	{
		foreach ($this->parents as $parent)
		{
			if ($comment = $parent->getDocComment())
			{
				// Found a description for this class

	// incomplete documentation
	foreach ($this->parents as $parent)
	{
		if ($parent->name == 'Kodoc_Missing')
		{
			$result .= "[!!] **This class, or a class parent, could not be
			           found or loaded. This could be caused by a missing
			           module or other dependancy. The documentation for
			           class may not be complete!**";

public static class_methods( ) (defined in Kohana_Kodoc)

Get all classes and methods of files in a list.

I personally don't like this as it was used on the index page. Way too much stuff on one page. It has potential for a package index page though. For example: class_methods( Kohana::list_files('classes/sprig') ) could make a nice index page for the sprig package in the api browser ~bluehawk

Source Code

public static function class_methods(array $list = NULL)
{
	$list = Kodoc::classes($list);

	$classes = array();

	foreach ($list as $class)
	{
		// Skip transparent extension classes
		if (Kodoc::is_transparent($class))
			continue;

		$_class = new ReflectionClass($class);

		$methods = array();

		foreach ($_class->getMethods() as $_method)
		{
			$declares = $_method->getDeclaringClass()->name;

			// Remove the transparent prefix from declaring classes
			if ($child = Kodoc::is_transparent($declares))
			{
				$declares = $child;
			}

			if ($declares === $_class->name OR $declares === "Core")
			{
				$methods[] = $_method->name;
			}
		}

		sort($methods);

		$classes[$_class->name] = $methods;
	}

	return $classes;
}

public static classes( [ array $list = NULL ] ) (defined in Kohana_Kodoc)

	$ext_length = strlen(EXT);

	foreach ($list as $name => $path)
	{

public static is_transparent( string $class [, array $classes = NULL ] ) (defined in Kohana_Kodoc)

Checks whether a class is a transparent extension class or not.

This method takes an optional $classes parameter, a list of all defined class names. If provided, the method will return false unless the extension class exists. If not, the method will only check known transparent class prefixes.

Transparent prefixes are defined in the userguide.php config file:

'transparent_prefixes' => array(
    'Kohana' => TRUE,
);

Module developers can therefore add their own transparent extension namespaces and exclude them from the userguide.

Parameters

  • string $class required - The name of the class to check for transparency
  • array $classes = NULL - An optional list of all defined classes

Tags

Return Values

  • false - If this is not a transparent extension class
  • string - The name of the class that extends this (in the case provided)

Source Code

public static function is_transparent($class, $classes = NULL)
{

	static $transparent_prefixes = NULL;

	if ( ! $transparent_prefixes)
	{
		$transparent_prefixes = Kohana::$config->load('userguide.transparent_prefixes');
	}

	// Split the class name at the first underscore
	$segments = explode('_',$class,2);

	if ((count($segments) == 2) AND (isset($transparent_prefixes[$segments[0]])))
	{
		if ($segments[1] === 'Core')
		{
			// Cater for Module extends Module_Core naming
			$child_class = $segments[0];
		}
		else
		{
			// Cater for Foo extends Module_Foo naming
			$child_class = $segments[1];
		}
		
		// It is only a transparent class if the unprefixed class also exists
		if ($classes AND ! isset($classes[$child_class]))
			return FALSE;
		
		// Return the name of the child class
		return $child_class;
	}
	else
	{
		// Not a transparent class
		return FALSE;
	}
}

Make a class#member API link using an array of matches from Kodoc::$regex_class_member

Parameters

  • array $matches required - Array( 1 => link text, 2 => class name, [3 => member name] )

Source Code

public static function link_class_member($matches)
{
	$link = $matches[1];
	$class = $matches[2];
	$member = NULL;

	if (isset($matches[3]))

		// If the first char is a $ it is a property, e.g. Kohana::$base_url
		if ($matches[3][0] === '$')
		{
			$member = '#property:'.substr($matches[3], 1);
		}
		else
		{
			$member = '#'.$matches[3];
		}
	}

	return HTML::anchor(Route::get('docs/api')->uri(array('class' => $class)).$member, $link, NULL, NULL, TRUE);
