Interface Parser<MessageType>

All Known Implementing Classes:

AbstractParser, GeneratedMessageLite.DefaultInstanceBasedParser, UnknownFieldSet.Parser

public interface Parser<MessageType>

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.

Method Detail

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(CodedInputStream input,
                    ExtensionRegistryLite extensionRegistry)
                      throws InvalidProtocolBufferException

Like 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.

Throws:

InvalidProtocolBufferException

parsePartialFrom

MessageType parsePartialFrom(CodedInputStream input)
                             throws InvalidProtocolBufferException

Like parseFrom(CodedInputStream), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned.

Throws:

InvalidProtocolBufferException

parsePartialFrom

                           ExtensionRegistryLite extensionRegistry)
                             throws InvalidProtocolBufferException

parseFrom

MessageType parseFrom(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(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(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(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(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

Throws:

InvalidProtocolBufferException

parsePartialDelimitedFrom
