## Class MapEntryLite<K,V>

- java.lang.Object
- - com.google.protobuf.MapEntryLite<K,V>

-     public class MapEntryLite<K,V>
      extends java.lang.Object

  Implements the lite version of map entry messages. This class serves as an utility class to help do serialization/parsing of map entries. It's used in generated code and also in the full version MapEntry message. Protobuf internal. Users shouldn't use.

- - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `int` | `computeMessageSize(int fieldNumber, K key, V value)` Computes the message size for the provided key and value as though they were wrapped by a `MapEntryLite`.
    `K` | `getKey()`
    `V` | `getValue()`
    `static <K,V> MapEntryLite<K,V>` | `newDefaultInstance(WireFormat.FieldType keyType, K defaultKey, WireFormat.FieldType valueType, V defaultValue)` Creates a default MapEntryLite message instance.
    `java.util.Map.Entry<K,V>` | `parseEntry(ByteString bytes, ExtensionRegistryLite extensionRegistry)` Parses an entry off of the input as a `Map.Entry`.
    `void` | `parseInto(MapFieldLite<K,V> map, CodedInputStream input, ExtensionRegistryLite extensionRegistry)` Parses an entry off of the input into the map.
    `void` | `serializeTo(CodedOutputStream output, int fieldNumber, K key, V value)` Serializes the provided key and value as though they were wrapped by a `MapEntryLite` to the output stream.

- - ### Method Detail

    - #### getKey

          public K getKey()

    - #### getValue

          public V getValue()

    - #### newDefaultInstance

          public static <K,V> MapEntryLite<K,V> newDefaultInstance(WireFormat.FieldType keyType,
                                                   K defaultKey,
                                                   WireFormat.FieldType valueType,
                                                   V defaultValue)

      Creates a default MapEntryLite message instance. This method is used by generated code to create the default instance for a map entry message. The created default instance should be used to create new map entry messages of the same type. For each map entry message, only one default instance should be created.

    - #### serializeTo

          public void serializeTo(CodedOutputStream output,
                         int fieldNumber,
                         K key,
                         V value)
                           throws java.io.IOException

      Serializes the provided key and value as though they were wrapped by a `MapEntryLite` to the output stream. This helper method avoids allocation of a `MapEntryLite` built with a key and value and is called from generated code directly.
      Throws:
        `java.io.IOException`

    - #### computeMessageSize

          public int computeMessageSize(int fieldNumber,
                               K key,
                               V value)

      Computes the message size for the provided key and value as though they were wrapped by a `MapEntryLite`. This helper method avoids allocation of a `MapEntryLite` built with a key and value and is called from generated code directly.

    - #### parseEntry

          public java.util.Map.Entry<K,V> parseEntry(ByteString bytes,
                                            ExtensionRegistryLite extensionRegistry)
                                              throws java.io.IOException

      Parses an entry off of the input as a `Map.Entry`. This helper requires an allocation so using `parseInto(com.google.protobuf.MapFieldLite<K, V>, com.google.protobuf.CodedInputStream, com.google.protobuf.ExtensionRegistryLite)` is preferred if possible.
      Throws:
        `java.io.IOException`

    - #### parseInto

          public void parseInto(MapFieldLite<K,V> map,
                       CodedInputStream input,
                       ExtensionRegistryLite extensionRegistry)
                         throws java.io.IOException

      Parses an entry off of the input into the map. This helper avoids allocaton of a `MapEntryLite` by parsing directly into the provided `MapFieldLite`.
      Throws:
        `java.io.IOException`
