Methods summary

`public`	# `__construct( Core\Storage $driver, Core\Storage\Accessor_Node $query )` Internal method to initialise a new prepared storage statement. Internal method to initialise a new prepared storage statement. Parameters `$driver` Reference to the specific storage driver interface for the prepared statement. `$query` Accessor node to transform into storage-specific query statement. Since 3.0
`public string`	# `__toString( )` Formats the statement type class name including the query string. Useful for debug output. Formats the statement type class name including the query string. Useful for debug output. Returns string String containing statement type class and query string. Since 3.0 Overrides `Core\Object::__toString`
`protected string`	# `_bind( string $name, mixed $value = null )` Establishes private binding and returns »?«, the standard marker for parameters. Storage engines that use different markers should overwrite this method and call the parent method to establish bindings but return a different marker. Establishes private binding and returns »?«, the standard marker for parameters. Storage engines that use different markers should overwrite this method and call the parent method to establish bindings but return a different marker. Parameters `$name` Name of parameter to bind. `$value` Value to bind. Returns string Bound parameter indicator. Since 3.1
`protected string`	# `_transform( $node )` Accessor transformation hub. Transforms a given accessor node into the driver-specific format by calling transformation methods for each accessor node recursively. Accessor transformation hub. Transforms a given accessor node into the driver-specific format by calling transformation methods for each accessor node recursively. Parameters `$node` node to transform. Returns string Transformed query statement data specific to the current driver. Throws `Core\Exception\Storage` Encountered an accessor node class that is not supported by the driver. Since 3.0
`protected string`	# `_transform_Boolean( boolean $value )` Default transformation for Boolean values. Default transformation for Boolean values. Parameters `$value` Boolean value to transform. Returns string Returns the string »0«, if value is `false`, otherwise »1«. Since 3.0
`protected string`	# `_transform_Core_Storage_Accessor_Parameter( Core\Storage\Accessor_Parameter $parameter )` Registers a dynamic binding for the parameter provided. Registers a dynamic binding for the parameter provided. Parameters `$parameter` Parameter object to transform. Returns string Binding indicator. Since 3.1
`protected string`	# `_transform_Float( float $value )` Default transformation for floating point values. Default transformation for floating point values. Parameters `$value` Decimal number to transform. Returns string Returns the default C-style to-string conversion of the value. Since 3.0
`protected string`	# `_transform_Identifier( string $name )` Escapes identifiers as required by the storage back-end. Escapes identifiers as required by the storage back-end. Parameters `$name` Identifier to escape. Returns string Escaped identifier string. Remark The default implementation uses SQL'92 identifiers. Drivers should implement the corresponding syntax required by their back-end. Since 3.0
`protected string`	# `_transform_Integer( integer $value )` Default transformation for integer values. Default transformation for integer values. Parameters `$value` Scalar integer number to transform. Returns string Returns the default PHP to-string conversion of the value. Since 3.0
`protected string`	# `_transform_Storable( Core\Storable $object )` Default transformation for objects implementing the `Core\Storable` interface. Default transformation for objects implementing the `Core\Storable` interface. Parameters `$object` Storable object to transform. Returns string Returns the packed variant from the `Core\Storable` object. Since 3.1
`protected string`	# `_transform_String( string $string )` Default transformation for strings. Default transformation for strings. Parameters `$string` String to transform. Returns string Returns the string verbatim. Since 3.0
`public Core\Storage_Result`	# `execute( array $parameters = null )` Executes the prepared statement of the current instance. Executes the prepared statement of the current instance. Parameters `$parameters` Optional. Associative key-value arguments array for execution control passed on to the driver Storage::execute() method. Returns `Core\Storage_Result` Storage result set on success, otherwise an exception is thrown. Since 3.0
`public array`	# `mergeParameters( array $parameters = null )` Merges internal parameters sets with external sets. If no external set is given, external parameters are initialised with `null`. Merges internal parameters sets with external sets. If no external set is given, external parameters are initialised with `null`. Parameters `$parameters` Parameters array to merge into internal parameters array. Returns array Bindings array. Throws `Core\Exception\InvalidArgument` Argument key contains an unknown parameter name. Since 3.1
