  • Method Details

    • 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 via addProcessFactory(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
