Methods

__construct()

The class constructor

public __construct([string $resource_id = NULL ]) : mixed
Parameters
$resource_id : string = NULL

The resource ID

Initializes the objects

Return values
mixed

debug()

Output the full dataset without object data (all subobjects are parsed recursively)

public debug() : bool
Return values
bool

true

delete()

Delete identifier with a given id or resource id

public delete(int $id[, bool $is_resource = false ]) : bool
Parameters
$id : int

The id

$is_resource : bool = false

True if the id is a resource id. Otherwise the id is an identifier id.

Return values
bool

Returns true for success and false if no id is given

get()

Returns an array of the full data or (if given) only certain attributes (separated by "|" for a subattribute)

public get([string $attribute = NULL ]) : array<string|int, mixed>|object|string
Parameters
$attribute : string = NULL

The attributes separated by [parent|child]

Return values
array<string|int, mixed>|object|string

The dataset or NULL

get_by_id()

Returns the full dataset or a single attribute

public get_by_id(string $identifier_id) : array<string|int, mixed>
Parameters
$identifier_id : string

The ID of the identifier (should also work with an int param)

Return values
array<string|int, mixed>

The dataset

get_flat_data()

Get the data in a flat format. From subarrays only the first entry is merged

public get_flat_data([bool $hierarchy = false ][, mixed $data = NULL ]) : array<string|int, mixed>
Parameters
$hierarchy : bool = false

Return full flat (standard) or array hierarchy (if true)

$data : mixed = NULL

Use other data than $this->full_data

Return values
array<string|int, mixed>

The flat data

get_flat_data_old()

Get the data in a flat format. From subarrays only the first entry is merged

public get_flat_data_old([bool $hierarchy = false ][, mixed $data = NULL ]) : array<string|int, mixed>
Parameters
$hierarchy : bool = false

Return full flat (standard) or array hierarchy (if true)

$data : mixed = NULL

Use other data than $this->full_data

Return values
array<string|int, mixed>

The flat data

id()

Set a new ID or return the current ID if $id is NULL. The numeric value 0 is also set to NULL.

public id([string $id = NULL ]) : int
Parameters
$id : string = NULL

The current ID

Return values
int

The ID

persist()

Persist the object data to the database

public persist() : bool
Return values
bool

Returns true for success and false for a database error (which can be found in the error object). Returns -1 (int), if the identifier type already exists.

pull_json()

Returns the object data as JSON

public pull_json() : string
Return values
string

The json string

pull_xml()

Returns the object data as XML

public pull_xml([bool $head = false ]) : string
Parameters
$head : bool = false

Return values
string

The xml string

push_xml()

Push an xml into the object (experimental, not finished yet)

public push_xml(string $xml) : bool
Parameters
$xml : string

The xml with the object data

Return values
bool

true (or false on error)

reset()

Reset the whole object (ID = NULL, full_data is empty)

public reset() : bool
Return values
bool

Returns true

set()

Set data in the object

public set(array<string|int, mixed> $data[, bool $writethrough = false ]) : bool
Parameters
$data : array<string|int, mixed>

One or more new key/values for the identifier (data will be merged, same attributes will be overwritten)

$writethrough : bool = false

Write the object to the database immediately

Return values
bool

Returns true for success and false for no data given. Returns -1 (int), if the identifier type already exists.

unset_attribute()

Unsets an attribute

public unset_attribute(string $attribute) : bool
Parameters
$attribute : string

bool

Returns true for success and false for identifier not found

initialize()

Initializes the object by filling the array with data

protected initialize() : bool
Return values
bool

true (or false on error)

array_to_xml()

Convert an array into an xml representation

private array_to_xml(array<string|int, mixed> $data, Pointer &$xml) : bool
Parameters
$data : array<string|int, mixed>

The array with the data

$xml : Pointer

A pointer to the xml

Return values
bool

Parameters
$mixed : mixed = NULL

The variable

Return values
bool

true
