Parser

All Known Implementing Classes:

AbstractParser
```
public interface Parser
```
Abstract interface for parsing Protocol Messages.
The implementation should be stateless and thread-safe.
All methods may throw InvalidProtocolBufferException. In the event of invalid data, like an encoding error, the cause of the thrown exception will be null. However, if an I/O problem occurs, an exception is thrown with an IOException cause.

  - parseFrom
```
MessageType parseFrom(CodedInputStream input)
               throws InvalidProtocolBufferException
```
    Parses a message of MessageType from the input.
    Note: The caller should call CodedInputStream.checkLastTagWas(int) after calling this to verify that the last tag seen was the appropriate end-group tag, or zero for EOF.
    
    Throws:
    
    InvalidProtocolBufferException

  - parseFrom
```
MessageType parseFrom(java.io.InputStream input)
               throws InvalidProtocolBufferException
```
    Parse a message of MessageType from input. This is just a small wrapper around 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 parseDelimitedFrom(InputStream) to read it.
    Despite usually reading the entire input, this does not close the stream.
    
    Throws:
    
    InvalidProtocolBufferException
  - parseFrom
```
MessageType parseFrom(java.io.InputStream input,
                      ExtensionRegistryLite extensionRegistry)
               throws InvalidProtocolBufferException
```
    Parses a message of MessageType from input. This is just a small wrapper around parseFrom(CodedInputStream, ExtensionRegistryLite).
    
    Throws:
    
    InvalidProtocolBufferException
  - parsePartialFrom
```
MessageType parsePartialFrom(java.io.InputStream input)
                      throws InvalidProtocolBufferException
```
    Like parseFrom(InputStream), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned.
    
    Throws:
    
    InvalidProtocolBufferException
  - parsePartialFrom
```
MessageType parsePartialFrom(java.io.InputStream input,
                             ExtensionRegistryLite extensionRegistry)
                      throws InvalidProtocolBufferException
```
    Like parseFrom(InputStream, ExtensionRegistryLite), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned.
    
    Throws:
    
    InvalidProtocolBufferException
  - parseDelimitedFrom
```
MessageType parseDelimitedFrom(java.io.InputStream input)
                        throws InvalidProtocolBufferException
```
    Like parseFrom(InputStream), but does not read until 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.
    
    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
  - parseDelimitedFrom
```
MessageType parseDelimitedFrom(java.io.InputStream input,
                               ExtensionRegistryLite extensionRegistry)

    Like parseDelimitedFrom(InputStream) but supporting extensions.
    
    Throws:

  - parsePartialDelimitedFrom
```
MessageType parsePartialDelimitedFrom(java.io.InputStream input)
                               throws InvalidProtocolBufferException
```
    Like parseDelimitedFrom(InputStream), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned.
