- ghidra.graph.viewer.layout.GridLocationMap<V,E>
-
- Type Parameters:
V
- the vertex typeE
- the edge type
public class GridLocationMap<V,E> extends java.lang.Object
An object that maps vertices to rows and columns and edges to their articulation points. This class is essentially a container that allows layout algorithms to store results, which can later be turned into layout positioning points. The integer point values in this class are row, column grid values, starting at 0,0.Note: the Point2D values for the edge articulations use x,y values that are row and column index values, the same values as calling
row(V)
andcol(V)
.After building the grid using this class, clients can call
rows()
to get high-order object that represent rows.

rows
public java.util.List<Row<V>> rows()
Returns the rows in this grid, sorted by index (index can be negative)- Returns:
- the rows in this grid
-
centerRows
public void centerRows()
Updates each row within the grid such that it's x values are set to center the row in the grid. Each row will be updated so that all its columns start at zero. After that, each column will be centered in the grid.
