        Description copied from interface: GraphInput
        Updates the last reference (the tip/end of the index) kept if the lastMessage was indeed the last message.
        Specified by:
        updateLast in interface GraphInput

      • isCurrentMessageReference

        public boolean isCurrentMessageReference()
        Description copied from interface: GraphInput
        Returns true if the last message was read as a reference.

      • mergeObject

        public <T> T mergeObject​(T value,

                  throws java.io.IOException
        Description copied from interface: Input
        Merges an object(with schema) field value. The provided schema handles the deserialization for the object.
        Specified by:
        mergeObject in interface Input
        Overrides:
        mergeObject in class FilterInput<CodedInput>
        Throws:
        java.io.IOException

      • handleUnknownField

        public <T> void handleUnknownField​(int fieldNumber,
                                   Schema<T> schema)
                            throws java.io.IOException
        Description copied from interface: Input
        The underlying implementation should handle the unknown field.
        Specified by:
        handleUnknownField in interface Input
        Overrides:
        handleUnknownField in class FilterInput<CodedInput>
        Throws:
        java.io.IOException

      • getFieldName

        public java.lang.String getFieldName​(int number)
        Description copied from interface: Schema
        Gets the field name associated with the number. This is particularly useful when serializing to different formats (Eg. JSON). When using numeric field names: 
         return String.valueOf(number);
        Specified by:
        getFieldName in interface Schema<java.lang.Object>

      • getFieldNumber

        public int getFieldNumber​(java.lang.String name)
        Description copied from interface: Schema
        Gets the field number associated with the name. This is particularly useful when serializing to different formats (Eg. JSON). When using numeric field names: 
         return Integer.parseInt(name);
        Specified by:
        getFieldNumber in interface Schema<java.lang.Object>

      • isInitialized

        public boolean isInitialized​(java.lang.Object owner)
        Description copied from interface: Schema
        Returns true if there is no required field or if all the required fields are set.

        Returns the full name of the message tied to this schema. Allows custom schemas to provide a custom name other than typeClass().getName();
        Specified by:
        messageFullName in interface Schema<java.lang.Object>

      • messageName

        public java.lang.String messageName()
        Description copied from interface: Schema
        Returns the simple name of the message tied to this schema. Allows custom schemas to provide a custom name other than typeClass().getSimpleName();
        Specified by:
        messageName in interface Schema<java.lang.Object>

      • newMessage

        public java.lang.Object newMessage()

        Throws:
        java.io.IOException

      • writeTo
