All Known Implementing Classes:
DefaultMetadataExtractor
```
public interface MetadataExtractorRegistry
```
Stores registrations of extractors for metadata entries. Each metadata entry is decoded based on its MimeType and a name is assigned to the decoded value.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`metadataToExtract(MimeType mimeType, Class<?> targetType, String name)`	Decode metadata entries with the given `MimeType` to the specified target class, and store the decoded value in the output map under the given name.
`<T> void`	`metadataToExtract(MimeType mimeType, Class<T> targetType, BiConsumer<T,Map<String,Object>> mapper)`	Variant of `metadataToExtract(MimeType, Class, String)` that allows custom logic to be used to map the decoded value to any number of values in the output map.
`default void`	`metadataToExtract(MimeType mimeType, ParameterizedTypeReference<?> targetType, String name)`	Variant of `metadataToExtract(MimeType, Class, String)` that accepts `ParameterizedTypeReference` instead of `Class` for specifying a target type with generic parameters.
`<T> void`	`metadataToExtract(MimeType mimeType, ParameterizedTypeReference<T> type, BiConsumer<T,Map<String,Object>> mapper)`	Variant of `metadataToExtract(MimeType, Class, BiConsumer)` that accepts `ParameterizedTypeReference` instead of `Class` for specifying a target type with generic parameters.

default void metadataToExtract(MimeType mimeType,
                               Class<?> targetType,
                               @Nullable
                               String name)
```
    Decode metadata entries with the given MimeType to the specified target class, and store the decoded value in the output map under the given name.
    Parameters:
    mimeType - the mime type of metadata entries to extract
    targetType - the target value type to decode to
    name - assign a name for the decoded value; if not provided, then the mime type is used as the key
  - metadataToExtract
```
default void metadataToExtract(MimeType mimeType,
                               ParameterizedTypeReference<?> targetType,
                               @Nullable
                               String name)
```
    Variant of metadataToExtract(MimeType, Class, String) that accepts ParameterizedTypeReference instead of Class for specifying a target type with generic parameters.
    Parameters:
    mimeType - the mime type of metadata entries to extract
    targetType - the target value type to decode to
  - metadataToExtract
```
<T> void metadataToExtract(MimeType mimeType,
                           Class<T> targetType,
                           BiConsumer<T,Map<String,Object>> mapper)
```
    Variant of metadataToExtract(MimeType, Class, String) that allows custom logic to be used to map the decoded value to any number of values in the output map.
    Type Parameters:
    T - the target value type
    Parameters:
    mimeType - the mime type of metadata entries to extract
    targetType - the target value type to decode to
    mapper - custom logic to add the decoded value to the output map
  - metadataToExtract
```
<T> void metadataToExtract(MimeType mimeType,
                           ParameterizedTypeReference<T> type,
                           BiConsumer<T,Map<String,Object>> mapper)
```
    Variant of metadataToExtract(MimeType, Class, BiConsumer) that accepts ParameterizedTypeReference instead of Class for specifying a target type with generic parameters.
    Type Parameters:
    T - the target value type
    Parameters:
    mimeType - the mime type of metadata entries to extract
    type - the target value type to decode to
    mapper - custom logic to add the decoded value to the output map
