JavaToIfxType (informix-jdbc 4.10.12 API)

java.lang.Object
- com.informix.lang.JavaToIfxType

```
public final class JavaToIfxType
extends java.lang.Object
```
This static class handles all the Java to Informix data conversion. A separate method is provided for each conversion. All the conversion fns return a byte array for writing to output stream to an extrnal server. For variable length types (DECIMAL, TIMESTAMP, VARCHAR) the first two bytes are the length of the "data bytes" Note: If a padding byte is needed to make the sequence even in length that must be done by the fns that actually write the bytes to the stream.
