Parses given string and returns true if string is "on" or "true" false otherwise. Tests are case insensitive.

Parameters:

arg - string to parse.

Returns:

true if string is "on" or "true" false otherwise.

Since:

1.0

parseColor

public static int parseColor(String arg)

Parses string as hexadecimal integer representation and returns color as integer or -1 if string is null or can't be parsed.

Parameters:

arg - string to be parsed.

Returns:

color as integer or -1 if string is null or can't be parsed

Since:

parseFontFace

public static int parseFontFace(String face)

Parses string and returns fonts face as integer. String must be of form

 PROPRTIONAL | MONOSPACE | SYSTEM
 

to be parsed. Test are case insensitive. Spaces are not allowed.

Parameters:

face - string to be parsed.

Returns:

font's face as integer.

Throws:

NullPointerException - if face is null.

Since:

1.0

parseFontStyle

public static int parseFontStyle(String style)

Parses string and returns fonts style as integer. String must be of form

                                                  (PLAIN|BOLD|ITALIC|UNDERLINED)(;(PLAIN|BOLD|ITALIC|UNDERLINED))*
 

to be parsed. Test are case insensitive. Spaces are not allowed.

Parameters:

style - string to be parsed.

Returns:

font's style as integer.

Throws:

NullPointerException - if style is null.

IllegalArgumentException - if style is not of valid form.

Since:

1.0

parseFontSize

public static int parseFontSize(String size)

Parses string and returns fonts size as integer. String must be of form

 LARGE | MEDIUM | SMALL
 

to be parsed. Test are case insensitive. Spaces are not allowed.

Parameters:

size - string to be parsed.

Returns:

font's size as integer.

Throws:

parseFont

public static Font parseFont(String arg)

Parses string and returns font. String must be of form

                                            <Face>,<Style>,<Size>
                                              Face = PROPRTIONAL|MONOSPACE|SYSTEM
                                              Style = (PLAIN|BOLD|ITALIC|UNDERLINED)(;(PLAIN|BOLD|ITALIC|UNDERLINED))*
                                              Size = LARGE|MEDIUM|SMALL
 

to be parsed. Test are case insensitive. Spaces are not allowed.

Parameters:

arg - string to be parsed.

Returns:

font or null if string is null or not of valid form.

Since:

isTestSeparator

public static boolean isTestSeparator(char c)

Checks if the given character is separator.

Parameters:

c - character to be tested.

Returns:

true if character is separator, false otherwise.

Since:

1.0

parseTimeInterval

public static long parseTimeInterval(String timeInterval)

Parses given string. Returns the time interval as number of milliseconds or -1 if parse error occurs. String must be of the form:

<DoubleLiteral>[<UnitSuffix>]

DoubleLiteral is double number string representation as specified by Double.valueOf(String).

UnitSuffix is an optional specification of unit of time. It can be one of the following

• h - for hours;
• m - for minutes;
• s - for seconds;
• ms - for milliseconds.

If omitted milliseconds are implied. UnitSuffix is case insensitive (ms, MS, Ms, mS mean the same).

Parameters:

timeInterval - string representing time interval.

Returns:

the time interval in milliseconds or -1 if string is not parsable.
