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         ]
