$_cacheTimeout  : int
cache timeout (seconds).
$_cancelCache  : bool
When the cache system is activated, says if the cache should be generated or not you set it to false in _createContent or _prepareTpl, in specific case.
$_params  : array<string|int, mixed>
list of zone parameters.
$_tpl  : jTpl
the jtpl object created automatically by jZone if you set up _tplname you can use it in _prepareTpl.
$_tplname  : string
template selector If you want to use a template for your zone, set its name in this property in your zone, and override _prepareTpl. Else, keep it to empty string, and override _createContent.
$_tplOutputType  : string
says the type of the output of the template, in the case of the result of the zone is not used in a response in the same output type.
$_useCache  : bool
If we're using cache on this zone You should override it in your class if you want activate the cache.
__construct()  : mixed
constructor.

_createContent()  : string
create the content of the zone by default, it uses a template, and so prepare a jTpl object to use in _prepareTpl.
_execMetaFunc()  : mixed
_generateContentAndCatchMetaCalls()  : array<string|int, mixed>
When the zone generated content is in cache, the template content is not executed, so zones called in the template (via the `{zone}` plugin) are not called. In this case, meta plugin of their templates are not processed.

override this method if you want do additionnal thing on the template object Example : do access to a dao object.. Note : the template object is in the _tpl property.

Properties

$_cacheTimeout

cache timeout (seconds).

protected int $_cacheTimeout = 0

set to 0 if you want to delete cache manually.

$_cancelCache

When the cache system is activated, says if the cache should be generated or not you set it to false in _createContent or _prepareTpl, in specific case.

protected bool $_cancelCache = alse

$_params

list of zone parameters.

protected array<string|int, mixed> $_params

$_tpl

the jtpl object created automatically by jZone if you set up _tplname you can use it in _prepareTpl.

protected jTpl $_tpl

$_tplname

template selector If you want to use a template for your zone, set its name in this property in your zone, and override _prepareTpl. Else, keep it to empty string, and override _createContent.

protected string $_tplname = 'check_install'

$_tplOutputType

says the type of the output of the template, in the case of the result of the zone is not used in a response in the same output type.

protected string $_tplOutputType = ''

For example, the output type of a ajax response is text, but the template can contains html, so the template should be treated as html content, so you should put 'html' here. If empty, the output type will be the output type of the current response.

If we're using cache on this zone You should override it in your class if you want activate the cache.

Parameters
$params : mixed = array()
Return values

public static clearAll([string $name = '' ]) : mixed
Parameters
$name : string = ''

zone selector

Return values
mixed

clearCache()

Delete the cache of the current zone.

public clearCache() : mixed
Return values
mixed

get()

get the content of a zone.

public static get(string $name[, array<string|int, mixed> $params = array() ]) : string
Parameters
$name : string

zone selector

$params : array<string|int, mixed> = array()

parameters for the zone

Tags
since
1.0b1
Return values
string

the generated content of the zone

getContent()

get the zone content Return the cache content if it is activated and if it's exists, or call _createContent.

public getContent() : string
Return values
string

zone content

param()

gets the value of a parameter, if defined. Returns the default value instead.

public param(string $paramName[, mixed $defaultValue = null ]) : mixed
Parameters
$paramName : string

the parameter name

$defaultValue : mixed = null

the parameter default value

Return values
mixed

the param value

_createContent()

create the content of the zone by default, it uses a template, and so prepare a jTpl object to use in _prepareTpl.

protected _createContent() : string

zone parameters are automatically assigned in the template If you don't want a template, override it in your class.

Return values
string

generated content

_execMetaFunc()

protected _execMetaFunc(mixed $resp, mixed $_file) : mixed
Parameters
$resp : mixed
$_file : mixed
Return values
mixed

_generateContentAndCatchMetaCalls()

When the zone generated content is in cache, the template content is not executed, so zones called in the template (via the `{zone}` plugin) are not called. In this case, meta plugin of their templates are not processed.

protected _generateContentAndCatchMetaCalls() : array<string|int, mixed>

In order to process meta of children zone, we catch all calls of methods of the global response object (did by the meta plugins), to generate a function that will do same calls when getting the cache content of the zone.

FIXME: see if a better solution could be the creating of a jZone::meta() that will do a jTpl::meta() of its template, and jZone::meta() would be added into the meta content function of the generated template by the '{zone}' plugin.

Return values
array<string|int, mixed>

_prepareTpl()

override this method if you want do additionnal thing on the template object Example : do access to a dao object.. Note : the template object is in the _tpl property.

protected _prepareTpl() : mixed
Return values
mixed

getCacheId()

It should returns a list of values that are used for the cache Id.

protected getCacheId() : array<string|int, mixed>

By default, it returns all zone parameters. But some parameters may have values (like some object properties) that are not used for the zone and unfortunately which changed often. The Cache id is then not 'stable' and the cache system may generate a cache at each call.

So you can redefine this method to return only values that should be used as cache ID (I.e. which determines the uniqueness of the zone content)

Return values
array<string|int, mixed>

list of values that are used for the cache Id

_callZone()

instancy a zone object, and call one of its methods.

private static _callZone(string $name, string $method, array<string|int, mixed> &$params) : mixed
Parameters
$name : string

zone selector

$method : string

method name

$params : array<string|int, mixed>

arguments for the method

Return values
mixed

the result returned by the method

_getCacheFiles()

Get the list of cache filenames.

private _getCacheFiles([mixed $forCurrentResponse = true ]) : array<string|int, mixed>
Parameters
$forCurrentResponse : mixed = true
Return values
array<string|int, mixed>

list of filenames
