Result Class
Jump to: navigation, search

An instance of the Result class is returned by many of the Java APIs.

Contents

Considerations
  • If the return code is less than zero, it is an error code.
The Result object contains an error message that explains the error.
  • If the return code is zero, the call succeeded, but no records are present.
This value is returned by an add, update, or delete, or when no records match specified search criteria.
  • If the return code is greater than zero, the value is the number of records in the result set.
In that case, there are two options:
  • If the API expected to return a single record, as in a getRecord operation, the getParameters method (below) returns a Parameters object that contains the record fields.
  • If the API expected to return multiple records, as in an execSQL query or a searchRecords operation, then the getIterator method (below) is used to cycle through the list of Parameters objects contained in the Result set (one per record). (In that case, the getParameters method returns null.)

Methods

The Result class has following methods.

getCode

Gets the error code for record handling calls such as addRecord, updateRecord, deleteRecord, and so on.

For the searchRecords and getRecord calls, the code indicates the number of records returned.

These are the rules that the record handling calls follow for setting the error code:

  • All record handling calls set the error code to negative one (-1) if not successful.
  • Most record handling calls set the error code to zero (0) if successful. The exceptions to this rule are:
    • getRecord sets the error code to one (1) if successful
    • searchRecord sets the error code to the number of records retrieved if successful

Signature of the Method

int getCode()
Example
This example calls addRecord, assigning the returned value to an instance of Result and calling Result.getCode to assign the error code to a variable which is then conditionally checked to determine the code to execute.
Parameters myAccount = Functions.getParametersInstance();
myAccount.add("name", "Acme Solutions");
Result result = Functions.addRecord("ACCOUNT", params);
int returnCode = result.getCode();
if(returnCode < 0)
{
    String msg = "Account could not be added";
    Functions.debug(msg + ":\n" + result.getMessage());  // Log details
    Functions.throwError(msg + ".");                     // Error dialog
}
else
{
  // take other actions according to
  // your business logic.
}

getID

Gets the record identifier set by addRecord and generateDocument. When these calls fail, the record identifier is an empty string.

Signature of the Method

String getID()
Example
This example calls addRecord, assigning the returned value to an instance of Result and calling Result.getCode to assign the error code to a variable which is then conditionally checked to determine the code to execute. If the call was successful, the code calls getID to extract the record identifier.
Parameters myAccount = Functions.getParametersInstance();
myAccount.add("name", "Acme Solutions");
Result result = Functions.addRecord("ACCOUNT", myAccount);
int returnCode = result.getCode();
if(returnCode < 0)
{
    String msg = "Account could not be added";
    Functions.debug(msg + ":\n" + result.getMessage());  // Log details
    Functions.throwError(msg + ".");                     // Error dialog
}
else
{
  String id = result.getID();
  // use the ID to addTask, addActivity or
  // add any other related object.
}

getMessage

Gets the message that indicates success or failure.

Signature of the Method

String getMessage()
Example
This example calls addRecord, assigning the returned value to an instance of Result and calling Result.getCode to assign the error code to a variable which is then conditionally checked to determine the code to execute. If the call was not successful, the code calls getMessage to extract the message string.
Parameters myAccount = Functions.getParametersInstance();
myAccount.add("name", "Acme Solutions");
Result result = Functions.addRecord("ACCOUNT", params);
int returnCode = result.getCode();
if(returnCode < 0)
{
    String msg = "Error adding Acme Solutions account";
    Functions.debug(msg + ":\n" + result.getMessage());  // Log details
    Functions.throwError(msg + ".");                     // Error dialog
}
else
{
  String id = result.getID();
  // use the ID to addTask, addActivity or
  // add any other related object.
}

getIterator

Gets a ParametersIterator object after a searchRecords call.

Signature of the Method

ParametersIterator getIterator()
Example
This example calls searchRecords, assigning the returned value to an instance of Result and calling Result.getCode to assign the error code to a variable which is then conditionally checked to determine the code to execute. If the call was successful and records were returned, the code creates an instance of ParametersIterator. In a while loop, the code calls the ParametersIterator.next method to get an instance of Parameters from which it then extracts the record identifier.
Result result = Functions.searchRecords("ACCOUNT", "record_id,name, number,city", "name starts with 'Acme'");
int returnCode = result.getCode();
if(returnCode < 0)
{
    String msg = "Error searching Account records";
    Functions.debug(msg + ":\n" + result.getMessage());  // Log details
    Functions.throwError(msg + ".");                     // Error dialog
}
else if(returnCode == 0)
{
  Functions.throwError("No records found");
}
else
{
  ParametersIterator iterator = result.getIterator();
  while(iterator.hasNext())
  {
    Parameters myAccount = iterator.next();
    String id = myAccount.get("record_id");
    // execute your other business logic
  }
}

getParameters

Creates a Parameters object.

Signature of the Method

Parameters getParameters()
Example
This example calls getRecord, assigning the returned value to an instance of Result and calling Result.getCode to assign the error code to a variable which is then conditionally checked to determine the code to execute. If the call was successful and records were returned, the code creates an instance of Parameters and extracts the name.
String accountID = "";
// Some code to populate accountID variable
Result result = Functions.getRecord("ACCOUNT", accountID);
int returnCode = result.getCode();
if(returnCode < 0)
{
    String msg = "Error retrieving Account record";
    Functions.debug(msg + ":\n" + result.getMessage());  // Log details
    Functions.throwError(msg + ".");                     // Error dialog
}
else
{
  Parameters params = result.getParameters();
  String accountName = params.get("name");
  // execute your other business logic based on name
}
