explicit
seekable_input_resource (
    std::size_t buffer_capacity = io_buffer::default_buffer_capacity
)

Constructs a seekable input resource with the given buffer capacity.

Parameters:
  • buffer_capacity:

    The capacity of the I/O buffer. If this is zero, the seekable input resource is completely unbuffered.

seekable_input_resource (
    const seekable_input_resource& other
)

Copy-constructs a seekable_input_resource from an existing one.

Parameters:
  • other:

    The seekable_input_resource to copy from.

seekable_input_resource&
operator = (
    const seekable_input_resource& other
)

Copy-assigns a seekable_input_resource into this one.

Parameters:
  • other:

    The seekable_input_resource to copy from.

seekable_input_resource (
    seekable_input_resource&& other
)
noexcept

Move-constructs a seekable_input_resource from an existing one.

Parameters:
  • other:

    The seekable_input_resource to move from.

seekable_input_resource&
operator = (
    seekable_input_resource&& other
)
noexcept

Move-assigns a seekable_input_resource into this one.

Parameters:
  • other:

    The seekable_input_resource to move from.

void
set_position (
    position_type new_position,
    position_reference pr
)
noexcept override

Sets the position of this seekable input resource.

Parameters:
  • new_position:

    The new position of this seekable input resource.

  • pr:

    The reference that the new position is relative to.
