Method Detail

matches

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
