Description copied from interface: IFastJsonConverter

Serializes the given instance to a JSON object.

Specified by:

toJsonObject in interface IFastJsonConverter

Parameters:

data - The data object to serialize.

Returns:

A JSON object with the data from the given object.

Throws:

FastJsonException - When the JSON could not be serialized.

toJsonString

public String toJsonString(Object data)
                    throws FastJsonException

Description copied from interface: IFastJsonConverter

Serializes the given instance to a JSON string.

Specified by:

toJsonString in interface IFastJsonConverter

Parameters:

data - The data object to serialize.

Returns:

A JSON string that represents the serialized form of the given data.

Throws:

forClassLoader

public static IFastJsonConverter forClassLoader(ClassLoader loader)

Parameters:

loader - Class loader to use for locating classes during deserialization.

Returns:

An (effectively) immutable IFastJsonConverter instance with the given class loader.

Throws:

NullPointerException - When loader is null.

forClassLoaderCached

public static IFastJsonConverter forClassLoaderCached(ClassLoader loader)

Same as forClassLoader, but reuses created instances if possible. Not that since the returned converter is effectively immutable, there is no functional difference between this method and forClassLoader.

Parameters:

loader - Class loader to use for locating classes during deserialization.

Returns:

An (effectively) immutable IFastJsonConverter instance with the given class loader.

Throws:

NullPointerException - When loader is null.
