The inflector target is a string with some placeholders for
variables. Placeholders take the form of an identifier, a colon
(':') by default, followed by a variable name: ':script', ':path',
etc. The filter() method looks for the identifier
followed by the variable name being replaced.
You can change the identifier using the
setTargetReplacementIdentifier() method, or passing it
as the third argument to the constructor:
<?php
// Via constructor:
$inflector = new Zend_Filter_Inflector('#foo/#bar.#sfx', null, '#');
// Via accessor:
$inflector->setTargetReplacementIdentifier('#');
Typically, you will set the target via the constructor. However, you
may want to re-set the target later (for instance, to modify the
default inflector in core components, such as the
ViewRenderer or Zend_Layout).
setTarget() can be used for this purpose:
<?php
$inflector = $layout->getInflector();
$inflector->setTarget('layouts/:script.phtml');
Additionally, you may wish to have a class member for your class
that you can use to keep the inflector target updated -- without
needing to directly update the target each time (thus saving on
method calls). setTargetReference() allows you to do
this:
<?php
class Foo
{
/**
* @var string Inflector target
*/
protected $_target = 'foo/:bar/:baz.:suffix';
/**
* Constructor
* @return void
*/
public function __construct()
{
$this->_inflector = new Zend_Filter_Inflector();
$this->_inflector->setTargetReference($this->_target);
}
/**
* Set target; updates target in inflector
*
* @param string $target
* @return Foo
*/
public function setTarget($target)
{
$this->_target = $target;
return $this;
}
}
