com.google.protobuf.AbstractParser<MessageType>

All Implemented Interfaces:

Parser<MessageType>

Direct Known Subclasses:

UnknownFieldSet.Parser

public abstract class AbstractParser<MessageType extends MessageLite>
extends java.lang.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)

Method Detail

parsePartialFrom

public MessageType parsePartialFrom(CodedInputStream input)
                                                 throws InvalidProtocolBufferException

Description copied from interface: Parser

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

Specified by:

parsePartialFrom in interface Parser<MessageType extends MessageLite>

Throws:

InvalidProtocolBufferException

parseFrom

public MessageType parseFrom(CodedInputStream input,
                    ExtensionRegistryLite extensionRegistry)
                                          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

parseFrom

public MessageType parseFrom(CodedInputStream input)
                                          throws InvalidProtocolBufferException

Description copied from interface: Parser

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.

Specified by:

parseFrom in interface Parser<MessageType extends MessageLite>

Throws:

InvalidProtocolBufferException

parseFrom

public MessageType parseFrom(java.io.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.

Specified by:

parseFrom in interface Parser<MessageType extends MessageLite>

Throws:

InvalidProtocolBufferException

parsePartialDelimitedFrom

public MessageType parsePartialDelimitedFrom(java.io.InputStream input,
                                    ExtensionRegistryLite extensionRegistry)

                                                   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:

True if successful, or false 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
