Constructor Detail

JsonSourceReader

public JsonSourceReader(java.lang.Class<T> valueType)

Creates a new instance to read the JSON representation of an object. A reader created with this constructor works fine as long as the serialized data to read is not that of an object of generic type; if that is the case, use the other constructor instead.

Parameters:

valueType - the class of the object to read.

Throws:

java.lang.NullPointerException - if any argument is null.

JsonSourceReader

public JsonSourceReader(com.google.gson.reflect.TypeToken<T> valueType)

Creates a new instance to read the JSON representation of an object. Use this constructor when the serialized data to read is that of an object of generic type; if that is not the case, you should use the other constructor instead.

Parameters:

valueType - the generic class of the object to read, e.g. new TypeToken<Optional<Integer>>(){}.

Throws:

java.lang.NullPointerException - if any argument is null.
