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)
