Method Summary

All Methods Static Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`static BondMatcher`	`forAny()`	All bonds are compatible.
`static BondMatcher`	`forOrder()`	Bonds are compatible if they are both aromatic or their orders are equal.
`static BondMatcher`	`forQuery()`	Bonds are compatible if the first `bond1` (an `IQueryBond`) matches the second, `bond2`.
`static BondMatcher`	`forStrictOrder()`	Bonds are compatible if they are both aromatic or their orders are equal and they are non-aromatic.
`abstract boolean`	`matches(IBond bond1, IBond bond2)`	Determines if `bond1` is compatible with `bond2`.

```
public abstract boolean matches(IBond bond1,
                                IBond bond2)
```
    Determines if bond1 is compatible with bond2.
    
    Parameters:
    
    bond1 - a bond from the query structure
    
    bond2 - a bond from the target structure
    
    Returns:
    
    the bonds are compatible
  - forAny
```
public static BondMatcher forAny()
```
    All bonds are compatible.
    
    Returns:
    
    a bond matcher
  - forStrictOrder
```
public static BondMatcher forStrictOrder()
```
    Bonds are compatible if they are both aromatic or their orders are equal and they are non-aromatic. Under this matcher a single/double bond will not match a single/double bond which is aromatic.
    
    Returns:
    
    a bond matcher
  - forOrder
```
public static BondMatcher forOrder()
```
    Bonds are compatible if they are both aromatic or their orders are equal. This matcher allows a single/double bond to match a single/double aromatic bond.
    
    Returns:
    
    a bond matcher
  - forQuery
```
public static BondMatcher forQuery()
```
    Bonds are compatible if the first bond1 (an IQueryBond) matches the second, bond2.
    
    Returns:
    
    a bond matcher
