public class TestFillEmpties
extends SubOperatorTest

Test the "fill empties" logic for all types for all modes. This test exploits the dynamic typing ability of the accessors. Creating an object per value is too slow for production code, but very handy for tests such as this.

Note that this test also has the handy side-effect of testing null handling in the accessor classes.

Method Detail

testFillEmptiesRequired

public void testFillEmptiesRequired()

Test "fill empties" for required types. Here, the fill value is more of a convention: 0 (fixed-width) or an empty entry (variable width.) Some fill value is required to avoid the alternatives which are either 1) leave the value as garbage, or 2) raise an exception about the missing value.

testFillEmptiesNullable

public void testFillEmptiesNullable()

Test "fill empties" for nullable types which are the most "natural" type for omitted values. Nullable vectors fill empties with nulls.

testFillEmptiesRepeated

public void testFillEmptiesRepeated()

Test "fill empties" for repeated types. Drill defines a null (omitted) array as the same thing as a zero-length array.

testDefaultValue

public void testDefaultValue()

Test each vector type to ensure it supports setting a default value. Sets the default directly on the write to avoid the need to serialize the default value to string, which is awkward for some types when using the generic "test value from int" tool.

testDefaultInSchema

public void testDefaultInSchema()

Test the more typical case in which the default value is set in the column metadata. The reader mechanism will automatically set the default for the column writer from the (properly formed) default value in the column metadata.

testInvalidDefault

public void testInvalidDefault()

testBitFillEmpties

public void testBitFillEmpties()

Bit vector is special; packs 8 values per byte. Use custom logic to ship entire bytes.

testBitDefaultValue

public void testBitDefaultValue()
