Base is the base Business::Payroll class.
NOTE: bool = 1(true), 0(false)
Creates a new instance of the Business::Payroll::Base object.
returns: object reference
Variables:
error - bool errorString - scalar _errors_ - hash contains the following error hashes: missing, invalid, valid, unknown, extraInfo - holds extra info about an entry in the missing or invalid hashes. errorPhrase - "() - Error!<br>\n" missingArgument - "%s is missing" invalidArgument - "%s = '%s' is invalid"
Returns 1 or 0 to indicate if the object is valid. The error will be available via errorMessage().
This method will set the error condition if an argument is specified. The current error state is returned, regardless of if we are setting an error or not. A \n is appended to the errorString so you don't have to provide it. errorString is prefixed with the caller's full method name followed by the errorPhrase string. You can either specify the errorString value by name: $self->error(errorString => "This is an error!"); or by value: $self->error("This is an error!"); If you specify multiple arguments (in pass by value mode), then we check to see if the first argument contains %'s that are not \ escaped and are not %%. If this is the case, then the incoming arguments will be passed through sprintf() for formatting, else we just join them with a space ' ' and append them to the current errorString. To see if an error happened: if ($self->error) { die "Error: " . $self->errorMessage; }
DEPRECATED: see error() optional: errorString returns: nothing Sets error = 1 and errorString = string passed in. The errorString is prefixed with the caller's full method name followed by the errorPhrase string. You can either call as setError(errorString => $string) or setError($string) If you do not specify anything, we blow an error telling you to specify errorString. \n is appended to the contents of the errorString passed in.
optional: errorString returns: nothing Sets error = 1 and prefixes errorString with string passed in. The errorString is prefixed with the caller's full method name followed by the errorPhrase string. You can either specify the errorString value by name: $self->prefixError(errorString => "This is an error!"); or by value: $self->prefixError("This is an error!"); If you specify multiple arguments (in pass by value mode), then we check to see if the first argument contains %'s that are not \ escaped and are not %%. If this is the case, then the incoming arguments will be passed through sprintf() for formatting, else we just join them with a space ' ' and append them to the current errorString. If you don't specify anything then If you have a previous error, we prefix the caller info to that error message.
DEPRECATED: see error() optional: errorString returns: nothing Sets error = 1 and postfixes errorString with string passed in. The errorString is prefixed with the caller's full method name followed by the errorPhrase string. You can either call as postfixError(errorString => $string) or postfixError($string) If you don't specify anything then we call setError and inform you that you need to specify the errorString value.
DEPRECATED: see error() Returns the value of error.
Returns the value of errorString.
Returns the value of errorString. Alternative to errorMessage().
Resets the error condition flag and string.
Adds an entry for name to the missing hash. If you specify another value, it will be stored as extra info about why this is missing. Ex: $self->missing("personObj"); would signal that personObj was not found. $self->missing("personObj", "this is a test."); would signal that personObj was not found and that you wanted to tell the user that "this is a test.".
Adds an entry for name with it's value to the valid hash. Ex: $self->valid("name", "John Doe"); would signal that name was found and specify the value we got.
Adds an entry for name with it's value in the invalid hash so you know it was invalid and what the user specified. If extraInfo is specified, then it is tacked on after the value part is displayed so you can inform the user of extra conditions about why this was invalid. Ex: $self->invalid("name", ""); would signal that name was found but it was invalid and the value the user sent us. $self->invalid("name", "1", "names can not start with digits."); would signal that name = '1' was invalid and then let you give the user more feedback as to why "names can not start with digits."
Adds an entry for name with it's value in the unknown hash so you know it was specified but the calling program didn't know how to handle it. Ex: $self->unknown("123num", "xdy391234ksldfj.askj28095;");
Returns the hash of name entries that were required but not found or the array of name entries if in list context.
Returns the hash of name, value pairs that were found to be invalid or the array of name entries if in list context.
Returns the hash of name, value pairs that were found to be valid or the array of name entries if in list context.
Returns the hash of name, value pairs that were found to be unknown or the array of name entries if in list context.
Returns the value from the missing hash associated with entry.
Returns the value from the invalid hash associated with entry.
Returns the value from the valid hash associated with entry.
Returns the value from the unknown hash associated with entry.
HTTP Form encodes the string to protect against xss (cross site scripting) or for embedding in an HTML Form.
Generates the Error String for the specified type. type = missing, invalid, all When type = all, then we generate first the missing then the invalid error strings. type = missing uses the missingArgument language phrase. type = invalid uses the invalidArgument language phrase. Ex: $self->setError($self->genErrorString("missing"));
Returns 1 if name is found in the missing hash, else 0.
Returns 1 if name is found in the invalid hash, else 0.
Returns 1 if name is found in the valid hash, else 0.
Returns 1 if name is found in the unknown hash, else 0.
Empties the specified error hash. type can be all, missing, invalid, valid, unknown When type = all, then we clear all the hashes, otherwise we just clear the specified hash. Ex: $self->clearErrors("missing"); would clear just the missing entries.
Returns the number of entries that were required but not found.
Returns the number of entries that were found to be invalid.
Returns the number of entries that were found to be valid.
Returns the number of entries that were found to be unknown.
Takes a string of comma seperated arguments that are taken from the current object and inserted into a hash. Returns the hash of arguments capable of being passed to a new method. Ex: my %args = $self->extract("error, errorString"); Would return a hash containing the error and errorString variables from the current object.
All data fields are accessible by specifying the object and pointing to the data member to be modified on the left-hand side of the assignment. Ex. $obj->variable($newValue); or $value = $obj->variable;
