Class com.fasterxml.jackson.core.ObjectCodec

Examples of com.fasterxml.jackson.core.ObjectCodec.readTree()

com.fasterxml.jackson.core.ObjectCodec.readTree()
Method to deserialize JSON content as tree expressed using set of {@link TreeNode} instances. Returnsroot of the resulting tree (where root can consist of just a single node if the current event is a value event, not container). Empty or whitespace documents return null. @return next tree from jp, or null if empty.
