drb-driver-java 1.1.0

DRB java driver

JavaNode driver

The drb-driver-java python module aims to wrap Java version of DRB model. It is able to navigates among java nodes content.

See documentation for details.

Library usage

Java must be present in the system

Normally if java is correctly installed, the JAVA_HOME environment variable is set You can check it by command line below

echo $JAVA_HOME

Installing this library with execute the following in a terminal

pip install drb-driver-java

If you want add schema or addon you have eventually CLASSPATH_ADDON to define

export CLASSPATH_ADDON=/path_addon_one/*;

Java Factory and Java Node

The module implements the basic factory model defined in DRB in its node resolver. Based on the python entry point mechanism, this module can be dynamically imported into applications.

The entry point group reference is drb.driver.
The driver name is java.
The factory class DrbJavaFactory is encoded into drb.drivers.factory

The java factory creates a JavaNode from an existing java content. It uses a base node to access the content data using a streamed implementation from the base node.

The base node can be a DrbFileNode, DrbHttpNode, DrbTarNode or any other nodes able to provide streamed (BufferedIOBase, RawIOBase, IO) java content.

limitations

The current version does not manage child modification and insertion. JavaNode is currently read only.

Using this module

To include this module into your project, the drb-driver-java module shall be referenced into requirements.txt file, or the following pip line can be run:

pip install drb-driver-java

Set eventually environment variable CLASSPATH_ADDON and JAVA_HOME
