Constructors
Usmap(String)
Reads a .usmap file from disk and initializes a new instance of the Usmap class to store its data in memory.
public Usmap(string path)
Parameters
path String
The path of the file file on disk that this instance will read from.
Exceptions
FormatException
Throw when the file cannot be parsed correctly.
Usmap(UsmapBinaryReader)
Reads a .usmap file from a BinaryReader and initializes a new instance of the Usmap class to store its data in memory.
public Usmap(UsmapBinaryReader reader)
Parameters
reader UsmapBinaryReader
The file's BinaryReader that this instance will read from.
Exceptions
FormatException
Throw when the asset cannot be parsed correctly.
Usmap()
Initializes a new instance of the Usmap class. This instance will store no data and does not represent any file in particular until the Usmap.ReadHeader(UsmapBinaryReader) method is manually called.
