abstract class AbstractFileIDHelper implements FileIDHelper (View source)

Traits

A class that can be instantiated or replaced via DI

Constants

EXTENSION_REWRITE_VARIANT

A variant type for encoding a variant filename with a different extension than the original.

protected EXTENSION_ORIGINAL

Use the original file's extension

protected EXTENSION_VARIANT

Use the variant file's extension

Methods

public static 
create(mixed ...$args)

An implementation of the factory method, allows you to create an instance of a class

public static 
singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

public
string
buildFileID(string|ParsedFileID $filename, string $hash = null, string $variant = null, bool $cleanfilename = true)

Map file tuple (hash, name, variant) to a filename to be used by flysystem

protected
string
swapExtension(string $filename, string $variant, int $extIndex)

Get the original file's filename with the extension rewritten to be the same as either the original or the variant extension.

public
string
cleanFilename(string $filename)

Clean up filename to remove constructs that might clash with the underlying path format of this FileIDHelper.

public
bool
lookForVariantRecursive()

Specify if this File ID Helper stores variants in subfolders and require a recursive look up to find all variants.

Details

static Injectable create(mixed ...$args)

An implementation of the factory method, allows you to create an instance of a class

This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();

Parameters

mixed ...$args

Return Value

Injectable

static Injectable singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

string buildFileID(string|ParsedFileID $filename, string $hash = null, string $variant = null, bool $cleanfilename = true)

Map file tuple (hash, name, variant) to a filename to be used by flysystem

Parameters

string|ParsedFileID $filename

Name of file or ParsedFileID object

string $hash

Hash of original file

string $variant

(if given)

bool $cleanfilename

Whether the filename should be cleaned before building the file ID. Defaults to true.

Return Value

string

Adapter specific identifier for this file/version

protected string swapExtension(string $filename, string $variant, int $extIndex)

Get the original file's filename with the extension rewritten to be the same as either the original or the variant extension.

Parameters

string $filename

Original filename without variant

string $variant
int $extIndex

One of AbstractFileIDHelper::EXTENSION_ORIGINAL or AbstractFileIDHelper::EXTENSION_VARIANT

Return Value

string

string cleanFilename(string $filename)

Clean up filename to remove constructs that might clash with the underlying path format of this FileIDHelper.

Parameters

string $filename

Return Value

string

bool lookForVariantRecursive()

Specify if this File ID Helper stores variants in subfolders and require a recursive look up to find all variants.

Return Value
