public class MultiDictTerm
extends DictTerm

MultiDictTerm provides the implementation of the TOR operator. The class both extends DictTerm and contains one or more instances of DictTerm. During evaluation, almost all of the DictTerm code is reused in this class with just a little code added in. When setPartition is called, MultiDictTerm will fill in its own list of dict entries with the entries generated by calling setPartition on each of the DictTerms it contains.

Method Detail

setQueryConfig

public void setQueryConfig(QueryConfig qc)

Set the query config for all the sub-terms.

Overrides:

setQueryConfig in class QueryTerm

setPartition

public void setPartition(DiskPartition part)

Overrides the standard DictTerm setPartition. This will call setPartition on all of terms contained in this object, then fill in DictTerm.dictEntries with the dictEntries from all of them.

Overrides:

setPartition in class DictTerm

Parameters:

part - the partition that we will be evaluating against

getName

public java.lang.String getName()

Overrides:

getName in class DictTerm

toString

public java.lang.String toString()

Overrides:

toString in class DictTerm

toString

public java.lang.String toString(java.lang.String prefix)

Overrides:

toString in class DictTerm
