Enclosing class:

JsonWriter

public static interface JsonWriter.JsonClassWriter

Implement this interface to customize the JSON output for a given class.

Method Summary

Modifier and Type	Method	Description
default String	getTypeName(Object o)
default boolean	hasPrimitiveForm(WriterContext context)
default void	write(Object o, boolean showType, Writer output, WriterContext context)	When write() is called, it is expected that subclasses will write the appropriate JSON to the passed in Writer.
default void	writePrimitiveForm(Object o, Writer output, WriterContext context)	This default implementation will call the more basic writePrimitiveForm that does not take arguments.

Method Details

write

default void write(Object o,
 boolean showType,
 Writer output,
 WriterContext context)
            throws IOException

When write() is called, it is expected that subclasses will write the appropriate JSON to the passed in Writer.

Parameters:

o - Object to be written in JSON format.

showType - boolean indicating whether to show @type.

output - Writer destination to where the actual JSON is written.

context - WriterContext to get writeOptions and other write access

Throws:

IOException - if thrown by the writer. Will be caught at a higher level and wrapped in JsonIoException.

hasPrimitiveForm

default boolean hasPrimitiveForm(WriterContext context)

Parameters:

context - WriterContext to get writeOptions and other write access

Returns:

boolean true if the class being written has a primitive (non-object) form. Default is false since most custom writers will not have a primitive form.

writePrimitiveForm

default void writePrimitiveForm(Object o,
 Writer output,
 WriterContext context)
                         throws IOException

This default implementation will call the more basic writePrimitiveForm that does not take arguments. No need to override this method unless you need access to the args.

Parameters:

o - Object to be written

output - Writer destination to where the actual JSON is written.

context - WriterContext to get access to writeOptions and writing tools

Throws:

IOException - if thrown by the writer. Will be caught at a higher level and wrapped in JsonIoException.

getTypeName

default String getTypeName(Object o)
