public class RecursiveToStringStyle extends ToStringStyle
Works with ToStringBuilder
to create a "deep" toString
.
To use this class write code as follows:
public class Job { String title; ... } public class Person { String name; int age; boolean smoker; Job job; ... public String toString() { return new ReflectionToStringBuilder(this, new RecursiveToStringStyle()).toString(); } }
This will produce a toString of the format:
Person@7f54[name=Stephen,age=29,smoker=false,job=Job@43cd2[title=Manager]]
DEFAULT_STYLE, JSON_STYLE, MULTI_LINE_STYLE, NO_CLASS_NAME_STYLE, NO_FIELD_NAMES_STYLE, SHORT_PREFIX_STYLE, SIMPLE_STYLE
