Public Methods

Method	Description
__construct ( )
isDisallowedOperation ( Predis\Command\CommandInterface $command ) : boolean	Returns if the specified command is not allowed for execution in a master slave replication context.
isReadOperation ( Predis\Command\CommandInterface $command ) : boolean	Returns if the specified command will perform a read-only operation on Redis or not.
setCommandReadOnly ( string $commandID, mixed $readonly = true )	Marks a command as a read-only operation.
setScriptReadOnly ( string $script, mixed $readonly = true )	Marks a Lua script for EVAL and EVALSHA as a read-only operation. When the behaviour of a script can be decided only at runtime depending on its arguments, a callable object can be provided to dynamically check if the passed instance of EVAL or EVALSHA performs write operations or not.

Protected Methods

Method	Description
getDisallowedOperations ( ) : array	Returns the default list of disallowed commands.
getReadOnlyOperations ( ) : array	Returns the default list of commands performing read-only operations.
isBitfieldReadOnly ( Predis\Command\CommandInterface $command ) : boolean	Checks if BITFIELD performs a read-only operation by looking for certain SET and INCRYBY modifiers in the arguments array of the command.
isGeoradiusReadOnly ( Predis\Command\CommandInterface $command ) : boolean	Checks if a GEORADIUS command is a readable operation by parsing the arguments array of the specified commad instance.
isSortReadOnly ( Predis\Command\CommandInterface $command ) : boolean	Checks if a SORT command is a readable operation by parsing the arguments array of the specified commad instance.
