Constructor & Destructor Documentation

◆ __construct()

xmldb_object::__construct ( $name)

Creates one new xmldb_object.

Parameters
string$name

Reimplemented in xmldb_file, xmldb_structure, and xmldb_table.

Member Function Documentation

◆ checkName()

xmldb_object::checkName ( )

This function will check if one key name is ok or no (true/false) only lowercase a-z, 0-9 and _ are allowed.

Return values
bool

◆ checkNameValues()

xmldb_object::checkNameValues ( $arr)

This function will check that all the elements in one array have a correct name [a-z0-9_].

Parameters
array$arr
Return values
bool

◆ comma2array()

xmldb_object::comma2array ( $string)

Returns one array of elements from one comma separated string, supporting quoted strings containing commas and concat function calls.

Parameters
string$string
Return values
array

◆ debug()

xmldb_object::debug ( $message)

This function will perform the central debug of all the XMLDB classes being called automatically every time one error is found.

Apart from the main actions performed in it (XMLDB agnostic) it looks for one function called xmldb_debug() and invokes it, passing both the message code and the whole object. So, to perform custom debugging just add such function to your libs.

Call to the external hook function can be disabled by request by defining XMLDB_SKIP_DEBUG_HOOK

Parameters
string$message

◆ findObjectInArray()

xmldb_object::findObjectInArray ( $objectname,
$arr )

Returns the position of one object in the array.

Parameters
string$objectname
array$arr
Return values
mixed

◆ fixPrevNext()

xmldb_object::fixPrevNext ( & $arr)

Reconstruct previous/next attributes.

Parameters

This function will set the next of the xmldb_object.

Parameters
string$next

◆ setPrevious()

xmldb_object::setPrevious ( $previous)

This function will set the previous of the xmldb_object.

Parameters
string$previous

◆ validateDefinition()

xmldb_object::validateDefinition ( xmldb_table $xmldb_table = null)

Validates the definition of objects and returns error message.

The error message should not be localised because it is intended for developers, end users and admins should never see these problems!
