| Modifier and Type | Method and Description |
|---|---|
boolean |
canRead(java.lang.Class<?> clazz,
MediaType mediaType)
This implementation checks if the given class is supported,
and if the supported media types
include the given media type.
|
boolean |
canRead(java.lang.reflect.Type type,
java.lang.Class<?> contextClass,
MediaType mediaType)
Indicates whether the given type can be read by this converter.
|
boolean |
canWrite(java.lang.Class<?> clazz,
MediaType mediaType)
|
boolean |
canWrite(java.lang.reflect.Type type,
java.lang.Class<?> clazz,
MediaType mediaType)
Indicates whether the given class can be written by this converter.
|
protected MediaType |
getDefaultContentType(java.lang.Object object)
Returns the default content type for the given type.
|
java.lang.Object |
read(java.lang.reflect.Type type,
java.lang.Class<?> contextClass,
HttpInputMessage inputMessage)
Read an object of the given type form the given input message, and returns it.
|
protected ResourceRegion |
readInternal(java.lang.Class<?> clazz,
HttpInputMessage inputMessage)
Abstract template method that reads the actual object.
|
protected void |
writeInternal(java.lang.Object object,
java.lang.reflect.Type type,
HttpOutputMessage outputMessage)
Abstract template method that writes the actual body.

AbstractHttpMessageConverterAbstractHttpMessageConverter.write(T, org.springframework.http.MediaType, org.springframework.http.HttpOutputMessage)
is invoked without a specified content type parameter.
By default, this returns the first element of the
supportedMediaTypes property, if any.
Can be overridden in subclasses.
