Method Details

getBitsPerFlag

public int getBitsPerFlag()

Gets the number of bits used to represent the edge flag for each vertex. But only the least significant 2 bits in each flag value shall be used. The valid flag values are 0, 1, 2 or 3.

Returns:

the number of bits. Can be 2, 4 or 8

setBitsPerFlag

public final void setBitsPerFlag(int bitsPerFlag)

Sets the number of bits used to represent the edge flag for each vertex. But only the least significant 2 bits in each flag value shall be used. The valid flag values are 0, 1, 2 or 3.

Parameters:

bitsPerFlag - the number of bits to be set. Shall be 2, 4 or 8
