Hi ,

I am trying to parse field values using the below code in Groovy evaluator for field field1 :

for (record in records) {
  try {     
    StringBuilder ret = new StringBuilder(record.value['field1'].length());
    for (String word : record.value['field1'].split(" ")) {
            if (!word.isEmpty()) {
                ret.append(word.substring(0, 1).toUpperCase())
                ret.append(word.substring(1).toLowerCase())}
            if (!(ret.length()==record.value['field1'].length()))
                ret.append(" ")
        }

    record.value['field1'] = ret.toString()

    output.write(record)
  } catch (e) {
    log.error(e.toString(), e)
    error.write(record, e.toString())
  }
}

I want to apply the same code to multiple fields from the incoming data.

Can you please suggest on how to define a method in Groovy evaluator so that we can pass the incoming required fields to the method ??

@metadaddy any suggestions on how to define a method in Groovy evaluator which can be used for required fields

Hi!

Replace your code with the following and it should work:

def upperCaseFirstLetter(fieldValue)    {
  StringBuilder ret = new StringBuilder(fieldValue.length());
  for (String word : fieldValue.split(" ")) {
    if (!word.isEmpty()) {
        ret.append(word.substring(0, 1).toUpperCase())
        ret.append(word.substring(1).toLowerCase())}
    if (!(ret.length()==fieldValue.length()))
        ret.append(" ")
  }
  return ret.toString()
}

for (record in records) {
  try {     

    //Uncomment to process ALL fields
    //for ( item in record.value ) {
    //  record.value[item.key] = upperCaseFirstLetter(record.value[item.key])
    //}

    //Process individual fields
    record.value['field1'] = upperCaseFirstLetter(record.value['field1'])
    record.value['field2'] = upperCaseFirstLetter(record.value['field2'])    

    output.write(record)
  } catch (e) {
    log.error(e.toString(), e)
    error.write(record, e.toString())
  }
}

Cheers, Dash

Hi Dash, I need to apply the function to all fields from source (suppose there are 100 fields from source). Instead of defining this method to each field, how can I define to all the fields ?

Look at the code I've already provided where it says "Uncomment to process ALL fields"
