Examples of java.nio.MappedByteBuffer.load()

java.nio.MappedByteBuffer.load()
Loads this buffer's content into physical memory.
This method makes a best effort to ensure that, when it returns, this buffer's content is resident in physical memory. Invoking this method may cause some number of page faults and I/O operations to occur.
@return This buffer

      long overlapStartByte = runningNumBytesRead + thisByteOffset;
      byte[] overlapBytes = new byte[filterLength];
      try {
        MappedByteBuffer overlapBuffer = fileChannel.map(
                 MapMode.READ_ONLY, overlapStartByte, filterLength);
        overlapBuffer.load();
        overlapBuffer.get(overlapBytes, 0, filterLength);
      } catch (Exception e) {
        WError.showError( "Unable to read file " + featuresFile + ".",
                          "BEViewer file read error", e);
        throw new RuntimeException("File error");
