Class ProcessStarter

java.lang.Object
org.im4java.process.ProcessStarter
Direct Known Subclasses:
ImageCommand
public class ProcessStarter extends Object
This class implements the processing of os-commands using Runtime.exec(). The class does not use the newer ProcessBuilder, since it has no knowledge about the valid os-arguments of the generated command.

  • Field Details

    • BUFFER_SIZE

      public static final int BUFFER_SIZE
      Buffer size of process input-stream (used for reading the output (sic!) of the process). Currently 64KB.
