AbstractParser

java.lang.Object
- com.google.protobuf.AbstractParser<MessageType>

All Implemented Interfaces:

Parser<MessageType>

Direct Known Subclasses:

GeneratedMessageLite.DefaultInstanceBasedParser
```
public abstract class AbstractParser<MessageType extends MessageLite>
extends Object
implements Parser<MessageType>
```
A partial implementation of the Parser interface which implements as many methods of that interface as possible in terms of other methods. Note: This class implements all the convenience methods in the Parser interface. See Parser for related javadocs. Subclasses need to implement Parser.parsePartialFrom(CodedInputStream, ExtensionRegistryLite)

@Nullable
public MessageType parseDelimitedFrom(InputStream input)
                                         throws InvalidProtocolBufferException
```
    Description copied from interface: Parser
    
    Like Parser.parseFrom(InputStream), but does not read util EOF. Instead, the size of message (encoded as a varint) is read first, then the message data. Use MessageLite.writeDelimitedTo(java.io.OutputStream) to write messages in this format.
    
    Specified by:
    
    parseDelimitedFrom in interface Parser<MessageType extends MessageLite>
    
    Returns:
    
    Parsed message if successful, or null if the stream is at EOF when the method starts. Any other error (including reaching EOF during parsing) will cause an exception to be thrown.
    
    Throws:
    
    InvalidProtocolBufferException

```
    Description copied from interface: Parser
    
    Like Parser.parseFrom(CodedInputStream), but also parses extensions. The extensions that you want to be able to parse must be registered in extensionRegistry. Extensions not in the registry will be treated as unknown fields.
    
    Specified by:
    
    parseFrom in interface Parser<MessageType extends MessageLite>
    
    Throws:
    
    InvalidProtocolBufferException

```
public MessageType parseFrom(InputStream input)
                      throws InvalidProtocolBufferException
```
    Description copied from interface: Parser
    
    Parse a message of MessageType from input. This is just a small wrapper around Parser.parseFrom(CodedInputStream). Note that this method always reads the entire input (unless it throws an exception). If you want it to stop earlier, you will need to wrap your input in some wrapper stream that limits reading. Or, use MessageLite.writeDelimitedTo(java.io.OutputStream) to write your message and Parser.parseDelimitedFrom(InputStream) to read it.
    Despite usually reading the entire input, this does not close the stream.
