alignComponent
public static void alignComponent(Component parent,
Component child,
String alignment)
convertStringToBoolean
public static Boolean convertStringToBoolean(String s)
convertStringToDouble
public static Double convertStringToDouble(String s)
- Converts a specified string to a floating point value. Returns null if the string cannot be converted.
- Parameters:
s - the string to convert.
- Returns:
- floating point value of the string, or null if the string cannot be converted.
- Throws:
IllegalArgumentException - if the string is null.
convertStringToInteger
public static Integer convertStringToInteger(String s)
- Converts a specified string to an integer value. Returns null if the string cannot be converted.
- Parameters:
s - the string to convert.
- Returns:
- integer value of the string, or null if the string cannot be converted.
- Throws:
IllegalArgumentException - if the string is null.
convertStringToLong
public static Long convertStringToLong(String s)
- Converts a specified string to a long integer value. Returns null if the string cannot be converted.
- Parameters:
s - the string to convert.
- Returns:
- long integer value of the string, or null if the string cannot be converted.
- Throws:
IllegalArgumentException - if the string is null.
decodeColor
public static Color decodeColor(String encodedString)
- Returns the Color described by the String
encodedString. This understands Colors encoded with a call
to encodeColor(java.awt.Color). If encodedString cannot be decoded, this method returns
null.
- Parameters:
encodedString - String to decode.
- Returns:
- Color decoded from the specified
encodedString, or null if the String cannot be decoded.
- Throws:
IllegalArgumentException - If encodedString is null.
doListFileNames
protected static void doListFileNames(File file,
FileFilter filter,
boolean recurse,
boolean exitBranchOnFirstMatch,
Collection<String> names)
doListFileNames
protected static String[] doListFileNames(String filePath,
FileFilter filter,
boolean recurse,
boolean exitBranchOnFirstMatch)
encodeColor
public static String encodeColor(Color color)
- Returns a String encoding of the specified
color. The Color can be restored with a call to decodeColor(String).
- Parameters:
color - Color to encode.
- Returns:
- String encoding of the specified
color.
- Throws:
IllegalArgumentException - If color is null.
listAllFileNames
public static String[] listAllFileNames(String filePath,
FileFilter filter)
listFile
