Class NumberConverters

java.lang.Object

org.bbottema.javareflection.valueconverter.converters.NumberConverters

public class NumberConverters
extends Object

Generates converters for all numbers to all other numbers, by virtue of Number's own interface that forces all subclasses to implement basic conversions to common other Number classes.

Attempts to convert a Number to the target datatype.

NOTE: precision may be lost when converting from a wide number to a narrower number (say float to integer). These conversions are done by simply calling Number.intValue() and Number.floatValue() etc.

Conversions are as follows:

1. String: value.toString()
2. Integer: value.intValue()
3. Boolean: value.intValue() > 0
4. Float: value.floatValue()
5. Double: value.doubleValue()
6. Long: value.longValue()
7. Byte: value.byteValue()
8. Short: value.shortValue()
9. Character: Character.forDigit(value, 10) (Character.forDigit(int, int))
