Constructor Detail

Lattice.Builder

public Lattice.Builder(CalciteSchema schema,
               String sql)

Method Detail

auto

public Lattice.Builder auto(boolean auto)

Sets the "auto" attribute (default true).

algorithm

public Lattice.Builder algorithm(boolean algorithm)

Sets the "algorithm" attribute (default false).

algorithmMaxMillis

public Lattice.Builder algorithmMaxMillis(long algorithmMaxMillis)

Sets the "algorithmMaxMillis" attribute (default -1).

rowCountEstimate

public Lattice.Builder rowCountEstimate(double rowCountEstimate)

Sets the "rowCountEstimate" attribute (default null).

build

public Lattice build()

Builds a lattice.

resolveArgs

public com.google.common.collect.ImmutableList<Lattice.Column> resolveArgs(Object args)

Resolves the arguments of a JsonMeasure. They must either be null, a string, or a list of strings. Throws if the structure is invalid, or if any of the columns do not exist in the lattice.

resolveColumn

public Lattice.Column resolveColumn(Object name)

resolveMeasure

public Lattice.Measure resolveMeasure(String aggName,
                             Object args)

addMeasure

public void addMeasure(Lattice.Measure measure)

addTile

public void addTile(Lattice.Tile tile)
