public static BlockCompare get(int xStartOffset,
                               int xEndOffset,
                               int yStartOffset,
                               int yEndOffset)
```
    Compare block X and Y.
    
    Parameters:
    
    xStartOffset - start offset of block X.
    
    xEndOffset - end offset of block X must be >=xStartOffset.
    
    yStartOffset - start offset of block Y.
    
    yEndOffset - end offset of block Y must be >=yStartOffset.
    
    Returns:
    
    instance of block comparing of X to Y.
  - before
```
public boolean before()
```
    Check if block X is before block Y.
    
    Returns:
    
    true if end offset of block X is <= start offset of block Y i.e.
    xEndOffset <= yStartOffset.
  - after
```
public boolean after()
```
    Check if block X is after block Y.
    
    Returns:
    
    true if start offset of block X is >= end offset of block Y i.e.
    xStartOffset >= yEndOffset.
  - inside
```
public boolean inside()
```
    Check if block X is contained in block Y.
    
    Returns:
    
    true if block X is contained inside block Y i.e. xStartOffset >= yStartOffset && xEndOffset <= yEndOffset.
  - insideStrict
```
public boolean insideStrict()
```
    Check if X is inside Y but X and Y are not equal.
    
    Returns:
    
    true if X is inside Y but they are not equal.
  - contains
```
public boolean contains()
```
    Check if block X contains block Y.
    
    Returns:
    
    true if block X contains block Y.
  - containsStrict
```
public boolean containsStrict()
```
    Check if X contains Y but X and Y are not equal.
    
    Returns:
    
    true if X contains Y but they are not equal.
  - equal
```
public boolean equal()
```
    Check if block X has the same boundaries as block Y.
    
    Returns:
    
    true if start and end offsets of block X are equal to start and end offsets of block Y.
  - overlap
```
public boolean overlap()
```
    Check if there's an overlap at start or end.
    
    Returns:
    
    true overlapStart() || overlapEnd().
  - overlapStart
```
public boolean overlapStart()
```
    Check if block X overlaps block Y at its begining.
    
    Returns:
    
    true if start offset of block X is before start offset of block Y and end offset of block X is inside block Y i.e.
    xStartOffset < yStartOffset and
    xEndOffset > yStartOffset and xEndOffset < yEndOffset.
  - overlapEnd
```
public boolean overlapEnd()
```
    Check if block X overlaps block Y at its end.
    
    Returns:
    
    true if start offset of block X is inside block Y and end offset of block X is above end of block Y i.e.
    xStartOffset > yStartOffset && xStartOffset < yEndOffset
    xEndOffset > yEndOffset.
  - emptyX
```
public boolean emptyX()
```
    Check if block X is empty.
    
    Returns:
    
    true if start offset of block X equals to end offset of block X.
  - emptyY
```
public boolean emptyY()
```
    Check if block Y is empty.
    
    Returns:
    
    true if start offset of block Y equals to end offset of block Y.
  - invalidX
```
public boolean invalidX()
```
    Check if block X has invalid bounds (start offset higher than its end offset).
    
    Returns:
    
    true if X has start offset higher than end offset i.e.
    xStartOffset > xEndOffset.
    If true the block is treated as empty (end offset value is explicitly corrected to the start offset value) and the rest of flags is set accordingly.
    
    Since:
    
    1.49
  - invalidY
```
public boolean invalidY()
```
    Check if block Y has invalid bounds (start offset higher than its end offset).
    
    Returns:
    
    true if Y has start offset higher than end offset i.e.
    yStartOffset > yEndOffset.
    If true the block is treated as empty (end offset value is explicitly corrected to the start offset value) and the rest of flags is set accordingly.

  - equalStart
```
public boolean equalStart()
```
