org.apache.commons.lang3.builder.ToStringStyle.JsonToStringStyle

All Implemented Interfaces:

Serializable

Enclosing class:

ToStringStyle

private static final class ToStringStyle.JsonToStringStyle
extends ToStringStyle

ToStringStyle that outputs with JSON format.

This is an inner class rather than using StandardToStringStyle to ensure its immutability.
