`Set<Map.Entry<String, byte[]>>`	`entrySet()` Returns the set of metadata entries in their raw byte array form.
`boolean`	`equals(@Nullable Object o)`
`final @Nullable byte[]`	`get(String key, @Nullable byte[] defaultValue)` Returns a metadata value.
`final long`	`get(String key, long defaultValue)` Returns a metadata value.
`final @Nullable String`	`get(String key, @Nullable String defaultValue)` Returns a metadata value.
`int`	`hashCode()`

`static final String`	`KEY_CONTENT_LENGTH = "exo_len"` Key for content length in bytes (type: long).
`static final String`	`KEY_CUSTOM_PREFIX = "custom_"` Prefix for custom metadata keys.
`static final String`	`KEY_REDIRECTED_URI = "exo_redir"` Key for redirected uri (type: String).

`static long`	`getContentLength(ContentMetadata contentMetadata)` Returns the value stored under `KEY_CONTENT_LENGTH`, or `LENGTH_UNSET` if not set.
`static @Nullable Uri`	`getRedirectedUri(ContentMetadata contentMetadata)` Returns the value stored under `KEY_REDIRECTED_URI` as a `Uri`, or {code null} if not set.

Returns a metadata value.

Parameters
`String key`	Key of the metadata to be returned.
`@Nullable byte[] defaultValue`	Value to return if the metadata doesn't exist.

Returns
`@Nullable byte[]`	The metadata value.

public final long get(String key, long defaultValue)

Returns a metadata value.

Parameters
`String key`	Key of the metadata to be returned.

`long`	The metadata value.

public final @Nullable String get(String key, @Nullable String defaultValue)

Returns a metadata value.

Parameters
`String key`	Key of the metadata to be returned.
`@Nullable String defaultValue`	Value to return if the metadata doesn't exist.

Returns
`@Nullable String`	The metadata value.
