Method Detail

addRule

public static void addRule(int[][] type,
                           int mode,
                           int rowtype,
                           ArrayList<Integer> columns,
                           ArrayList<ArrayList<Object>> frame)

Calculates a rule and adds it to the frame (if not empty).

Parameters:

type - rule type and options, use one of topRule, midRule, or bottomRule

mode - the grid mode (from addGrid)

rowtype - the row type (determined by addGrid)

columns - the columns of the text (determined by addGrid)

frame - internal frame to add the rendered rule to

addContentRow

public static void addContentRow(String[][] ar,
                                 int mode,
                                 int rowtype,
                                 ArrayList<ArrayList<Object>> frame)

Calculates a content row and adds it to the frame (if not empty).

Parameters:

ar - the content

mode - the grid mode (from addGrid)

rowtype - the row type (determined by addGrid)

frame - internal frame to add the rendered row to

adjustBorder

public static int adjustBorder(int postype,
                               int v,
                               int h,
                               int mode,
                               ArrayList<ArrayList<Object>> frame)

Adjusts borders, testing if a particular border character is connected uo, down, left, and right in the grid.

Parameters:

postype - the border character as position/type

v - position of the character vertically in the frame

h - position of the character horizontally in the frame

mode - mode the grid mode (from addGrid)

frame - the internal frame to find connected characters

Returns:

the adjusted character to be used finally to find the actual border character

hasType

public static boolean hasType(int postype)

Tests if the given position/type has a type, that is an up, down, left, or right.

Parameters:

postype - position/type to test

Returns:

true if the given position/type already has a type, false otherwise

convertBorders

public static int convertBorders(int postype,
                                 int v,
                                 int h,
                                 int vsize,
                                 int hsize,
                                 int mode)

Removes left/right connections if the given mode requires it and the position/type is a border.

Parameters:

postype - the type position to test

v - vertical position of position/type

h - horizontal position of position/type

vsize - max vertical index

hsize - max horizontal index

mode - the mode to test against

Returns:

original position/type if no border conversion was needed, converted position/type otherwise

convertConnectors

public static int convertConnectors(int postype,
                                    int v,
                                    int h,
                                    int vsize,
                                    int hsize,
                                    int mode)

Removes top/down connections if the given mode requires and the position/type is a connector. The method will process top/bottom/mid separately

Parameters:

postype - the type position to test

v - vertical position of position/type

h - horizontal position of position/type

vsize - max vertical index

hsize - max horizontal index

mode - the mode to test against

Returns:

original position/type if no connector conversion was needed, converted position/type otherwise
