setup

tearDown

testVarChar

public void testVarChar()

testNullableVarChar

public void testNullableVarChar()

Verify the delicate, fragile logic for setting the value count and filling empty values. Some operators and readers first write values, then set the value count at the end of the batch. The "complex writers" set the value count after each value. The "lastSet" count tracks the last value actually written, but is set in fillEmpties(), which is also called when setting the value count.
