Parameters

seek

seek( $offset, $whence)

Parameters

stat

stat()

The stat function uses GET requests to the bucket to try and determine if the object is a 'file' or a 'directory', by listing the contents of the bucket and then matching the results against the supplied object name.

If a file ends with "/ then Google Cloud console will show it as a 'folder' in the UI tool, so we consider an object that ends in "/" as a directory as well. For backward compatibility, we also treat files with the "_$folder$" suffix as folders.

tell

tell()

write

write( $data)

Parameters

getMetaData

getMetaData()

Subclass can override this method to return the metadata of the underlying GCS object.

getContentType

getContentType()

Subclass can override this method to return the MIME content type of the underlying GCS object.

createObjectUrl

STATIC   

createObjectUrl( $bucket, $object = null)

Create a URL for a target bucket and optional object.

Parameters

clearStatCache

STATIC   

clearStatCache(string $filename = null)

Clear the stat cache.

Parameters

getReadMemcacheKey

STATIC   

getReadMemcacheKey(string $url, string $range) : string

Create a memcache key for the read data cache. If the filename is long enough that the key would exceed memcache limits, then a hash of the filename and the range is used to generate the key.

We prefer the human readable key format where possible so users can easily identify which files and segments are stored in memcache.

Parameters

Returns

The memcache key to use for storing data.
