flat_static_buffer_base

A dynamic buffer using a fixed size internal buffer.

Synopsis

Defined in header <boost/beast/core/flat_static_buffer.hpp>

class flat_static_buffer_base
Types

Name

Description

const_buffers_type

Member Functions

Name

Description

capacity

Return the maximum number of bytes, both readable and writable, that can be held without requiring an allocation.

cdata

Returns a constant buffer sequence representing the readable bytes.

clear

Clear the readable and writable bytes to zero.

commit

Append writable bytes to the readable bytes.

consume

Remove bytes from beginning of the readable bytes.

data

Returns a constant buffer sequence representing the readable bytes.

Returns a mutable buffer sequence representing the readable bytes.

flat_static_buffer_base

Constructor.

max_size

Return the maximum number of bytes, both readable and writable, that can ever be held.

prepare

Returns a mutable buffer sequence representing writable bytes.

size

flat_static_buffer_base

Constructor.

reset

Reset the pointed-to buffer.

Description

A dynamic buffer encapsulates memory storage that may be automatically resized as required, where the memory is divided into two regions: readable bytes followed by writable bytes. These memory regions are internal to the dynamic buffer, but direct access to the elements is provided to permit them to be efficiently used with I/O operations. Objects of this type meet the requirements of DynamicBuffer and have the following additional properties:

Remarks

Variables are usually declared using the template class flat_static_buffer; however, to reduce the number of template instantiations, objects should be passed flat_static_buffer_base&.
