Details

__construct(string $resource, bool $exists = null)

Parameters

string $resource The fully-qualified class name
bool $exists Boolean when the existency check has already been done

at line 44
string __toString()

Returns a string representation of the Resource.

This method is necessary to allow for resource de-duplication, for example by means of array_unique(). The string returned need not have a particular meaning, but has to be identical for different ResourceInterface instances referring to the same resource; and it should be unlikely to collide with that of other, unrelated resource instances.

Return Value

string A string representation unique to the underlying Resource

at line 52
string getResource()

Return Value

string The file path to the resource

at line 62
bool isFresh(int $timestamp)

Returns true if the resource has not been updated since the given timestamp.

Parameters

int $timestamp The last time the resource was loaded

Return Value

bool True if the resource has not been updated, false otherwise
