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.
• mrlconfigholder.mrlfile : a way to access mrl file :
  • File in classpath
  • Full file system path (file:///[FILE_PATH])
    XOR
    mrlconfigholder.mrlcontent : directly the MRL content.

Specified by:

init in interface IRuleEngineConfigHolder

Overrides:

init in class AbstractRuleEngineConfigHolder

Throws:

MConfigurationException

getConfigHash

public String getConfigHash()
                     throws MConfigurationException

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:

MConfigurationException

build

public IMRuleExecutionSet build()
                         throws MConfigurationException

Description copied from interface: IRuleEngineConfigHolder

Builds the config using the internal hold config.

Throws:

MConfigurationException

getMrlContent

protected String getMrlContent()
                        throws MConfigurationException

Retrieves MRL Content for Hash: from available MRL Content if provided, or from file.

Throws:

MConfigurationException

getMrlReader

protected Reader getMrlReader()
                       throws MConfigurationException

Retrieves MRL Content for building: from available MRL Content if provided, or from file.

Throws:

MConfigurationException
