Usage

From source file:org.openschedule.api.impl.AbstractOpenSchedulApiBinding.java

/**
 * Returns a {@link ByteArrayHttpMessageConverter} to be used by the internal {@link RestTemplate} when consuming image or other binary resources.
 * By default, the message converter supports "image/jpeg", "image/gif", and "image/png" media types.
 * Override to customize the message converter (for example, to set supported media types).
 * To remove/replace this or any of the other message converters that are registered by default, override the getMessageConverters() method instead.    
 *//*from w ww  .j a  v  a  2s.c om*/
