java.lang.Object

com.google.gson.TypeAdapter<T>

com.google.gson.internal.bind.TreeTypeAdapter<T>

public final class TreeTypeAdapter<T>
extends TypeAdapter<T>

Adapts a Gson 1.x tree-style adapter as a streaming TypeAdapter. Since the tree adapter may be serialization-only or deserialization-only, this class has a facility to lookup a delegate type adapter on demand.

方法详细资料

read

public T read(JsonReader in)
       throws IOException

从类复制的说明: TypeAdapter

Reads one JSON value (an array, object, string, number, boolean or null) and converts it to a Java object. Returns the converted object.

指定者:

read 在类中 TypeAdapter<T>

返回:

the converted Java object. May be null.

write

public void write(JsonWriter out,
                  T value)

newFactory

public static TypeAdapterFactory newFactory(TypeToken<?> exactType,
                                            Object typeAdapter)

Returns a new factory that will match each type against exactType.

newFactoryWithMatchRawType

public static TypeAdapterFactory newFactoryWithMatchRawType(TypeToken<?> exactType,
                                                            Object typeAdapter)

Returns a new factory that will match each type and its raw type against exactType.

newTypeHierarchyFactory

public static TypeAdapterFactory newTypeHierarchyFactory(Class<?> hierarchyType,
                                                         Object typeAdapter)

Returns a new factory that will match each type's raw type for assignability to hierarchyType.
