Details
__construct(string $resource)
Constructor.
Parameters
| string | $resource | The file path to the resource | 
Exceptions
| InvalidArgumentException | 
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 | 
string getResource()
Return Value
| string | The canonicalized, absolute path to the resource | 
bool isFresh(int $timestamp)
Returns true if the resource has not been updated since the given timestamp.
Parameters
| int | $timestamp | The last time the resource was loaded | 
Return Value
| bool | True if the resource has not been updated, false otherwise | 
serialize()
unserialize($serialized)
Parameters
| $serialized |
