Member Function Documentation

BitSet SetUtil::bitSetAndNot (  BitSet   originalSet, BitSet   notSet )  [inline, static, private]

Clear elements of a bit set in terms of a ruler bit set. Returns: result bit set. Parameters: orignalSet   a bit set need to be cleared by a ruler. notSet   ruler bit set. Definition at line 54 of file SetUtil.java.

Set SetUtil::bitSetToStmtSet (  BitSet   bitSet, StmtList   stmtList )  [inline, static]

Transform a bit set of statements into a set of Stmt. Returns: a set of Stmt which is corresponding to the bitSet. Parameters: bitSet   a bit set of statements indexed with stmtList. stmtList   statement list. Definition at line 69 of file SetUtil.java.

boolean SetUtil::emptyBitSet (  BitSet   bs )  [inline, static]

See if a bit set is empty Returns: true if it is empty; false otherwise. Parameters: bs   query bit set. Definition at line 84 of file SetUtil.java.

boolean SetUtil::emptyBitSetWithLength (  BitSet   bs, int   length )  [inline, static]

See if a bit set is empty Returns: true if it is empty; false otherwise. Parameters: bs   query bit set. Definition at line 96 of file SetUtil.java.

void SetUtil::initializeBitSetToAllFalse (  BitSet   bs )  [inline, static]

Insert the method's description here. Creation date: (00-12-6 11:01:22) Parameters: bs   java.util.BitSet Definition at line 107 of file SetUtil.java.

void SetUtil::initializeBitSetToAllTrue (  BitSet   bs )  [inline, static]

Insert the method's description here. Creation date: (00-12-6 11:01:22) Parameters: bs   java.util.BitSet Definition at line 116 of file SetUtil.java.

int SetUtil::logicalSizeOfBitSet (  BitSet   bs )  [inline, static, private]

Get logical size of a bit set. Logical size means how many element in a bit set is set to true. Returns: logical size of the bit set. Parameters: bs   query bit set. Definition at line 127 of file SetUtil.java.

Set SetUtil::setIntersection (  Set   set1, Set   set2 )  [inline, static]
