Constructor Details
- OmfData
  
  public OmfData()
Method Details
- getSegmentIndex
  
  public int getSegmentIndex()
  
  Returns:
  
  get the segments index for this datablock
- getDataOffset
  
  public long getDataOffset()
  
  Returns:
  
  the starting offset, within the loaded image, of this data
- compareTo
  
  public int compareTo(OmfData o)
  
  Compare datablocks by data offset
  
  Specified by:
  
  compareTo in interface Comparable<OmfData>
  
  Returns:
  
  a value less than 0 for lower address, 0 for same address, or greater than 0 for higher address
- getLength
  
  public abstract int getLength()
  
  Returns:
  
  the length of this data in bytes
- getByteArray
  
  public abstract byte[] getByteArray(BinaryReader reader) throws IOException
  
  Create a byte array holding the data represented by this object. The length of the byte array should exactly match the value returned by getLength()
  
  Parameters:
  
  reader - is for pulling bytes directly from the binary image
  
  Returns:
  
  allocated and filled byte array
  
  Throws:
  
  IOException - for problems accessing data through the reader
- isAllZeroes
  
  public abstract boolean isAllZeroes()
  
  Returns:
  
  true if this is a block entirely of zeroes
