class ClassExistenceResource implements SelfCheckingResourceInterface, Serializable
ClassExistenceResource represents a class existence.
Freshness is only evaluated against resource existence.
The resource must be a fully-qualified class name.
__construct(string $resource, bool $exists = null) | ||
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} |
string | $resource | The fully-qualified class name |
bool | $exists | Boolean when the existency check has already been done |
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 |
string | The file path to the 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 |
