                                           int... fieldNumbers)

  Constructs a FieldMask from the passed field numbers.

  Throws:

  java.lang.IllegalArgumentException - if any of the fields are invalid for the message.

• fromFieldNumbers

  public static FieldMask fromFieldNumbers(java.lang.Class<? extends Message> type,
                                           java.lang.Iterable<java.lang.Integer> fieldNumbers)

  Throws:

  java.lang.IllegalArgumentException - if any of the fields are invalid for the message.

• toJsonString

  public static java.lang.String toJsonString(FieldMask fieldMask)

  Converts a field mask to a Proto3 JSON string, that is converting from snake case to camel case and joining all paths into one string with commas.

• fromJsonString

  public static FieldMask fromJsonString(java.lang.String value)

  Converts a field mask from a Proto3 JSON string, that is splitting the paths along commas and converting from camel case to snake case.

• isValid

  public static boolean isValid(java.lang.Class<? extends Message> type,
                                FieldMask fieldMask)

  Checks whether paths in a given fields mask are valid.

• isValid

  public static boolean isValid(Descriptors.Descriptor descriptor,
                                FieldMask fieldMask)

  Checks whether paths in a given fields mask are valid.

• isValid

  public static boolean isValid(java.lang.Class<? extends Message> type,
                                java.lang.String path)

  Checks whether a given field path is valid.

• isValid

  public static boolean isValid(Descriptors.Descriptor descriptor,
                                java.lang.String path)

  Checks whether paths in a given fields mask are valid.

• normalize

  public static FieldMask normalize(FieldMask mask)

  Converts a FieldMask to its canonical form. In the canonical form of a FieldMask, all field paths are sorted alphabetically and redundant field paths are removed.

• union

  public static FieldMask union(FieldMask firstMask,
                                FieldMask secondMask,
                                FieldMask... otherMasks)

  Creates a union of two or more FieldMasks.

• subtract

  public static FieldMask subtract(FieldMask firstMask,
                                   FieldMask secondMask,
                                   FieldMask... otherMasks)

  Subtracts secondMask and otherMasks from firstMask.

  This method disregards proto structure. That is, if firstMask is "foo" and secondMask is "foo.bar", the response will always be "foo" without considering the internal proto structure of message "foo".

• intersection

  public static FieldMask intersection(FieldMask mask1,
                                       FieldMask mask2)

  Calculates the intersection of two FieldMasks.

• merge

  public static void merge(FieldMask mask,
                           Message source,
                           Message.Builder destination,
                           FieldMaskUtil.MergeOptions options)

  Merges fields specified by a FieldMask from one message to another with the specified merge options. The destination will remain unchanged if an empty FieldMask is provided.

• merge

  public static void merge(FieldMask mask,
                           Message source,
                           Message.Builder destination)

  Merges fields specified by a FieldMask from one message to another.
