ensureCursor() abstract protected method

abstract protected ensureCursor ( ) : MongoDB\Driver\Cursor
return MongoDB\Driver\Cursor

ensureIterator() protected method

protected ensureIterator ( ) : Iterator
return Iterator

errorIfOpened() protected method

protected errorIfOpened ( )

getCursorInfo() abstract protected method

abstract protected getCursorInfo ( ) : array
return array

getIterationInfo() protected method

protected getIterationInfo ( ) : array
return array

getOptions() protected method

Applies all options set on the cursor, overwriting any options that have already been set
protected getOptions ( array $optionNames = null ) : array
$optionNames array Array of option names to be applied (will be read from properties)
return array

info() public method

public info ( ) : array

See link: http://www.php.net/manual/en/mongocursor.key.php
public key ( ) : string
return string The current result's _id as a string.

next() public method

Advances the cursor to the next result, and returns that result
See link: http://www.php.net/manual/en/mongocursor.next.php
public next ( ) : array
return array Returns the next object

notImplemented() protected method

protected notImplemented ( )

reset() protected method

public setReadPreference ( string $readPreference, array $tags = null )
$readPreference string
$tags array

storeIteratorState() protected method

This is necessary because hasNext() might advance the iterator but we still need to be able to return the current object.
protected storeIteratorState ( )

timeout() public method

Sets a client-side timeout for this query
See link: http://www.php.net/manual/en/mongocursor.timeout.php
public timeout ( integer $ms )
$ms integer The number of milliseconds for the cursor to wait for a response. By default, the cursor will wait forever.

See link: http://www.php.net/manual/en/mongocursor.valid.php
public valid ( ) : boolean
return boolean If the current result is not null.
