    • setFlag

      public static final void setFlag(COSDictionary dic, String field, int bitFlag, boolean value)
      Deprecated.
      use setFlag(COSDictionary, COSName, int, boolean) using COSName constants instead
      Sets the given boolean value at bitPos in the flags.
      Parameters:
      dic - The dictionary to set the value into.
      field - The name of the field to set the value into.
      bitFlag - the bit position to set the value in.
      value - the value the bit position should have.
    • setFlag

      public static final void setFlag(COSDictionary dic, COSName field, int bitFlag, boolean value)
