Method Detail

setProcessExternalEntities

public void setProcessExternalEntities(boolean processExternalEntities)

Indicates whether external XML entities are processed when converting to a Source.

Default is false, meaning that external entities are not resolved.

canRead

public boolean canRead(Class<?> clazz,
              MediaType mediaType)

Description copied from class: AbstractHttpMessageConverter

This implementation checks if the given class is supported, and if the supported media types include the given media type.

Specified by:

canRead in interface HttpMessageConverter<Object>

Overrides:

canRead in class AbstractHttpMessageConverter<Object>

Parameters:

clazz - the class to test for readability

mediaType - the media type to read, can be null if not specified. Typically the value of a Content-Type header.

Returns:

true if readable; false otherwise

canWrite

public boolean canWrite(Class<?> clazz,
               MediaType mediaType)

Description copied from class: AbstractHttpMessageConverter

This implementation checks if the given class is supported, and if the supported media types include the given media type.

Specified by:

canWrite in interface HttpMessageConverter<Object>

Overrides:

canWrite in class AbstractHttpMessageConverter<Object>

Parameters:

clazz - the class to test for writability

mediaType - the media type to write, can be null if not specified. Typically the value of an Accept header.

Returns:

true if writable; false otherwise

supports

protected boolean supports(Class<?> clazz)

Description copied from class: AbstractHttpMessageConverter

Indicates whether the given class is supported by this converter.

Specified by:

supports in class AbstractHttpMessageConverter<Object>

Parameters:

clazz - the class to test for support

Returns:

true if supported; false otherwise

readFromSource

protected Object readFromSource(Class<?> clazz,
                    HttpHeaders headers,
