addDependencyToFrameworkToAllExtensions()

TYPO3\CMS\Core\Package\DependencyResolver::addDependencyToFrameworkToAllExtensions ( array  $packageStateConfiguration, array  $rootPackageKeys  )

protected

Adds all root packages of current dependency graph as dependency to all extensions

This ensures that the framework extensions (aka sysext) are always loaded first, before any other external extension.

Parameters

array	$packageStateConfiguration
array	$rootPackageKeys

Returns

array

buildDependencyGraph()

TYPO3\CMS\Core\Package\DependencyResolver::buildDependencyGraph ( array  $packageStateConfiguration )

protected

Builds the dependency graph for all packages

This method also introduces dependencies among the dependencies to ensure the loading order is exactly as specified in the list.

Parameters

array

$packageStateConfiguration

Returns

array

convertConfigurationForGraph()

TYPO3\CMS\Core\Package\DependencyResolver::convertConfigurationForGraph ( array  $packageStatesConfiguration, array  $packageKeys  )

protected

Convert the package configuration into a dependency definition

This converts "dependencies" and "suggestions" to "after" syntax for the usage in DependencyOrderingService

array	$packageKeys

Returns
