Method Detail

render

public GGraph render(FAState state)

This method is the entry point of this class. It computes the size and position of each node and link. The position are literal and are actually evaluated later, when displaying the syntax diagram.

renderPosition

public void renderPosition(FAState state)

recursiveRenderPositionNode

public void recursiveRenderPositionNode(FAState state,
                               FAState endState,
                               GPoint basePoint)

recursiveRenderPositionAlternative

public FAState recursiveRenderPositionAlternative(FAState state,
                                         GPoint basePoint)

renderSize

public GDimension renderSize(FAState state)

recursiveRenderSizeSingle

public GDimension recursiveRenderSizeSingle(FAState state,
                                   FAState endState)

recursiveRenderSizeAlternative

public GDimension recursiveRenderSizeAlternative(FAState state)

createNode

public GNode createNode(FAState state)

getNode

public GNode getNode(FAState state)

alternativeEndState

public FAState alternativeEndState(FAState alt)
