getCollector

public JasmineCollector getCollector(JasmineIndicator indicator,
                                     JasmineProbe probe)
                              throws JasmineCollectorException

Get a Collector for this indicator and this probe. First parse indicator properties, and get a collector for each source. The goal is to 'notify' to sources that an additional 'consumer' collector exists for them. This allows for collectors that manage a cache of values to update cache size.

Specified by:

getCollector in interface JasmineCollectorService

Specified by:

getCollector in class JCollectorService

Parameters:

indicator - the indicator for which values are collected by the collector

probe - the probe using the indicator

Returns:

the JasmineCollector instance created to collect values for the given indicator within the given probe.

Throws:

JasmineCollectorException - The collector could not be created.

getDependantIndicators

public List<String> getDependantIndicators(JasmineIndicator indic)

return the List of indicators used by this indicator.

Specified by:

getDependantIndicators in interface JasmineCollectorService

Overrides:

getDependantIndicators in class JCollectorService

Parameters:

indic - JasmineIndicator

Returns:
