question: whether to replace primitive non-repeated and non-message fields in destination message fields with the source primitive fields i.e. , if the field is set in the source , the value is copied to the destination ; if the field is unset in the source , the field is cleared from the destination when merging . default behavior is to always set the value of the source primitive field to the destination primitive field , and if the source field is unset , the default value of the source field is copied to the destination . concode_field_sep String FIELD_SEPARATOR_REGEX concode_elem_sep String FIELD_PATH_SEPARATOR concode_elem_sep String FIELD_PATH_SEPARATOR_REGEX concode_elem_sep boolean replacePrimitiveFields concode_elem_sep boolean replaceMessageFields concode_elem_sep boolean replaceRepeatedFields concode_field_sep boolean isValid concode_elem_sep boolean isValid concode_elem_sep boolean isValid concode_elem_sep boolean isValid concode_elem_sep boolean replaceMessageFields concode_elem_sep FieldMask fromFieldNumbers concode_elem_sep FieldMask fromFieldNumbers concode_elem_sep FieldMask union concode_elem_sep void setReplaceMessageFields concode_elem_sep FieldMask fromStringList concode_elem_sep void setReplaceRepeatedFields concode_elem_sep FieldMask normalize concode_elem_sep FieldMask intersection concode_elem_sep void merge concode_elem_sep void merge concode_elem_sep String toString concode_elem_sep FieldMask fromString concode_elem_sep FieldMask fromString concode_elem_sep boolean replaceRepeatedFields concode_elem_sep void setReplacePrimitiveFields
