Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
HCL OneDB™ JDBC Driver GuideThe HCL OneDB™ JDBC Driver Programmer's Guide describes how to install, load, and use HCL OneDB™ JDBC Driver to connect to the HCL OneDB™ database from within a Java™ application.
Appendixes
Convert internal HCL OneDB™ data typesFor your Java™ application to work with the internal server representation of HCL OneDB™ data types, use the IfxToJavaType class. For example, if your application is using the HCL® OneDB® Change Data Capture API, you can use the IfxToJavaType class to interpret the byte stream.
The IfxToJavaType classThe IfxToJavaType class handles all the HCL OneDB™ to Java™ data type conversions. Separate methods are provided for converting each HCL OneDB™ data type.
The IfxToJavaDouble() methodThe IfxToJavaDouble() method converts the HCL OneDB™ DOUBLE PRECISION data type to the Java™ double data type.

The IfxToJavaDouble() method

The IfxToJavaDouble() method converts the HCL OneDB™ DOUBLE PRECISION data type to the Java™ double data type.

Method signature

public static double IfxToJavaDouble (byte b [], short prec)
public static double IfxToJavaDouble (byte b [])
public static double IfxToJavaDouble (byte b [], int offset, int length,
       short prec)
public static double IfxToJavaDouble (byte b [], int offset)

Input parameters

b: The bytes encoding data
offset: The offset into byte array.
prec: The precision as received from HCL OneDB.
length: The data length.
