# FLAC::Metadata::Unknown Class Reference
[FLAC++/metadata.h: metadata object classes]

`#include <metadata.h>`

Inheritance diagram for FLAC::Metadata::Unknown:

List of all members.

## Detailed Description

Opaque metadata block for storing unknown types. This should not be used unless you know what you are doing; it is currently used only internally to support forward compatibility of metadata blocks. See the overview for more,

## Constructor & Destructor Documentation

FLAC::Metadata::Unknown::Unknown | ( | const Unknown & | object | ) | `[inline]`

| Constructs a copy of the given object. This form always performs a deep copy.

FLAC::Metadata::Unknown::Unknown | ( | ::FLAC__StreamMetadata * | object,
|  | bool | copy
| ) | `[inline]`

| Constructs an object with copy control. See Prototype(::FLAC__StreamMetadata *object, bool copy).

## Member Function Documentation

Unknown& FLAC::Metadata::Unknown::operator= | ( | const Unknown & | object | ) | `[inline]`

| Assign from another object. Always performs a deep copy.

Unknown& FLAC::Metadata::Unknown::assign | ( | ::FLAC__StreamMetadata * | object,
|  | bool | copy
| ) | `[inline]`

| Assigns an object with copy control. See Prototype::assign_object(::FLAC__StreamMetadata *object, bool copy).

bool FLAC::Metadata::Unknown::operator== | ( | const Unknown & | object | ) | const`[inline]`

| Check for equality, performing a deep compare by following pointers.

bool FLAC::Metadata::Unknown::operator!= | ( | const Unknown & | object | ) | const`[inline]`

| Check for inequality, performing a deep compare by following pointers.

bool FLAC::Metadata::Unknown::set_data | ( | const FLAC__byte * | data,
|  | unsigned | length
| ) |

| This form always copies data.

Prototype& FLAC::Metadata::Prototype::assign_object | ( | ::FLAC__StreamMetadata * | object,
|  | bool | copy
| ) | `[protected, inherited]`

| Assigns an object with copy control. See Prototype(::FLAC__StreamMetadata *object, bool copy).

virtual void FLAC::Metadata::Prototype::clear | ( |  | ) | `[protected, virtual, inherited]`

| Deletes the underlying FLAC__StreamMetadata object.

bool FLAC::Metadata::Prototype::get_is_last | ( |  | ) | const`[inherited]`

  | Returns `true` if this block is the last block in a stream, else `false`. Assertions:
       is_valid()

::FLAC__MetadataType FLAC::Metadata::Prototype::get_type | ( |  | ) | const`[inherited]`

  | Returns the type of the block. Assertions:
       is_valid()
Reimplemented in FLAC::Metadata::Picture.

unsigned FLAC::Metadata::Prototype::get_length | ( |  | ) | const`[inherited]`

  | Returns the stream length of the metadata block. Note: The length does not include the metadata block header, per spec. Assertions:
       is_valid()

void FLAC::Metadata::Prototype::set_is_last | ( | bool |  | ) | `[inherited]`

  | Sets the "is_last" flag for the block. When using the iterators it is not necessary to set this flag; they will do it for you. Assertions:
       is_valid()
