Method Detail
-
setMask
public void setMask(int mask)
Set the mask for this bit array. The upper 8 bits of this mask indicate the DOM in which the nodes in this array belong.
-
getMask
public int getMask()
See setMask()
-
size
public final int size()
Returns the size of this bit array (in bits).
-
getBit
public final boolean getBit(int bit)
Returns true if the given bit is set
-
getNextBit
public final int getNextBit(int startBit)
Returns the next set bit from a given position
-
getBitNumber
public final int getBitNumber(int pos)
-
data
public final int[] data()
Returns the integer array in which the bit array is contained
-
setBit
public final void setBit(int bit)
Sets a given bit
-
merge
public final BitArray merge(BitArray other)
Merge two bit arrays. This currently only works for nodes from a single DOM (because there is only one _mask per array).
-
resize
public final void resize(int newSize)
Resizes the bit array - try to avoid using this method!!!
-
cloneArray
public BitArray cloneArray()
