Pipable

Description

A Pipable Filter can appear as a component of a pipline.

Certian overloads of operator| must be defined to make a Filter Pipable; this is achieved by invoking the macro BOOST_IOSTREAMS_PIPABLE.

Refinement of

Filter.

Associated Types

Same as Filter.

Notation

| P | - | A type which is a model of Pipable | | C | - | A type which is a model of Filter or Device and which is CopyConstructible[1] | | p | - | Object of type P | | c | - | Object of type C |

Valid Expressions / Semantics

f | c

| implementation-defined | Returns a pipeline corresponding to the sequence f, c |

Models

• All the Filters provided by the Iostreams library.

[1]This requirement prevents streams and stream buffers from appearing in pipelines without the use of reference wrappers. This restriction may be removed in a future version of the Iostreams library.
