public class ValueWriterLocator extends java.lang.Object
Helper object used for efficient detection of type information relevant to our conversion needs when writing out Java Objects as JSON.Note that usage pattern is such that a single "root" instance is kept by each
JSON
instance; and an actual per-operation instance must be constructed by callingperOperationInstance(com.fasterxml.jackson.jr.ob.impl.JSONWriter, int)
: reason for this is that instances use simple caching to handle the common case of repeating types within JSON Arrays.
