Class PropertiesConfigParser

java.lang.Object
  com.webhydra.slug.PropertiesConfigParser

All Implemented Interfaces:

ISlugConfigParser

public class PropertiesConfigParser
extends java.lang.Object
implements ISlugConfigParser

Property configuration parser. Loads and instantiates all ISlugRunner runners from a properties file.

The file format is as follows:

slug.runners

property defining a comma separated list of runner names. Each runner's name is a token composed by alphanumeric characters

slug.runner[runner's name].impl

defiens the ISlugRunner implementation class name for a runner's name defined in slug.runners property

slug.runner[runner's name].param[param name]

defines name/value pair parameter to the ISlugRunner implementation initialization. The name is used as provided by the param name and property's value is passed as a value for it. Zero or many parameters may be defined for each ISlugRunner implementation instance

slug.translatorsr

property defining a comma separated list of translator names. Each runner's name is a token composed by alphanumeric characters

slug.translator[translator's name].impl

defiens the IProcessStatusTranslator implementation class name for a translator's name defined in slug.translators property

slug.translator[translator's name].param[param name]

defines name/value pair parameter to the IProcessStatusTranslator implementation initialization. The name is used as provided by the param name and property's value is passed as a value for it. Zero or many parameters may be defined for each IProcessStatusTranslator implementation instance

Example properties file

 slug.runners=good,param_test
 slug.runner[good].runnerimpl=com.webhydra.slug.process.UnlimitedProcessRunner
 slug.runner[param_test].runnerimpl=com.webhydra.slug.SlugRunnerParamTest
 slug.runner[param_test].param[p1]=Test Patameter 1
 slug.runner[param_test].param[p2]=Test Parameter 2
