Class CompressedCodePointSet

java.lang.Object
com.oracle.truffle.regex.charset.CompressedCodePointSet
public final class CompressedCodePointSet extends Object
Compressed variant of CodePointSet. Stores clusters of small ranges as bit sets, if possible. Every range in this set's sorted list of ranges may be associated to a bit set, which stores the more "fine-grained" ranges inside the larger range. Example: 
 Character set:
 [0x02, 0x04, 0x06, 0x1000, 0x1020-0x1030]

 Resulting compressed code point set:
 - ranges:   [0x02-0x06,          0x1000, 0x1020-0x1030]
 - bit-sets: [[0x02, 0x04, 0x06], null,   null         ]
