Disk Forwarding MultiForwardingUDR Input - Batch

When the agent is set to use MultiForwardingUDR input, it accepts input of the UDR type MultiForwardingUDR declared in the package FNT. The declaration follows:

internal MultiForwardingUDR
{ // Entire file content 
 byte[] content; // Target filename and directory 
 FNTUDR fntSpecification; 
};

The content of the MultiForwardingUDR will be stored at the path that you have set in the fntSpecification field. Use the APL functions fntAddString and fntAddDirDelimiter to set the value of this field. For further information about these functions, see FNTUDR Functions in APL Reference Guide.

When the files are received they are written to temp files in the DR_TMP_DIR directory situated in the root output folder. The files are moved to their final destination when an end batch message is received. A runtime error will occur if any of the fields have a null value or if the path is invalid on the target file system.

A UDR of the type MultiForwardingUDR which has a target filename that is not identical to its precedent is saved in a new output file.

Note!

MultiforwardingUDR’s with their own specific target filenames will be saved into their specific output files. UDRs with filename A will be saved to filename A and UDRs with filename B will be saved to filename B regardless of precedence.

Non-existing directories will be created if the Create Non-Existing Directories check box under the Filename Template tab is checked. If not checked, a runtime error will occur if a previously unknown directory exists in the FNTUDR of an incoming MultiForwardingUDR. Every configuration option referring to bytearray input is ignored when MultiForwardingUDRs are expected.

Example - APL code to send MultiForwardingUDRs

This example shows the APL code used in an Analysis agent connected to a forwarding agent expecting input of type MultiForwardingUDRs.

import ultra.FNT;

MultiForwardingUDR createMultiForwardingUDR
(string dir, string file, bytearray fileContent){

    //Create the FNTUDR
    FNTUDR fntudr = udrCreate(FNTUDR);
    fntAddString(fntudr, dir);
    fntAddDirDelimiter(fntudr);//Add a directory
    fntAddString(fntudr, file);//Add a file

    MultiForwardingUDR multiForwardingUDR =
    udrCreate(MultiForwardingUDR);
    multiForwardingUDR.fntSpecification = fntudr;
    multiForwardingUDR.content = fileContent;

    return multiForwardingUDR;
}

consume {

    bytearray file1Content;
    strToBA (file1Content, "file nr 1 content");

    bytearray file2Content;
    strToBA (file2Content, "file nr 2 content");

    //Send MultiForwardingUDRs to the forwarding agent
    udrRoute(createMultiForwardingUDR
    ("dir1", "file1", file1Content));
    udrRoute(createMultiForwardingUDR
    ("dir2", "file2", file2Content));
}

The Analysis agent mentioned previous in the example will send two MultiForwardingUDRs to the forwarding agent. Two files with different contents will be placed in two separate sub folders in the root directory. The Create Non-Existing Directories check box under the Filename Template tab in the configuration of the forwarding agent must be checked if the directories do not previously exist.
