  • Element Details

    • includeFieldNames

      boolean includeFieldNames
      Include the name of each field when printing it. default: true
      Returns:
      Whether or not to include the names of fields in the string produced by the generated toString().
      Default:
      true
    • exclude

      java.lang.String[] exclude
      Any fields listed here will not be printed in the generated toString implementation. Mutually exclusive with of().

      Will soon be marked @Deprecated; use the @ToString.Exclude annotation instead.

      Returns:
      A list of fields to exclude.
      Default:
      {}
    • of

      java.lang.String[] of
      If present, explicitly lists the fields that are to be printed. Normally, all non-static fields are printed.

      Mutually exclusive with exclude().

      Will soon be marked @Deprecated; use the @ToString.Include annotation together with @ToString(onlyExplicitlyIncluded = true).

      Returns:
      A list of fields to use (default: all of them).
      Default:
      {}
    • callSuper

      boolean callSuper
      Include the result of the superclass's implementation of toString in the output. default: false
      Returns:
      Whether to call the superclass's toString implementation as part of the generated toString algorithm.
      Default:
      false
    • doNotUseGetters

      boolean doNotUseGetters
      Normally, if getters are available, those are called. To suppress this and let the generated code use the fields directly, set this to true. default: false
      Returns:
      If true, always use direct field access instead of calling the getter method.
      Default:
      false
    • onlyExplicitlyIncluded

      boolean onlyExplicitlyIncluded
      Only include fields and methods explicitly marked with @ToString.Include. Normally, all (non-static) fields are included by default.
      Returns:
      If true, don't include non-static fields automatically (default: false).
      Default:
      false
