Class FieldSet<T extends FieldSet.FieldDescriptorLite<T>>

    • Constructor Detail

      • FieldSet

        private FieldSet()
        Construct a new FieldSet.

      • FieldSet

        private FieldSet​(boolean dummy)
        Construct an empty FieldSet. This is only used to initialize DEFAULT_INSTANCE.

      • FieldSet

        private FieldSet​(SmallSortedMap<T,​java.lang.Object> fields)

    • Method Detail

      • isEmpty

        boolean isEmpty()
        Returns true if empty, false otherwise.

      • makeImmutable

        public void makeImmutable()
        Make this FieldSet immutable from this point forward.

      • isImmutable

        public boolean isImmutable()
        Returns whether the FieldSet is immutable. This is true if it is the emptySet() or if makeImmutable() were called.
        Returns:
        whether the FieldSet is immutable.

      • equals

        public boolean equals​(java.lang.Object o)
        Overrides:
        equals in class java.lang.Object

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object

      • clone

        public FieldSet<T> clone()
        Clones the FieldSet. The returned FieldSet will be mutable even if the original FieldSet was immutable.
        Overrides:
        clone in class java.lang.Object
        Returns:
        the newly cloned FieldSet

      • getAllFields

        public java.util.Map<T,​java.lang.Object> getAllFields()
        Get a simple map containing all the fields.

      • cloneFieldEntry

        private static <T extends FieldSet.FieldDescriptorLite<T>> void cloneFieldEntry​(java.util.Map<T,​java.lang.Object> map,
                                                                                java.util.Map.Entry<T,​java.lang.Object> entry,
                                                                                boolean copyList,

      • iterator

        public java.util.Iterator<java.util.Map.Entry<T,​java.lang.Object>> iterator()
        Get an iterator to the field map. This iterator should not be leaked out of the protobuf library as it is not protected from mutation when fields is not immutable.

      • descendingIterator

        java.util.Iterator<java.util.Map.Entry<T,​java.lang.Object>> descendingIterator()
        Get an iterator over the fields in the map in descending (i.e. reverse) order. This iterator should not be leaked out of the protobuf library as it is not protected from mutation when fields is not immutable.

      • verifyType

        private void verifyType​(T descriptor,
                        java.lang.Object value)
        Verifies that the given object is of the correct type to be a valid value for the given field. (For repeated fields, this checks if the object is the right type to be one element of the field.)
        Throws:
        java.lang.IllegalArgumentException - the value is not of the right type

      • isValidType

      • isInitialized

        public boolean isInitialized()
        See MessageLiteOrBuilder.isInitialized(). Note: Since FieldSet itself does not have any way of knowing about required fields that aren't actually present in the set, it is up to the caller to check that all required fields are present.

      • isInitialized

        private static <T extends FieldSet.FieldDescriptorLite<T>> boolean isInitialized​(java.util.Map.Entry<T,​java.lang.Object> entry)

                                     boolean isPacked)
        Given a field type, return the wire type.
