Constructor Detail

SimpleFilter

protected SimpleFilter(IntIterator input)

Parameters:

input - the incoming indices to be filtered (from StructureQueryConstraint.filter(IntIterator, List, QueryContext)

Method Detail

matches

public abstract boolean matches(int index)

Returns true if the row at the specified index matches the criteria.

Parameters:

index - index into the forest being searched

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
