Class brsVisitor.BRSDisplayAdapter$RowColIdx

class BRSDisplayAdapter$RowColIdx
extends Object
This class is a "carrier" class that holds the row and column index for a node in a BiTree. The rows are numbered from 0 at the first row. The columns are numbered from 0 from the left. This class is also a factory for the RowColIdx needed for the left and right sub-trees of the present node. This is a private inner class of BRSDisplayAdapter.

Variable Index

o colIdx
The stored column index
o rowIdx

Constructor Index

o RowColIdx (int, int)
Constructor for the class

Method Index

o getColIdx ()
Accessor method for the row index
o getRowIdx ()
Accessor method for the row index
o nextLeft ()
Factory method for the RowColIdx instance needed for the left sub-tree
o nextRight ()
Factory method for the RowColIdx instance needed for the left sub-tree

Variables

o colIdx 
int colIdx
The stored column index.

o rowIdx 
int rowIdx

Constructors

o RowColIdx 
public  RowColIdx(int rowIdx, int colIdx)
Constructor for the class.

Parameters:
rowIdx - The row index
colIdx - The column index

Methods

o getRowIdx 
int getRowIdx()
Accessor method for the row index.

Returns:
o getColIdx 
int getColIdx()
Accessor method for the row index.

Returns:
o nextLeft 
RowColIdx nextLeft()
Factory method for the RowColIdx instance needed for the left sub-tree. The new (row, col) indices are (row+1, 2*col)

Returns:
A new RowColIdx instance
o nextRight 
RowColIdx nextRight()
Factory method for the RowColIdx instance needed for the left sub-tree. The new (row, col) indices are (row+1, 2*col+1)

Returns:
A new RowColIdx instance
