## com.bea.content.loader.bulk
Class BulkLoader

    java.lang.Object
      com.bea.content.loader.bulk.BulkLoader

All Implemented Interfaces:
  FilenameFilter

public class BulkLoader
extends Object
implements FilenameFilter

The Content Manager bulk loader application.

This class will scan the local file system for files to load via the NodeOps and WorkspaceOps api.

BulkLoader has limited use when loading against a Library Services Enabled Repository. If the content is new (not currently loaded into the BEA Repository) and Library Services is enabled, the content may be loaded. In this case, the lifecyclestatus must be specified in the md.properties, which defines the status the content will be checked in as. All lifecycle actions will operate as if the bulkloader user is a user in the adminn tools. So if a content item is checked in as "Ready" then the assignements will occur. Please review the `LifeCycle` javadoc for valid statuses, status transitions and how the system operates for each specific transition. Valid transition values (integer values) for BulkLoader md.properties are as follows:

- 1 = DRAFT
- 2 = READY
- 4 = PUBLISHED
- 5 = RETIRED

  The type (ObjectClass) for the file along with the values of any required properties must be specified in the metata data properties file. Thus, a type must be defined in the content repository before the bulkloader may load files from the file system.

  A folder will be loaded as a Hierarchy Node and a file will be loaded as a Content Node.

  The actual bytes will be loaded into the primary property (must be defined in the type) and must be of type Binary.

  In order for bulkloader to run, the repository and the application must be passed in as arguments and the server must be running.

  This class is mainly designed to run as a command-line application, via a "java com.bea.content.loader.bulk.BulkLoader" command-line. To see a usage, give it a -h flag or read the Usage.txt in this package.

  Additionally, BulkLoader objects can be created and used to provide the functionality in other places. The lifecycle of a BulkLoader is as follows:

  The base directory that will be loaded may be passed in using the -d paramter. If it is not specified then the current directory "." will be used. Any additional argument will be considered a file/folder to load relative to the base directory, or if an absolute path is specified then it will be used.

  - Construction
  - `parseArgs()` if not passed in to constructor.
  - `validateArgs()` to make sure the loader has valid arguments.
  - `doLoad()` to execute the load.
  Not calling parseArgs() and validateArgs(), in that order, will cause the BulkLoader object to most likely ungracefully fail. However, once those methods have been invoked, doLoad(), can invoked.

  If manually constructing and utilizing a BulkLoader object, be certain to synchronize all access to the object. Since the command-line program is single-threaded, BulkLoader objects are not thread-safe by design.

  To load the default `LoaderFilters`, the BulkLoader looks for the com/bea/content/loader/bulk/loader.properties file in the CLASSPATH. From that it reads the list of default LoaderFilter class names from the "loader.defFilters" property. To not use any of the default filters, specify +filters in the command-line args.

  If BulkLoader fails with an out of memory error you should increase your java heap size. You may do this in the bulkloader script by passing -Xms???m into the java call where ??? is the number of megabytes.

    2.0

    Throws:
      `Exception`

  ### isHidden

      public static boolean isHidden(File f)

    Check if the specified file is a hidden file.

    Under UNIX, the File.isHidden() reports that "/weblogicCommerce/dmsBase/." is a hidden file, which it is not. So, this fixes that problem by getting canonicals paths for directories before calling isHidden(). That seems to do the trick.

  ### isHtmlFile

      public boolean isHtmlFile(String name)

    Tell if the specified file name is an HTML file to the loader.

  ### isReadableDirectory

      public static boolean isReadableDirectory(String name)

  ### loadIndividualFile

      public void loadIndividualFile(File f,
                                     String path,
                                     Properties mdProperties)
                              throws Exception

    Throws:
      `Exception`

  ### main

      public static int main(BulkLoader loader,
                             String[] args)

    The main method invoked on a BulkLoader instance.

    This will take a BulkLoader through the bulk loading steps. Output will be sent via the BulkLoader's `debug()`, `warning()`, and `error()` methods.

    This will not call System.exit().

    Parameters:
      `args` - the command-line args.
    Returns:
      the exit code (0 for success, non-zero for failure).
    See Also:
      `parseArgs(java.lang.String[])`, `validateArgs()`

  ### main

      public static void main(String[] args)

    Command-line entry point.

    This will call System.exit() on invalid args or error. To invoke a bulk load from your own code, create and manipulate a BulkLoader object. You can use the other main method, which does not exit.

    Parameters:
      `args` - the command-line args.
    See Also:
      `main(com.bea.content.loader.bulk.BulkLoader, java.lang.String[])`

  ### parseArgs

      public void parseArgs(String[] args)
                     throws IllegalArgumentException

    Parse the given input arguments.

    Parameters:
      `args` - the input arguments.
    Throws:
      `BulkLoader.ShowUsageException` - thrown if the caller should show a usage report.
      `IllegalArgumentException` - thrown on bad arguments.

  ### printArgs

      public void printArgs()

    Prints the arguments as debug statements.

  ### processBatchProperties

      public void processBatchProperties()
                                  throws Exception

    Throws:
      `Exception`

  ### shouldIgnore

      public boolean shouldIgnore(String name)

    Tell if the loader should ignore the specified file name.

  ### shouldInclude

      public boolean shouldInclude(String name)

    Tell if the loader should include the specified file name.

  ### usage

      public void usage()

    Print the usage of the application.

  ### usage

      public void usage(PrintWriter out)

    Print the usage of the application.

  ### validateArgs

      public void validateArgs()
                        throws IllegalStateException

    Validate that we have been passed correct arguments.

    This does not validate that the arguments are valid. That will be done in initialize().

    Throws:
      `IllegalStateException`

  ### warning

      public void warning(String mesg)

    Output a warning message.

  ### warning

      public void warning(String mesg,
