Deserialize a primitive JSON value to an object.

Parameters:

primitive - value to deserialize

method - through which the deserialized value will be set on the object

Returns:

the deserialized value

Throws:

IOException - if the setter method to deserialize through does not take exactly one argument, or uses an unhandled numeric type

IllegalAccessException

InvocationTargetException

NoSuchMethodException

deserializePrimitive

public static Object deserializePrimitive(com.fasterxml.jackson.databind.JsonNode primitive,
 Method method,
 Class<?> singularClass)
                                   throws IllegalAccessException,
InvocationTargetException,
NoSuchMethodException,
IOException

Deserialize a primitive JSON value to an object.

Parameters:

primitive - value to deserialize

method - through which the deserialized value will be set on the object

singularClass - class of the first argument (parameter) to the setter method, singularized

Returns:

the deserialized value

Throws:

IOException - if the setter method to deserialize through does not take exactly one argument, or uses an unhandled numeric type

IllegalAccessException

InvocationTargetException

NoSuchMethodException

deserializeNumber

public static Object deserializeNumber(com.fasterxml.jackson.databind.JsonNode primitive,
 Method method)
                                throws IOException

Deserialize a number direct to an object, converting to the correct type.

Parameters:

primitive - number to deserialize

method - through which to the deserialized value will be set on the object

Returns:

the deserialized number

Throws:

IOException - if the setter method to deserialize through does not take exactly one argument, or uses an unhandled numeric type

deserializeString
