ReverseLineReader

java.lang.Object
- ghidra.framework.main.logviewer.model.ReverseLineReader

```
public class ReverseLineReader
extends java.lang.Object
```
Reads in a single line of text from a given input file, in reverse order. CONOPS: 1. Start at a given position in the file and read BUFFER_SIZE bytes into a byte array 2. From the end of the array, read a character 3. If the character represents a newline (or carriage return), the line is finished, so return. 4. If not, continue reading.

public java.lang.String readLine()
                          throws java.io.IOException
```
    Reads a single line from the current file pointer position, in reverse. To do this we do the following: 1. Read a 'large enough' number of bytes into a buffer (enough to guarantee a full line of text. 2. Move backwards through the bytes just read until a newline or carriage return is found. 3. Throw away the rest of the bytes and return the line found.
    
    Returns:
    
    Throws:
    
    java.io.IOException
