               Class<?> elementType)

Convert the source to be the multiple value

参数:

source - the source-typed value

multiValueType - the multi-value type

elementType - the element type

返回:

getSourceType

default Class<S> getSourceType()

Get the source type

返回:

non-null

find

static MultiValueConverter<?> find(Class<?> sourceType,
                                   Class<?> targetType)
