Method Summary

Modifier and Type	Method and Description
default void	metadataToExtract(org.springframework.util.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(org.springframework.util.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(org.springframework.util.MimeType mimeType, org.springframework.core.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(org.springframework.util.MimeType mimeType, org.springframework.core.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.

Method Detail

metadataToExtract

default void metadataToExtract(org.springframework.util.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(org.springframework.util.MimeType mimeType,
                               org.springframework.core.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(org.springframework.util.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

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
