Class NBTypeConverter

java.lang.Object

io.nosqlbench.nb.api.config.standard.NBTypeConverter

public class NBTypeConverter
extends Object

Shenanigans in the java type system, particularly those around boxing, generics, type-erasure and primitive conversions have brought us here in our attempt to simplify things. In the future, when Java has fewer special cases in the type system, this class can be removed. General purpose strategies for conversion can be injected into the do_convert(Object, Class) and canConvert(Object, Class) methods.
