Writes the layout for a NodeLayout.

valueOf

public static java.lang.String valueOf(java.awt.Color c)

Gets the standard string representation of a java color.

parseText

public static java.lang.String parseText(org.w3c.dom.Node text)

Concatenates the first adjacent text node children of text.

Parameters:

text - The parent node whose text content is evaluated.

Returns:

The concatenated content of the first adjacent text node children of text.

parseNodeLayout

public static void parseNodeLayout(org.w3c.dom.Node root,
                                   NodeLayout nl)

Configure the specified node layout from the data in the given XML node.

Parameters:

root - The layout data

nl - The NodeLayout to configure.

parsePath

public static void parsePath(org.w3c.dom.Node root,
                             EdgeLayout el)

Configure the specified edge layout from the data in the given XML node.

Parameters:

root - The layout data

el - The edge layout to configure.

parseColor

public static java.awt.Color parseColor(java.lang.String colorString)

Decodes a color string produced by valueOf(java.awt.Color).

Parameters:

colorString - the color string

Returns:

an opaque color if the color string is of the form #RRGGBB and a transparent color if the input string is of the form #RRGGBBAA, where AA denotes the alpha component of the color.

parseColor

public static java.awt.Color parseColor(java.lang.String colorString,
                                        boolean isRGBA)

Decodes color strings in hexadecimal RGB, RGBA and ARGB formats. For RGB, the string format is assumed to be #RRGGBB. For RGBA, the string format is assumed to be #RRGGBBAA. For ARGB, the string format is assumed to be #AARRGGBB.

Parameters:

colorString - the color string.

isRGBA - if true, input with four color channels is assumed to be in RGBA format; otherwise it is assumed to be in ARGB format.
