Class WadFile.Adder

java.lang.Object
net.mtrop.doom.WadFile.Adder
All Implemented Interfaces:
AutoCloseable
Enclosing class:
WadFile
public class WadFile.Adder extends Object implements AutoCloseable
Bulk add mechanism for WadFile. All methods on this object manipulate the WadFile it is created from, and defers the final writing of the entry list until it is closed. This object is meant to be created via a try-with-resources block, like so: 
 try (WadFile.Adder adder = wad.createAdder())
 {
     adder.addData(....);
     ...
 }
...upon which the entries are committed on close. This will still commit the list even on an error occurring during add, unless the the writing of the list results in an error as well.
Since:
2.7.0

  • Method Details

    • close

      public void close() throws IOException
      Specified by:
      close in interface AutoCloseable
      Throws:
      IOException

    • addEntry

      public WadEntry addEntry(String entryName, int offset, int length) throws IOException
      Adds a new entry to the Wad, but with an explicit offset and size. Exercise caution with this method, since you can reference anywhere in the Wad!

      NOTE: The entry is not written until close() is called (or the WadFile.Adder is closed automatically).

      Parameters:
      entryName - the name of the entry.
      offset - the entry's content start byte.
      length - the entry's length in bytes.
      Returns:
      the entry that was created.
      Throws:
      IllegalArgumentException - if the provided name is not a valid name, or the offset/size is negative.
      IOException - if the entry cannot be written.
      NullPointerException - if name is null.

    • addMarker

      public WadEntry addMarker(String entryName) throws IOException
      Adds an entry marker to the Wad (entry with 0 size, arbitrary offset).
      Parameters:
      entryName - the name of the entry.
      Returns:
      the entry that was added.
      Throws:
      IllegalArgumentException - if the provided name is not a valid name.
      IOException - if the entry cannot be written.
      NullPointerException - if name is null.

    • addMarkerAt

      public WadEntry addMarkerAt(int index, String entryName) throws IOException
      Adds an entry marker to the Wad (entry with 0 size, arbitrary offset).
      Parameters:
      index - the index at which to add the marker.
      entryName - the name of the entry.
      Returns:
      the entry that was added.
      Throws:
      IllegalArgumentException - if the provided name is not a valid name.
