Class UnknownFieldSet.Builder

java.lang.Object
  extended by com.google.protobuf.UnknownFieldSet.Builder
All Implemented Interfaces:
MessageLite.Builder, MessageLiteOrBuilder, Cloneable
Enclosing class:
UnknownFieldSet

public static final class UnknownFieldSet.Builder
extends Object
implements MessageLite.Builder

Builder for UnknownFieldSets.

Note that this class maintains UnknownFieldSet.Field.Builders for all fields in the set. Thus, adding one element to an existing UnknownFieldSet.Field does not require making a copy. This is important for efficient parsing of unknown repeated fields. However, it implies that UnknownFieldSet.Fields cannot be constructed independently, nor can two UnknownFieldSets share the same Field object.

Use UnknownFieldSet.newBuilder() to construct a Builder.

Method Detail

build

public UnknownFieldSet build()
Build the UnknownFieldSet and return it.

Once build() has been called, the Builder will no longer be usable. Calling any method after build() will result in undefined behavior and can cause a NullPointerException to be thrown.

Specified by:
build in interface MessageLite.Builder

buildPartial

public UnknownFieldSet buildPartial()
Description copied from interface: MessageLite.Builder
Like MessageLite.Builder.build(), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned. Subsequent changes to the Builder will not affect the returned message.

Specified by:
buildPartial in interface MessageLite.Builder

clone

public UnknownFieldSet.Builder clone()
Description copied from interface: MessageLite.Builder
Clones the Builder.

Specified by:
clone in interface MessageLite.Builder
Overrides:
clone in class Object
See Also:
Object.clone()

getDefaultInstanceForType

public UnknownFieldSet getDefaultInstanceForType()
Description copied from interface: MessageLiteOrBuilder
Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.

Specified by:
getDefaultInstanceForType in interface MessageLiteOrBuilder

clear

public UnknownFieldSet.Builder clear()
Reset the builder to an empty set.

Specified by:
clear in interface MessageLite.Builder

mergeFrom

public UnknownFieldSet.Builder mergeFrom(UnknownFieldSet other)
Merge the fields from other into this set. If a field number exists in both sets, other's values for that field will be appended to the values in this set.


mergeField

public UnknownFieldSet.Builder mergeField(int number,
                                          UnknownFieldSet.Field field)
Add a field to the UnknownFieldSet. If a field with the same number already exists, the two are merged.


mergeVarintField

public UnknownFieldSet.Builder mergeVarintField(int number,
                                                int value)
Convenience method for merging a new field containing a single varint value. This is used in particular when an unknown enum value is encountered.


hasField

public boolean hasField(int number)
Check if the given field number is present in the set.


addField

public UnknownFieldSet.Builder addField(int number,
                                        UnknownFieldSet.Field field)
Add a field to the UnknownFieldSet. If a field with the same number already exists, it is removed.


asMap

public Map<Integer,UnknownFieldSet.Field> asMap()
Get all present Fields as an immutable Map. If more fields are added, the changes may or may not be reflected in this map.


mergeFrom

public UnknownFieldSet.Builder mergeFrom(CodedInputStream input)
                                  throws IOException
Parse an entire message from input and merge its fields into this set.

Specified by:
mergeFrom in interface MessageLite.Builder
Throws:
IOException

mergeFieldFrom

public boolean mergeFieldFrom(int tag,
                              CodedInputStream input)
                       throws IOException
Parse a single field from input and merge it into this set.

Parameters:
tag - The field's tag number, which was already parsed.
Returns:
false if the tag is an end group tag.
Throws:
IOException

mergeFrom

public UnknownFieldSet.Builder mergeFrom(ByteString data)
                                  throws InvalidProtocolBufferException
Parse data as an UnknownFieldSet and merge it with the set being built. This is just a small wrapper around mergeFrom(CodedInputStream).

Specified by:
mergeFrom in interface MessageLite.Builder
Returns:
this
Throws:
InvalidProtocolBufferException

mergeFrom

public UnknownFieldSet.Builder mergeFrom(byte[] data)
                                  throws InvalidProtocolBufferException
Parse data as an UnknownFieldSet and merge it with the set being built. This is just a small wrapper around mergeFrom(CodedInputStream).

mergeFrom

public UnknownFieldSet.Builder mergeFrom(InputStream input)
                                  throws IOException
Parse an UnknownFieldSet from input and merge it with the set being built. This is just a small wrapper around mergeFrom(CodedInputStream).

mergeDelimitedFrom

public boolean mergeDelimitedFrom(InputStream input)
                           throws IOException
Description copied from interface: MessageLite.Builder
Like MessageLite.Builder.mergeFrom(InputStream), but does not read until EOF. Instead, the size of the message (encoded as a varint) is read first, then the message data. Use MessageLite.writeDelimitedTo(OutputStream) to write messages in this format.

Specified by:
mergeDelimitedFrom in interface MessageLite.Builder
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:
IOException

mergeDelimitedFrom

public boolean mergeDelimitedFrom(InputStream input,
                                  ExtensionRegistryLite extensionRegistry)
                           throws IOException
Description copied from interface: MessageLite.Builder
Like MessageLite.Builder.mergeDelimitedFrom(InputStream) but supporting extensions.

Specified by:
mergeDelimitedFrom in interface MessageLite.Builder
Throws:
IOException

mergeFrom

public UnknownFieldSet.Builder mergeFrom(CodedInputStream input,

                                  throws IOException
Description copied from interface: MessageLite.Builder
Like MessageLite.Builder.mergeFrom(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:
mergeFrom in interface MessageLite.Builder
Throws:
IOException
