a starting value for the counter. 
   This is useful for applications where ranges of values have meanings in the 
   problem domain. 

   The optional modulo parameter enables a counter to be created that cycles 
   from 0 to modulo - 1. This is useful when using counters as lookup values 
   with the @Lookup function.

   The NO_LOG flag may be specified to prevent the FME from logging this domain.
   
TO BE RESOLVED

   It appears as though there are a couple of other undocumented specifications 
   for @Count:
   
      @Count(fme_attribute_name,<attrName>[,<startVal>[,<modulo>]][,NO_LOG])
      @Count(fme_encoded,<encodedDomain>[,<startVal>[,<modulo>]][,NO_LOG])
