}

Creates a new entity with the given content, content type, and charset.

Parameters:

content - The content to set.

contentType - The type of the content, or null. The value retured by #getContentType() . If this content type contains a charset and the charset parameter is null, the content's type charset will be used.

charset - The charset of the content, or null. Used to convert the content to bytes. If the content type does not contain a charset and charset is not null, then the charset will be appended to the content type.
