Method Detail
-
addProcessFactory
public static void addProcessFactory(ProcessFactory factory)
Dynamically register a new process factory into SPI
-
removeProcessFactory
public static void removeProcessFactory(ProcessFactory factory)
Dynamically removes a process factory from SPI. Normally the factory has been added before viaaddProcessFactory(ProcessFactory)
-
getProcessFactories
public static Set<ProcessFactory> getProcessFactories()
Set of available ProcessFactory; each of which is responsible for one or more processes.- Returns:
- Set of ProcessFactory
-
createProcessFactory
public static ProcessFactory createProcessFactory(Name name)
Look up a Factory by name of a process it supports.- Parameters:
name
- Name of the Process you wish to work with- Returns:
- ProcessFactory capable of creating an instanceof the named process
-
createProcess
public static Process createProcess(Name name)
Look up an implementation of the named process on the classpath.- Parameters:
name
- Name of the Process to create- Returns:
- created process
-
getParameterInfo
public static Map<String,Parameter<?>> getParameterInfo(Name name)
Look up an implementation of the named process on the classpath and describe the input parameter required.- Parameters:
name
- Name of the Process- Returns:
- Description of the parameters required
-
getResultInfo
public static Map<String,Parameter<?>> getResultInfo(Name name, Map<String,Object> parameters)
Look up an implementation of the named process on the classpath and describe the expected results.Note the expected results are generated in part by the input parameters provided; this is to allow for processes where the output is controlled by the parameters (such as choosing a greyscale or color raster product; or choosing the version of GML produced etc...).
- Parameters:
name
- Name of the Process- Returns:
- Description of the parameters required
-
createCallable
public static Callable<Map<String,Object>> createCallable(Process process, Map<String,Object> input)
Used to wrap a Process up as a Callable for use with an existing ExecutorService
-
newProcessExecutor
public static ProcessExecutor newProcessExecutor(int nThreads)
-
newProcessExecutor
public static ProcessExecutor newProcessExecutor(int nThreads, ThreadFactory threadFactory)
-
reset
public static void reset()
Reinitializes all static state, including the ProcessFactory service registry and reference to the last used ProcessFactory
