Class TypeConverter

java.lang.Object

com.flowlogix.util.TypeConverter

public class TypeConverter
extends Object

Converts from any String to any type dynamically, using static valueOf(String input) method of the target type, or other methods with equivalent functionality

Accepts database special values, such as inf, -inf, and nan

Examples:

int one = TypeConverter.valueOf("1", int.class);

TT convertedValue = TypeConverter.valueOf(input, cls);

CheckedValue<TT> checkedValue = TypeConverter.checkAndConvert(input, cls);
if (checkedValue.isValid()) {
    // get and operate on a value in a type-safe way
    TT value = checkedValue.getValue();
}
