Field Detail

nodes

private Vector nodes

Keeps all nodes of this row

rowNumber

private int rowNumber

The row number of this row

Constructor Detail

ClassdiagramLayouter.NodeRow

public ClassdiagramLayouter.NodeRow(int aRowNumber)

Construct an empty NodeRow with the given row number

Method Detail

addNode

public void addNode(ClassdiagramNode node)

Add a node to this NodeRow.

Parameters:

node - The node to be added

doSplit

public ClassdiagramLayouter.NodeRow doSplit(int maxWidth,
                                            int gap)

Splittable are packages and stanalone-nodes. A split is performed, if the maximum width is reached or when a type change occurs (from package to not-package, from standalone to not-standalone).

• packages
• After standalone

Split this row into two, if

• at least one standalone node is availabe
• and the given maximum row width is exceeded
• or a non-standalone element is detected.

Return the new NodeRow or null if this row is not split.

Parameters:

maxWidth - The maximum allowed row width

gap - The horizontal gab between two nodes

Returns:

NodeRow

getNodes

public Vector getNodes()

Returns:

Returns the nodes.

getRowNumber

public int getRowNumber()

Returns:

Returns the rowNumber.

getSortedIterator

public Iterator getSortedIterator()

Get an Iterator for the nodes of this row, sorted by their natural order

Returns:

Iterator for sorted nodes

getWidth

public int getWidth(int gap)

Get the width for this row using the given horizontal gap between nodes.

Parameters:

gap - The horizontal gap between nodes

Returns:

The width of this row

setRowNumber

public void setRowNumber(int rowNum)

Set the row number of this row

Parameters:

rowNum - The rowNumber to set.

adjustRowNodes

private void adjustRowNodes()

Adjust the properties for all nodes in this row: rank, column, offset for edges
