### Method Summary

All Methods Instance Methods Abstract Methods
`MessageLite` `getDefaultInstanceForType()` Get an instance of the type with no fields set.
`boolean` `isInitialized()` Returns true if all required fields in the message and all embedded messages are set, false otherwise.

### Method Detail

#### getDefaultInstanceForType

    MessageLite getDefaultInstanceForType()

Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the `getDefaultInstance()` method of generated message classes in that this method is an abstract method of the `MessageLite` interface whereas `getDefaultInstance()` is a static method of a specific class. They return the same thing.

#### isInitialized

    boolean isInitialized()

Returns true if all required fields in the message and all embedded messages are set, false otherwise.
