interface SelfCheckingResourceInterface implements ResourceInterface
Interface for Resources that can check for freshness autonomously, without special support from external services.
| string | __toString() Returns a string representation of the Resource. | from ResourceInterface |
| bool | isFresh(int $timestamp) Returns true if the resource has not been updated since the given timestamp. |
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.
| string | A string representation unique to the underlying Resource |
Returns true if the resource has not been updated since the given timestamp.
| int | $timestamp | The last time the resource was loaded |
| bool | True if the resource has not been updated, false otherwise |
