Method Detail

hasExtensions

abstract boolean hasExtensions(MessageLite prototype)

Returns true for messages that support extensions.

getExtensions

abstract FieldSet<T> getExtensions(java.lang.Object message)

Returns the extension FieldSet for the message instance.

setExtensions

abstract void setExtensions(java.lang.Object message,
                            FieldSet<T> extensions)

Replaces the extension FieldSet for the message instance.

getMutableExtensions

abstract FieldSet<T> getMutableExtensions(java.lang.Object message)

Returns the extension FieldSet and ensures it's mutable.

makeImmutable

abstract void makeImmutable(java.lang.Object message)

Marks the extension FieldSet as immutable.

parseExtension

abstract <UT,UB> UB parseExtension(java.lang.Object containerMessage,
                                         Reader reader,
                                         java.lang.Object extension,
                                         ExtensionRegistryLite extensionRegistry,
                                         FieldSet<T> extensions,
                                         UB unknownFields,
                                         UnknownFieldSchema<UT,UB> unknownFieldSchema)
                                  throws java.io.IOException

Parses an extension. Returns the passed-in unknownFields parameter if no unknown enum value is found or a modified unknownFields (a new instance if the passed-in unknownFields is null) containing unknown enum values found while parsing.

Type Parameters:

UT - The type used to store unknown fields. It's either UnknownFieldSet in full runtime or UnknownFieldSetLite in lite runtime.

Throws:

java.io.IOException

extensionNumber

abstract int extensionNumber(java.util.Map.Entry<?,?> extension)

Gets the field number of an extension entry.

serializeExtension

abstract void serializeExtension(Writer writer,
                                 java.util.Map.Entry<?,?> extension)
                          throws java.io.IOException

Serializes one extension entry.

Throws:

java.io.IOException

findExtensionByNumber

abstract java.lang.Object findExtensionByNumber(ExtensionRegistryLite extensionRegistry,
                                                MessageLite defaultInstance,
                                                int number)

Finds an extension by field number.

parseLengthPrefixedMessageSetItem

abstract void parseLengthPrefixedMessageSetItem(Reader reader,
                                                java.lang.Object extension,
                                                ExtensionRegistryLite extensionRegistry,
                                                FieldSet<T> extensions)
                                         throws java.io.IOException

Parses a length-prefixed MessageSet item from the reader.

Throws:

java.io.IOException

parseMessageSetItem

abstract void parseMessageSetItem(ByteString data,
                                  java.lang.Object extension,
                                  ExtensionRegistryLite extensionRegistry,
                                  FieldSet<T> extensions)
                           throws java.io.IOException

Parses the entire content of a ByteString as one MessageSet item. Unlike parseLengthPrefixedMessageSetItem(com.google.protobuf.Reader, java.lang.Object, com.google.protobuf.ExtensionRegistryLite, com.google.protobuf.FieldSet<T>), there isn't a length-prefix.

Throws:

java.io.IOException
