This pull request implements #178 which allows to jump to addresses and make use of stream.Seek() with SeekOrigin.
The default behaviour of FieldOffset has not changed and then it will rewind by default.
Since i have files pointing to tables this will help having a master class rather that multiple classes and jump in between.
Arguments
offset|path
SeekOrigin: Specifies the position in a stream to use for seeking the field (Default: SeekOrigin.Begin)
Rewind: If true it will seek back to position where it was before seek, otherwise stream will continue from the current position (Default: true)
Example:
public class FileSpec
{
[FieldOrder(0)]
[FieldLength(12)]
[SerializeAs(SerializedType.TerminatedString)]
public string FileVersion { get; set; } = "FileMarking";
[FieldOrder(1)]
public uint FileVersion { get; set; }
[FieldOrder(2)]
public uint HeaderAddress { get; set; }
[FieldOrder(3)]
public uint SettingsAddress { get; set; }
[FieldOrder(4)]
public uint PreviewAddress { get; set; }
[FieldOrder(5)]
public uint LayersAddress { get; set; }
[FieldOrder(6)]
[FieldOffset(nameof(HeaderAddress), false)]
public uint HeaderField1 { get; set; }
[FieldOrder(7)]
public uint HeaderField2 { get; set; }
[FieldOrder(8)]
public uint HeaderField3 { get; set; }
[FieldOrder(9)]
[FieldOffset(nameof(SettingsAddress), false)]
public uint SettingsField1 { get; set; }
[FieldOrder(10)]
public uint SettingsField2 { get; set; }
[FieldOrder(11)]
[FieldOffset(nameof(PreviewAddress), false)]
public uint PreviewSize { get; set; }
[FieldOrder(12)]
[FieldCount(nameof(PreviewSize))]
public byte[] PreviewData {get; set; }
[FieldOrder(13)]
[FieldOffset(nameof(LayersAddress), false)]
public uint LayerCount { get; set; }
[FieldOrder(14)]
[FieldCount(nameof(LayerCount))]
public Layer[] Layers { get; set; }
[FieldOrder(15)]
[FieldOffset(4, SeekOrigin.Current, false)] // Skip unused 4 bytes first, same as declaring uint Padding
public uint FileChecksum { get; set; }
}
