getEncodableMimeTypes

public List<MimeType> getEncodableMimeTypes()

Description copied from interface: Encoder

Return the list of MIME types supported by this Encoder. The list may not apply to every possible target element type and calls to this method should typically be guarded via canEncode(elementType, null). The list may also exclude MIME types supported only for a specific element type. Alternatively, use Encoder.getEncodableMimeTypes(ResolvableType) for a more precise list.

Specified by:

getEncodableMimeTypes in interface Encoder<T>

Returns:

the list of supported MIME types

canEncode

public boolean canEncode(ResolvableType elementType,
                         @Nullable
                         MimeType mimeType)

Description copied from interface: Encoder

Whether the encoder supports the given source element type and the MIME type for the output stream.

Specified by:

canEncode in interface Encoder<T>

Parameters:

elementType - the type of elements in the source stream

mimeType - the MIME type for the output stream (can be null if not specified)

Returns:

true if supported, false otherwise
