Method Detail

isEmpty

public boolean isEmpty()

Description copied from interface: UnknownFieldSet

Checks if there are any fields in this set.

Specified by:

readAllFields

public void readAllFields(RawProtoStreamReader input)
                   throws IOException

Description copied from interface: UnknownFieldSet

Parse an entire message from input and merge its fields into this set.

Specified by:

readAllFields in interface UnknownFieldSet

Throws:

IOException

readSingleField

public boolean readSingleField(int tag,
                               RawProtoStreamReader input)
                        throws IOException

Description copied from interface: UnknownFieldSet

Parse a single field from input and merge it into this set.

Specified by:

readSingleField in interface UnknownFieldSet

Parameters:

tag - The field's tag number, which was already parsed (tag contains both field id and wire type).

Returns:

false if the tag is an end group tag.

Throws:

IOException

putVarintField

public void putVarintField(int tag,
                           int value)

Description copied from interface: UnknownFieldSet

Convenience method for merging a new field containing a single varint value. This is used in particular when an unknown enum value is encountered.

Specified by:

putVarintField in interface UnknownFieldSet

Parameters:

tag - the field tag (containing both field id and wire type).

writeTo

public void writeTo(RawProtoStreamWriter output)
             throws IOException

Description copied from interface: UnknownFieldSet

Writes all fields from this set to the output stream.

Specified by:

writeTo in interface UnknownFieldSet

Throws:

IOException

consumeTag

public <A> A consumeTag(int tag)

Description copied from interface: UnknownFieldSet

Reads and removes a field value from the set. The field is specified as a tag value composed of the numeric id of the field and the wire type. It's possible that the tag has repeated values; in that case the first one is returned.
