ByteRangeMap

java.lang.Object
- ghidra.util.datastruct.ByteRangeMap

All Implemented Interfaces:

java.io.Serializable
```
public class ByteRangeMap
extends java.lang.Object
implements java.io.Serializable
```
Stores ranges of byte values throughout "long" space. Every "long" index has an associated byte value (initially 0). Users can paint (set) ranges of indexes to a given byte value, overwriting any value that currently exists in that range. This class is implemented using an BytePropertySet. The first index (0) will always contain a value. The value at any other given index will either be the value stored at that index, or if no value stored there, then the value stored at the nearest previous index that contains a value.

                       long end,
                       byte value)
```
    Associates the given value with every index from start to end (inclusive) Any previous associates are overwritten.
    
    Parameters:
    
    start - the start index of the range to fill.
    
    end - the end index of the range to fill
    
    value - the value to put at every index in the range.
  - getValue
```
public byte getValue(long index)
```
    Returns the int value associated with the given index.
    
    Parameters:
    
    index - the index at which to get the value.
  - getIndexRangeIterator
```
public IndexRangeIterator getIndexRangeIterator(long index)
```
    returns an iterator over the ranges
    
    Parameters:
    
    index - index to start the iterator
    
    Returns:
    
    IndexRangeIterator the iterator over the index ranges
  - getChangePointIterator
```
public LongIterator getChangePointIterator(long start,
                                           long end)
```
    Returns an iterator over all indexes where the values changes.
    
    Parameters:
    
    start - start index of iterator
    
    end - end index of iterator
    
    Returns:
    
    LongIterator the iterator over index values that represent changes in values.
