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)

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
