Class BSPSubsector

java.lang.Object
net.mtrop.doom.bsp.data.BSPSubsector
All Implemented Interfaces:
BinaryObject
public class BSPSubsector extends Object implements BinaryObject

      Parameters:
      segCount - the amount of segments.
      Throws:
      IllegalArgumentException - if the provided value is outside the range 0 to 65535.

    • getSegStartIndex

      public int getSegStartIndex()
      Returns:
      the starting offset index of this subsector's BSPSegments in the Segs lump.

    • setSegStartIndex

      public void setSegStartIndex(int segStartIndex)
      Sets the starting offset index of this subsector's BSPSegments in the Segs lump.

      IllegalArgumentException - if the provided value is outside the range 0 to 65535.

    • readBytes

      public void readBytes(InputStream in) throws IOException
      Description copied from interface: BinaryObject
      Reads from an InputStream and sets this object's fields. Only reads the amount of bytes that it takes to read a single instance of the object. Note that not every object may have a consistent length!
      Specified by:
      readBytes in interface BinaryObject
      Parameters:
      in - the InputStream to read from.
      Throws:
      IOException - if a read error occurs.

    • writeBytes

      public void writeBytes(OutputStream out) throws IOException
      Description copied from interface: BinaryObject
      Writes this object to an OutputStream.
      Specified by:
      writeBytes in interface BinaryObject
      Parameters:
      out - the OutputStream to write to.
      Throws:
      IOException - if a write error occurs.
