```
public abstract class AbstractMessage
extends AbstractMessageLite
implements Message
```

Modifier and Type	Method and Description
`boolean`	`equals(Object other)` Compares the specified object with this message for equality.
`List<String>`	`findInitializationErrors()` Returns a list of field paths (e.g.
`String`	`getInitializationErrorString()` Returns a comma-delimited list of required fields which are not set in this message object.
`Descriptors.FieldDescriptor`	`getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)` TODO(jieluo): Clear it when all subclasses have implemented this method.
`int`	`getSerializedSize()` Get the number of bytes required to encode this message.
`int`	`hashCode()` Returns the hash code value for this message.
`protected static int`	`hashFields(int hash, Map<Descriptors.FieldDescriptor,Object> map)` Get a hash code for given fields and values, using the given seed.
`boolean`	`hasOneof(Descriptors.OneofDescriptor oneof)` TODO(jieluo): Clear it when all subclasses have implemented this method.
`boolean`	`isInitialized()` Returns true if all required fields in the message and all embedded messages are set, false otherwise.
`String`	`toString()` Converts the message to a string in protocol buffer text format.
`void`	`writeTo(CodedOutputStream output)` Serializes the message and writes it to `output`.

```
public AbstractMessage()
```
- Method Detail
  - isInitialized
```
public boolean isInitialized()
```
    Description copied from interface: MessageLiteOrBuilder
    
    Returns true if all required fields in the message and all embedded messages are set, false otherwise.
    See also: MessageOrBuilder.getInitializationErrorString()
  - findInitializationErrors
```
public List<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.
  - getInitializationErrorString
```
public 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.
  - hasOneof
```
public boolean hasOneof(Descriptors.OneofDescriptor oneof)
```
    TODO(jieluo): Clear it when all subclasses have implemented this method.
  - getOneofFieldDescriptor
```
public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
```
    TODO(jieluo): Clear it when all subclasses have implemented this method.
  - toString
```
public final String toString()
```
    Description copied from interface: Message
    
    Converts the message to a string in protocol buffer text format. This is just a trivial wrapper around TextFormat.printToString(MessageOrBuilder).
  - writeTo
```
public void writeTo(CodedOutputStream output)
             throws IOException
```
    Description copied from interface: MessageLite
    
    Serializes the message and writes it to output. This does not flush or close the stream.
    
    Specified by:
    
    writeTo in interface MessageLite
    
    Throws:
    
    IOException
  - getSerializedSize
```
public int getSerializedSize()
```
    Description copied from interface: MessageLite
    
    Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.
  - equals
```
public boolean equals(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 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 Object
    
    Returns:
    
    the hash code value for this message
    
    See Also:
    
    Map.hashCode()
  - hashFields
```
protected static int hashFields(int hash,
                                Map<Descriptors.FieldDescriptor,Object> map)
```
    Get a hash code for given fields and values, using the given seed.
