GHNClientContext

public GHNClientContext()

Method Detail

initialise

protected void initialise()
                   throws Exception

Used internally to initialise the context at class loading time.

Overrides:

initialise in class GHNContext

Throws:

Exception - if the context could not be initialised.

configureGHN

protected void configureGHN(File file)
                     throws Exception

Used internally to load external configuration.

Overrides:

configureGHN in class GHNContext

Parameters:

file - the configuration file.

Throws:

Exception - if it could not load external configuration

configureGHNResource

protected void configureGHNResource()
                             throws Exception

Used internally to configure the GCUBEHostingNode resource that models the local gHN.

Overrides:

configureGHNResource in class GHNContext

Throws:

Exception - if the resource could not be configured

getProperty

public Object getProperty(String prop,
                          boolean... required)
                   throws RuntimeException

Resolve a configuration property against the naming service. Resolution is relative to the root JNDI context of the naming service and the JNDI name associated with the context.

Overrides:

getProperty in class GCUBEContext

Parameters:

prop - the property.

required - (optional) true if the property is required, false or omitted if property is optional. The only implication is a different handling of failure and logging. Failure in resolving optional properties results in a runtime exception and fatal log entry, whereas failure in resolving optional properties results in a null result and warning in the log.

Returns:

the value of the property, or null if the property was optional and could not be resolved.

Throws:

RuntimeException - if the property is required but cannot be resolved.
