    • setNestedPath

      public void setNestedPath(@Nullable String nestedPath)
      Description copied from interface: Errors
      Allow context to be changed so that standard validators can validate subtrees. Reject calls prepend the given path to the field names.

      For example, an address validator could validate the subobject "address" of a customer object.

      Specified by:
      setNestedPath in interface Errors
      Parameters:
      nestedPath - nested path within this object, e.g. "address" (defaults to "", null is also acceptable). Can end with a dot: both "address" and "address." are valid.
      See Also:

    • getNestedPath

      public String getNestedPath()
      Description copied from interface: Errors
      Return the current nested path of this Errors object.

      Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.

      Specified by:
      getNestedPath in interface Errors
      See Also:

    • pushNestedPath

      public void pushNestedPath(String subPath)
      Description copied from interface: Errors
      Push the given sub path onto the nested path stack.

      A Errors.popNestedPath() call will reset the original nested path before the corresponding pushNestedPath(String) call.

      Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.

      For example: current path "spouse.", pushNestedPath("child") → result path "spouse.child."; popNestedPath() → "spouse." again.

      Specified by:
      pushNestedPath in interface Errors
      Parameters:
      subPath - the sub path to push onto the nested path stack
      See Also:

    • popNestedPath

      public void popNestedPath() throws IllegalStateException
      Description copied from interface: Errors
      Pop the former nested path from the nested path stack.
      Specified by:
      popNestedPath in interface Errors
      Throws:
      IllegalStateException - if there is no former nested path on the stack
      See Also:

    • doSetNestedPath

      protected void doSetNestedPath(@Nullable String nestedPath)
      Actually set the nested path. Delegated to by setNestedPath and pushNestedPath.

    • fixedField

      protected String fixedField(@Nullable String field)
      Transform the given field into its full path, regarding the nested path of this instance.

    • canonicalFieldName

      protected String canonicalFieldName(String field)
      Determine the canonical field name for the given field.

      The default implementation simply returns the field name as-is.

      Parameters:
      field - the original field name
      Returns:
      the canonical field name

    • reject

      public void reject(String errorCode)
      Description copied from interface: Errors

      Specified by:
      reject in interface Errors
      Parameters:
      errorCode - error code, interpretable as a message key
      See Also:

    • reject

      public void reject(String errorCode, String defaultMessage)
      Description copied from interface: Errors
      Register a global error for the entire target object, using the given error description.
      Specified by:

    • rejectValue

      public void rejectValue(@Nullable String field, String errorCode)
      Description copied from interface: Errors
      Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.

      The field name may be null or empty String to indicate the current object itself rather than a field of it. This may result in a corresponding field error within the nested object graph or a global error if the current object is the top object.

      Specified by:
      rejectValue in interface Errors
      Parameters:
      field - the field name (may be null or empty String)
      errorCode - error code, interpretable as a message key

      Description copied from interface: Errors
      Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.

      The field name may be null or empty String to indicate the current object itself rather than a field of it. This may result in a corresponding field error within the nested object graph or a global error if the current object is the top object.

      Specified by:
      rejectValue in interface Errors
      Parameters:
      field - the field name (may be null or empty String)
