function _features_export_maximize_dependencies in Features 7.2

Same name and namespace in other branches

1. 6 features.export.inc \_features_export_maximize_dependencies()
2. 7 features.export.inc \_features_export_maximize_dependencies()

Completes a list of dependencies by adding all indirect dependencies as well.

Mathematically this would be called a 'transitive closure'.

This function is recursive, some of its parameters are only meant to be used in recursive calls.

Parameters

string[] $dependencies: Original list of dependencies. Format: $[*] = $module The array keys will be ignored, which means this has the same result for serial or associative arrays.

string $module_name: (obsolete) Name of the module whose dependencies are being processed. This has no effect whatsoever, so it can be safely omitted.

string[] $maximized: (recursive) List of modules that were already processed in previous recursion levels. Omit in non-recursive call.

bool $first: (recursive) TRUE, if this is not a recursive call.

Return value

string[] Complete list of direct and indirect dependencies. Format: $[] = $module
