Method Detail

init

public void init(Map<String,String> parameters)
          throws MConfigurationException

Initializes the config holder. The following parameters are expected :

• configholder.factoryimpl : Factory implementation class.
• xmlconfigholder.xmlfile : a way to access xml file :
  • File in classpath
  • Full file system path (file:///[FILE_PATH])
    XOR
    xmlconfigholder.xmlcontent : directly the XML content.

Specified by:

init in interface IRuleEngineConfigHolder

Overrides:

init in class AbstractRuleEngineConfigHolder

Throws:

MConfigurationException

getConfigHash

public String getConfigHash()
                     throws XMLMConfigurationException

Description copied from interface: IRuleEngineConfigHolder

Retrieves a complexe hashcode of this config, allowing to detect changes. For example :

• MD5 (at least) of an XML file
• Last change date / hour / milli
• ...

Implementations should compute hash at first call and store it in a cache.

Throws:

XMLMConfigurationException

build

public IMRuleExecutionSet build()
                         throws MConfigurationException

Description copied from interface: IRuleEngineConfigHolder

Builds the config using the internal hold config.

Throws:

MConfigurationException

getFactory

public IRuleExecutionSetXMLFactory getFactory()
                                       throws MConfigurationException

Description copied from class: AbstractRuleEngineConfigHolder

Returns factory instance, depending on requested implementation and compilation level.

Specified by:

getFactory in interface IRuleEngineConfigHolder

Overrides:

getFactory in class AbstractRuleEngineConfigHolder

Throws:

MConfigurationException

getXmlContent

protected String getXmlContent()
                        throws XMLMConfigurationException

Retrieves XML Content from buildXmlInputSource() if not available, to compute HASH.

Throws:

XMLMConfigurationException

getXmlInputSource

protected InputSource getXmlInputSource()
                                 throws XMLMConfigurationException

Retrieves XML Content for building : from available XML Content if exists, or from buildXmlInputSource().

Throws:

XMLMConfigurationException

buildXmlInputSource

protected InputSource buildXmlInputSource()
                                   throws XMLMConfigurationException

Build XML input source from requested file.
This method should be overriden if source is not a file, but DB for example.

Throws:

XMLMConfigurationException
