IOException

getObjectClass

public Class<T> getObjectClass()

Returns the object class to instantiate.

Returns:

The object class to instantiate.

getObjectMapper

public org.codehaus.jackson.map.ObjectMapper getObjectMapper()

Returns the modifiable Jackson object mapper. Useful to customize mappings.

Returns:

The modifiable Jackson object mapper.

setObject

public void setObject(T object)

Sets the object to format.

Parameters:

object - The object to format.

setObjectClass

public void setObjectClass(Class<T> objectClass)

Sets the object class to instantiate.

Parameters:

objectClass - The object class to instantiate.

setObjectMapper

public void setObjectMapper(org.codehaus.jackson.map.ObjectMapper objectMapper)

Sets the Jackson object mapper.

Parameters:

objectMapper - The Jackson object mapper.
