alloc() public method

This is to implement memory allocation in the array. Like malloc().
public alloc ( int size ) : int
size int
return int

Example #1
0
 public HyphenationTree()
 {
     stoplist = new Dictionary <>(23);    // usually a small table
     classmap = new TernaryTree();
     vspace   = new ByteVector();
     vspace.alloc(1);     // this reserves index 0, which we don't use
 }
Example #2
0

		classmap = new TernaryTree();
		vspace = new ByteVector();
		vspace.alloc(1); // this reserves index 0, which we don't use
