advance

public boolean advance(StructureQueryConstraint.Acceptor acceptor)

Description copied from interface: StructureQueryConstraint.Sequence

Attempts to advance in this sequence by 0, 1 or more positions (i.e., attempts to find the next 0, 1 or more matching indices). Each position should be passed to acceptor through calls to acceptor.accept(index) or acceptor.accept(indices). Return value indicates whether this sequence is capable of producing values: false indicates the end of this sequence.

Specified by:

advance in interface StructureQueryConstraint.Sequence

Parameters:

acceptor - accepts members of this sequence

Returns:

false iff this sequence does not have any more values
