Properties

Methods

__construct()

public __construct(string $resource[, bool|null $exists = null ]) : mixed
Parameters
$resource : string

The fully-qualified class name

$exists : bool|null = null

Boolean when the existency check has already been done

__toString()

Returns a string representation of the Resource.

public __toString() : string

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 values
string

isFresh()

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

public isFresh(int $timestamp) : bool
Parameters
$timestamp : int

The last time the resource was loaded
