FileExistenceResource
class FileExistenceResource implements SelfCheckingResourceInterface, Serializable
FileExistenceResource represents a resource stored on the filesystem.
Freshness is only evaluated against resource creation or deletion.
The resource can be a file or a directory.
Methods
| __construct(string $resource) | ||
| string | __toString() Returns a string representation of the Resource. | |
| string | getResource() | |
| bool | isFresh(int $timestamp) Returns true if the resource has not been updated since the given timestamp. | |
| serialize() {@inheritdoc} | ||
| unserialize($serialized) {@inheritdoc} |
Details
__construct(string $resource)
Parameters
| string | $resource | The file path to the resource |
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 file path to the resource |
bool isFresh(int $timestamp)
Returns true if the resource has not been updated since the given timestamp.
Parameters
| int | $timestamp | The last time the resource was loaded |
Return Value
| bool | True if the resource has not been updated, false otherwise |
serialize()
{@inheritdoc}
unserialize($serialized)
{@inheritdoc}
Parameters
| $serialized |
