UDR Functions

The following functions for UDR described here are:
udrAddError
Adds an error description message to the UDR, which will be visible from the Error Correction System Inspector window or the Data Veracity browser, Error Code column. A UDR can have several error descriptions.
void udrAddError ( drudr myUDR, string ecsErrorCode, string myString )Parameter | Description |
|---|---|
| The UDR to add error message to. |
| An ECS Error Code as defined from the Error Correction System Inspector and Data Veracity browser. |
| Any string to associate with the Error Code. This parameter comprises the Error Case found in the ECS or Data Veracity. Optional. |
Returns | Nothing |
Example - Using udrAddError
The following example appends error text to a UDR, which when displayed in ECS or Data Veracity will look like the following figure:
udrAddError( input, "CALL_ID_ERROR",
"The callId: " +
input.callId +
" Calling number: " +
input.anum );udrClearErrors
Removes all error descriptions, added to a UDR. This is useful when collecting UDRs from ECS or Data Veracity for a new validation which may send them back to ECS or Data Veracity. Adding a new error description, if one already exists, will make it impossible to auto-assign the UDR to a reprocessing group when it arrives to either Data Veracity or the ECS.
void udrClearErrors( drudr myUDR )Parameter | Description |
|---|---|
| The UDR to clear errors from |
Returns | Nothing |
udrClone
Clones a UDR. It is used when having multiple routes leaving the agent, where any of the routes changes the content of a UDR. For complex UDR structures, this can be a heavy operation, and must be used with care.
Parameter | Description |
|---|---|
| The UDR to clone |
Returns | A clone of |
udrContainsError
Returns true if an error description has been added to the UDR.
Parameter | Description |
|---|---|
| The UDR to evaluate for error descriptions |
Returns |
|
udrCreate
Creates a new UDR of the specified type. All fields are included, except for the optional.
Parameter | Description |
|---|---|
| A defined UDR type |
Returns: | A UDR of the specified type |
udrDecode
Decodes a bytearray into a list of UDRs, and returns an error message if the operation fails. To route the UDRs to a subsequent agent, loop through the resulting list routing each element individually.
Note!
Built-in CSV and JSON formats are not supported by udrDecode.
Parameter | Description |
|---|---|
| The name of a defined decoder |
| The list in which the resulting, decoded UDRs will be saved |
| The input data to decode |
| States if Full Decode will be applied. By default, this parameter is set to |
Returns | A string containing nothing ( |
Example - Using udrDecode
A list must be created, not only declared, previously used by udrDecode:
udrEncode
Encodes a UDR.
Parameter | Description |
|---|---|
| The name of a defined encoder |
| The UDR to encode |
Returns | A bytearray |
udrForceDecode
By default, a Decoder only evaluates record sizes and field termination marks. It does not read the field values to evaluate for validity. This is done for each field when it is actually accessed, either from an agent utilizing APL code, or from an Encoder.
The udrForceDecode function will decode each field within a UDR. If a field is not valid, the agent will abort. This function is equal to the Full Decode option in the Decoder window. Note that the function has a negative impact on performance, and must be used mainly for testing purposes.
Parameter | Description |
|---|---|
| The UDR to fully decode |
| An optional argument. If not stated, |
Returns | If decoding succeeds, |
udrGetErrorCodes
Returns a list of strings containing all error codes added to the UDR.
Parameter | Description |
|---|---|
| The UDR |
Returns | A list of strings with all error codes added to the UDR |
udrGetErrorMessages
Returns a list of strings containing all error messages added to the UDR.
 Â
Parameter | Description |
|---|---|
| The UDR |
Returns | A list of strings with all error messages added to the UDR |
udrGetErrorsAsString
Returns a string containing all error information that has been added to the UDR.
Parameter | Descripton |
|---|---|
| The UDR |
Returns | A string with all error information added to the UDR |
udrGetFields
Returns a list of the field names and field information in a UDR.
Parameter | Description |
|---|---|
| The UDR. |
Returns |
A list of the fields in the UDR and the field information. See the information below on |
UDRFieldInfo is the UDR that is populated with the field information of the UDR that contains a list of fields.
The following fields are included in UDRFieldInfo:
Field | Description |
|---|---|
| The name of the field |
| The field type, e g string, int, double etc. |
| This indicates if the field is optional or not. |
| This indicates if the field is read-only or not. |
udrGetValue
Returns the value of fieldName in the myUDR.
Parameter | Description |
|---|---|
| The UDR containing the field of interest |
| A string, exactly matching the name of an existing field. If the field is OPTIONAL and is not present, the function returns Constructed field names, that is subUDR.subField are allowed. If a field in the path is not present, |
Returns | Any, depending on the field type |
udrIsPresent
Returns true if the UDR field is present.
Parameter | Description |
|---|---|
| The full field name including the UDR name. For instance, |
Returns |
If a field is optional and not present, accessing the field will return the default null value that is null for object types, 0 for numeric types and false for boolean types. |
udrMass Functions
The udrMass functions enable you to manage a decoder which purpose is to process large amounts of collected UDRs, while maintaining control over UDRs tailing bytes in between calls to consume .
The udrMass functions include:
udrMassCreateDecoder
udrMassClearBuffer
udrMassDecode
udrMassEOFCheck
udrMassGetDataTail
Â
udrMassCreateDecoder
Creates a decoder object.
Parameter | Description |
|---|---|
| The name of the decoder object. |
Returns: | A decoder object. |
udrMassClearBuffer
The udrMassClearBuffer function clears the remaining buffer in the decoder.
Parameter | Description |
|---|---|
| The decoder object that |
Returns: | Nothing |
udrMassDecode
The udrMassDecode function Decodes the bytearray input data by using the decoder, and generates it as a list.
Parameter | Description |
|---|---|
| The decoder object that |
| The product of the encoding process is saved as a list of UDRs. |
| The input data that is to be encoded into UDRs |
| Use |
Returns: | If decoding fails, an error message is returned. Otherwise, returns |
udrMassEOFCheck
The udrMassEOFCheck function attempts to decode any remaining bytes that are left behind and stored in the decoder. If the function executes and decoding is successful, the procedure sends endBatch to the decoder, the returned string is empty, and the myList parameter contains the UDRs. Otherwise, an error message is generated.
Parameter | Description |
|---|---|
| The decoder object that |
| The data that |
| Use |
Returns: | If decoding fails, an error message is returned. Otherwise, returns |
udrMassGetDataTail
The  udrMassGetDataTail function makes the decoder generate the remaining bytes that it holds. The bytes are still stored in the decoder.
Parameter | Description |
|---|---|
| The decoder object that |
Returns: | The raw bytearray data that the decoder in |
udrRoute
The udrRoute function sends a UDR to a workflow route.
If no call to the route function is made, the agent will not have any outgoing routes in the Workflow Editor environment - it will not be possible to link to a subsequent agent.
The function routes a UDR to all the output routes, or a named output route. If the clone keyword is used, the UDR is cloned before output.
Parameter | Description |
|---|---|
| The UDR to send on |
| The route on which to send the UDR |
| The UDR is cloned before routing on the output/outputs. |
Returns | Nothing |
udrSetValue
Sets the field named fieldName in the UDR myUDR to value .
Parameter | Description |
|---|---|
| The UDR, for which to set the field value |
| A string, exactly matching an existing field. Constructed field names in the form of subUDR.subField are allowed. Trying to set a non-existing field will cause runtime error. |
| A value depending on the field type |
Returns | Nothing |
udrUnsetPresent
In the output files the Encoder maps by default, null fields as present but empty. This can be avoided by clearing a flag, Is Present, using the udrUnsetPresent function.
The field can be changed to Is Present again either via udrSetValue (see the section above, udrSetValue) or regular assignment of fields.
Parameter | Description |
|---|---|
| The full name of the optional field including the UDR name. For instance, |
Returns | Nothing |
