Method Details

getRowCount

public int getRowCount()

Specified by:

getRowCount in interface TupleVector

getColumn

public ValueVector getColumn(int column)

Description copied from interface: TupleVector

Return vector for provided column. NOTE! Returned value might not be thread safe.

Specified by:

getColumn in interface TupleVector

getSchema

public Schema getSchema()

Description copied from interface: TupleVector

Return the actual schema from the vector. If this tuple vector resides from a schema less query then this is the actual columns resolved runtime else this schema should match the compile time schema that the data source had

Specified by:

getSchema in interface TupleVector

chain

public static TupleVector chain(List<TupleVector> vectors)

Created a chained tuple vector. This returns a single tuple vector that wraps a list of source vectors. This requires that the provided vectors shares a common subset of their schema.
