Interface FieldGen

All Known Implementing Classes:

BooleanGen, DateGen, DoubleGen, IntGen, MoneyGen, StringGen, VaryingStringGen

public interface FieldGen

Interface which all mock column data generators must implement. Each has a setup(org.apache.drill.exec.store.mock.ColumnDef) method which is given the column definition for the column. This definition may have additional configuration information for the column (column width, precision, etc.). Each also has a setValue(org.apache.drill.exec.vector.ValueVector, int) method that does the work of setting a specific value vector position to the generated value. The implementation is expected to cast the vector to the type supported by that particular generator. (This is test code; we're not overly concerned with the overhead of such casts.)
