Method Summary
`protected static boolean`	`convertToBoolean(java.lang.Object obj)` Returns true if the value is a Number and not equal to 0, a character equal to 't' or 'T', a boolean true value, or a String "true".
`protected static byte`	`convertToByte(java.lang.Object obj)` Returns Number.byteValue() if possible, 1 for true, 0 for false, or new Byte(toString).byteValue().
`protected static char`	`convertToChar(java.lang.Object obj)` Returns the first character of a Number converted to a String, 't' for a boolean true value, 'f' for a boolean false value, or the first character in obj.toString().
`protected static double`	`convertToDouble(java.lang.Object obj)` Returns Number.doubleValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Double(toString).doubleValue().
`protected static float`	`convertToFloat(java.lang.Object obj)` Returns Number.floatValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Float(toString).floatValue().
`protected static int`	`convertToInt(java.lang.Object obj)` Returns Number.intValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Integer(toString).intValue().
`protected static long`	`convertToLong(java.lang.Object obj)` Returns Number.longValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Long(toString).longValue().
`protected static short`	`convertToShort(java.lang.Object obj)` Returns Number.shortValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Short(toString).shortValue().

Method Detail

convertToInt

protected static int convertToInt(java.lang.Object obj)

Returns Number.intValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Integer(toString).intValue(). It returns 0 if no conversion is successful.

convertToByte

protected static byte convertToByte(java.lang.Object obj)

Returns Number.byteValue() if possible, 1 for true, 0 for false, or new Byte(toString).byteValue(). It returns 0 if no conversion is successful.

convertToLong

protected static long convertToLong(java.lang.Object obj)

Returns Number.longValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Long(toString).longValue(). It returns 0 if no conversion is successful.

convertToShort

protected static short convertToShort(java.lang.Object obj)

Returns Number.shortValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Short(toString).shortValue(). It returns 0 if no conversion is successful.

convertToFloat

protected static float convertToFloat(java.lang.Object obj)

Returns Number.floatValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Float(toString).floatValue(). It returns 0 if no conversion is successful.

convertToDouble

protected static double convertToDouble(java.lang.Object obj)

Returns Number.doubleValue() if possible, 1 for true, 0 for false, the digit if it's a character and a digit, or new Double(toString).doubleValue(). It returns 0 if no conversion is successful.

convertToBoolean

protected static boolean convertToBoolean(java.lang.Object obj)

Returns true if the value is a Number and not equal to 0, a character equal to 't' or 'T', a boolean true value, or a String "true". Otherwise it returns false.

convertToChar

protected static char convertToChar(java.lang.Object obj)

Returns the first character of a Number converted to a String, 't' for a boolean true value, 'f' for a boolean false value, or the first character in obj.toString(). If it throws an exception, it returns '?'.
