Class LvgCmdApiResourceImpl

java.lang.Object

org.apache.ctakes.lvg.resource.LvgCmdApiResourceImpl

All Implemented Interfaces:

LvgCmdApiResource

public class LvgCmdApiResourceImpl
extends java.lang.Object
implements LvgCmdApiResource

Loads NLM Lvg and Norm, reading configuration information from a config (properties) file Since the value of the LVG_DIR property in the lvg properties file must be either a hard coded absolute pathname or the value AUTO_MODE, and we want to support installing this project in a directory of the user's choice, we avoid using a hardcoded pathname and choose to use LVG_DIR=AUTO_MODE in the properties file. AUTO_MODE indicates to lvg to look in the current working directory for its files, so using AUTO_MODE requires this class to change the current working directory temporarily so the lvg files can be found by lvg.

getCurrentWorkingDirectory

private java.lang.String getCurrentWorkingDirectory()

changeCurrentWorkingDirectory

private boolean changeCurrentWorkingDirectory(java.lang.String s)

getLvgDir

private java.lang.String getLvgDir(java.io.File configFile)

Get the path to the root directory of the installation of NLMs lvg lexical tools. Note, does not look at the LVG_DIR properties in the lvg properties file because LVG_DIR might not contain a path - LVG_DIR=AUTO_MODE. Assumes the lvg properties file is in data\config\. For example, if LVG project is installed into
/pipeline/LVG
with the lvg.properties file therefore in
/pipeline/ctakes-lvg/resources/ctakes-lvg/data/config/
this method will return
/pipeline/ctakes-lvg/resources/lvg
