Class Overview
Abstract class that defines the interface that JsonParser and
JsonGenerator use to serialize and deserialize regular
Java objects (POJOs aka Beans).
The standard implementation of this class is
com.fasterxml.jackson.databind.ObjectMapper,
defined in the "jackson-databind".

Public Methods
public abstract TreeNode createArrayNode ()
Method for construct root level Array nodes for Tree Model instances.
public abstract TreeNode createObjectNode ()
Method for construct root level Object nodes for Tree Model instances.
public abstract T readTree (JsonParser jp)
Method to deserialize JSON content as tree expressed
using set of TreeNode instances. Returns
root of the resulting tree (where root can consist
of just a single node if the current event is a
value event, not container).
public abstract T readValue (JsonParser jp, Class<T> valueType)
Method to deserialize JSON content into a non-container
type (it can be an array type, however): typically a bean, array
or a wrapper type (like Boolean).
Note: this method should NOT be used if the result type is a
container (Collection or Map.
The reason is that due to type erasure, key and value types
can not be introspected when using this method.
public abstract T readValue (JsonParser jp, TypeReference<?> valueTypeRef)
Method to deserialize JSON content into a Java type, reference to which is passed as argument. Type is passed using so-called "super type token" and specifically needs to be used if the root type is a parameterized (generic) container type.
public abstract T readValue (JsonParser jp, ResolvedType valueType)
Method to deserialize JSON content into a POJO, type specified
with fully resolved type object (so it can be a generic type,
including containers like Collection and
Map).
public abstract Iterator<T> readValues (JsonParser jp, ResolvedType valueType)
Method for reading sequence of Objects from parser stream, all with same specified value type.
public abstract Iterator<T> readValues (JsonParser jp, TypeReference<?> valueTypeRef)
Method for reading sequence of Objects from parser stream, all with same specified value type.
public abstract Iterator<T> readValues (JsonParser jp, Class<T> valueType)
Method for reading sequence of Objects from parser stream, all with same specified value type.
public abstract JsonParser treeAsTokens (TreeNode n)
Method for constructing a JsonParser for reading
contents of a JSON tree, as if it was external serialized
JSON content.
public abstract T treeToValue (TreeNode n, Class<T> valueType)
Convenience method for converting given JSON tree into instance of specified
value type. This is equivalent to first constructing a JsonParser to
iterate over contents of the tree, and using that parser for data binding.
Throws

public abstract void writeValue (JsonGenerator jgen, Object value)
Method to serialize given Java Object, using generator provided.
