object a &raiseError(
[mixed
$code = null], [int
$mode = null], [mixed
$options = null], [string
$userinfo = null])

This method is used to communicate an error and invoke error callbacks etc. Basically a wrapper for PEAR::raiseError without the message string.

Return: PEAR error object
See: PEAR_Error

Parameters:

mixed	`$code`	—	integer error code, or a PEAR error object (all other parameters are ignored if this parameter is an object
int	`$mode`	—	error mode, see PEAR_Error docs
mixed	`$options`	—	If error mode is PEAR_ERROR_TRIGGER, this is the error level (E_USER_NOTICE etc). If error mode is PEAR_ERROR_CALLBACK, this is the callback function, either as a function name, or as an array of an object and method name. For other error modes this parameter is ignored.
string	`$userinfo`	—	Extra debug information. Defaults to the last query and native error code.

array RDQLQuery(
object model
&$model, string
$queryString, [boolean
$returnNodes = true])

Perform an RDQL query on this Model_MDB.

This method returns an associative array of variable bindings. The values of the query variables can either be RAP's objects (instances of Node) if $returnNodes set to TRUE, or their string serialization.

Return: [][?VARNAME] = object Node (if $returnNodes = TRUE) OR array [][?VARNAME] = string
Access: public

Parameters:

string	`$queryString`	—
boolean	`$returnNodes`	—
object model	`&$model`	—

object RDQLResultIterator RDQLQueryAsIterator(
object model
&$model, string
$queryString, [boolean
$returnNodes = true])

Perform an RDQL query on this Model_MDB.

This method returns an RDQLResultIterator of variable bindings. The values of the query variables can either be RAP's objects (instances of Node) if $returnNodes set to TRUE, or their string serialization.

Return: = with values as object Node (if $returnNodes = TRUE) OR object RDQLResultIterator = with values as strings if (if $returnNodes = FALSE)
Access: public

Parameters:

string	`$queryString`	—
boolean	`$returnNodes`	—
object model	`&$model`	—
