Package com.google.protobuf

Class AbstractMessage

  • All Implemented Interfaces:
    Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, MessageOrBuilder
    Direct Known Subclasses:
    DynamicMessage, GeneratedMessage, MapEntry
    public abstract class AbstractMessage
extends com.google.protobuf.AbstractMessageLite
implements Message
    A partial implementation of the Message interface which implements as many methods of that interface as possible in terms of other methods.

    Users should generally ignore this class and use the Message interface instead.

    This class is intended to only be extended by protoc created gencode. It is not intended or supported to extend this class, and any protected methods may be removed without it being considered a breaking change as long as all supported gencode does not depend on the changed methods.

    • Method Detail

      • isInitialized

        public boolean isInitialized()
        Specified by:
        isInitialized in interface com.google.protobuf.MessageLiteOrBuilder

      • findInitializationErrors

        public java.util.List<java.lang.String> findInitializationErrors()
        Description copied from interface: MessageOrBuilder
        Returns a list of field paths (e.g. "foo.bar.baz") of required fields which are not set in this message. You should call MessageLiteOrBuilder.isInitialized() first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.
        Specified by:
        findInitializationErrors in interface MessageOrBuilder

      • getInitializationErrorString

        public java.lang.String getInitializationErrorString()
        Description copied from interface: MessageOrBuilder
        Returns a comma-delimited list of required fields which are not set in this message object. You should call MessageLiteOrBuilder.isInitialized() first to check if there are any missing fields, as that method is likely to be much faster than this one even when the message is fully-initialized.
        Specified by:
        getInitializationErrorString in interface MessageOrBuilder

      • writeTo

        public void writeTo​(com.google.protobuf.CodedOutputStream output)
             throws java.io.IOException
        Specified by:
        writeTo in interface com.google.protobuf.MessageLite
        Throws:
        java.io.IOException

      • getSerializedSize

        public int getSerializedSize()
        Specified by:
        getSerializedSize in interface com.google.protobuf.MessageLite

      • equals

        public boolean equals​(java.lang.Object other)
        Description copied from interface: Message
        Compares the specified object with this message for equality. Returns true if the given object is a message of the same type (as defined by getDescriptorForType()) and has identical values for all of its fields. Subclasses must implement this; inheriting Object.equals() is incorrect.
        Specified by:
        equals in interface Message
        Overrides:
        equals in class java.lang.Object
        Parameters:
        other - object to be compared for equality with this message
        Returns:
        true if the specified object is equal to this message

      • hashCode

        public int hashCode()
        Description copied from interface: Message
        Returns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheriting Object.hashCode() is incorrect.
        Specified by:
        hashCode in interface Message
        Overrides:
        hashCode in class java.lang.Object
        Returns:
        the hash code value for this message
        See Also:
        Map.hashCode()

      • hashFields

        protected static int hashFields​(int hash,
                                java.util.Map<Descriptors.FieldDescriptor,​java.lang.Object> map)
        Get a hash code for given fields and values, using the given seed.
