Class: ezcDebugXdebugStacktraceIterator

Iterator class to wrap around debug_backtrace() stack traces. [source]
This iterator class receives a stack trace generated by debug_backtrace() and unifies it as described in the ezcDebugStacktraceIterator interface.

Inherited Member Variables

From ezcDebugStacktraceIterator:
protected  ezcDebugStacktraceIterator::$options

Method Summary

protected array prepare( $stackTrace, $removeElements )
Prepares the stack trace for being stored in the iterator instance.
protected array unifyStackElement( $stackElement )

Returns the number of elements in the iterator.
public mixed ezcDebugStacktraceIterator::current()
Returns the currently selected element of the iterator.
public mixed ezcDebugStacktraceIterator::key()
Returns the key of the currently selected element of the iterator.
public mixed ezcDebugStacktraceIterator::next()
Advances the iterator to the next element.
public bool ezcDebugStacktraceIterator::offsetExists()

Returns if the iterator is on a valid element or at the end.

Methods

prepare

array prepare( array $stackTrace, int $removeElements )
Prepares the stack trace for being stored in the iterator instance.
This method reverses the received $stackTrace, which was created by the Xdebug (http://xdebug.org) debugging extension for PHP, to unify the stacktrace with the one created by ezcDebugPhpStacktraceIterator. Number $removeElements are removed from the top of the $stackTrace.

Parameters

Name Type Description
$stackTrace array  
$removeElements int  

Redefinition of

Method Description
ezcDebugStacktraceIterator::prepare() Prepares the stack trace for being stored in the iterator instance.

unifyStackElement

array unifyStackElement( mixed $stackElement )
Unifies a stack element for being returned to the formatter.
This method ensures that an element of the stack trace conforms to the format expected by a ezcDebugOutputFormatter. The format is defined as follows:
 1.  array(
 2.       'file'      => '<fullpathtofile>',
 3.       'line'      => <lineno>,
 4.       'function'  => '<functionname>',
 5.       'class'     => '<classname>',
 6.       'params'    => array(
 7.           <param_no> => '<paramvalueinfo>',
 8.           <param_no> => '<paramvalueinfo>',
 9.           <param_no> => '<paramvalueinfo>',
10.           ...
11.       )
12.  )

Parameters

Name Type Description
$stackElement mixed

Method Description
ezcDebugStacktraceIterator::unifyStackElement() Unifies a stack element for being returned to the formatter.
