Methods

checkDependencies()  : mixed
Checks dependencies for special cases (currently typo3 and php)

injectManagementService()  : mixed
setSkipDependencyCheck()  : mixed
checkExtensionDependency()  : bool
Main controlling function for checking dependencies Dependency check is done in the following way: - installed extension in matching version ? - return true - available extension in matching version ? - mark for installation - remote (TER) extension in matching version? - mark for download
checkPhpDependency()  : bool
Returns true if current php version fulfills extension requirements
checkTypo3Dependency()  : bool
Returns true if current TYPO3 version fulfills extension requirements
downloadExtensionFromRemote()  : mixed
Handles checks to find a compatible extension version from TER to fulfill given dependency
getCompatibleExtension()  : Extension|null
Get the latest compatible version of an extension that's compatible with the current core and PHP version.
getLatestCompatibleExtensionByDependency()  : Extension|null
Get the latest compatible version of an extension that fulfills the given dependency from TER
isAvailableVersionCompatible()  : bool
Checks whether the available version is compatible
isDependentExtensionAvailable()  : bool
Checks whether the needed extension is available (not necessarily installed, but present in system)
isDependentExtensionLoaded()  : bool
isDownloadableVersionCompatible()  : bool
Checks whether a compatible version of the extension exists in TER
isExtensionDownloadableFromRemote()  : bool
Checks whether a ter extension with $extensionKey exists
isLoadedVersionCompatible()  : bool
setAvailableExtensions()  : mixed
Setter for available extensions gets available extensions from list utility if not already done
