Method Details

add

public void add(int index,
 byte[] value)

Add an element to the given record index. This is similar to the set() method in other value vectors, except that it permits setting multiple values for a single record.

Parameters:

index - record of the element to add

value - value to add to the given row

addSafe

public void addSafe(int index,
 byte[] bytes)

addSafe

public void addSafe(int index,
 byte[] bytes,
 int start,
 int length)

setSafe

public void setSafe(int index,
 RepeatedVarCharHolder h)

addSafe

public void addSafe(int index,
 VarCharHolder holder)

addSafe

public void addSafe(int index,
 NullableVarCharHolder holder)

fillEmpties

public void fillEmpties(int lastWrite,
 int index)

Backfill missing offsets from the given last written position to the given current write position. Used by the "new" size-safe column writers to allow skipping values. The set() and setSafe() do not fill empties. See DRILL-5529.

Parameters:

lastWrite - the position of the last valid write: the offset to be copied forward

index - the current write position to be initialized

addSafe

public void addSafe(int rowIndex,
 int start,
 int end,
 DrillBuf buffer)

add

protected void add(int index,
 VarCharHolder holder)

add

public void add(int index,
 RepeatedVarCharHolder holder)

generateTestData

public void generateTestData(int valCount)

Specified by:

generateTestData in interface ValueVector.Mutator

Overrides:

generateTestData in class BaseValueVector.BaseMutator

reset

public void reset()

Description copied from interface: ValueVector.Mutator

Resets the mutator to pristine state.

Specified by:

reset in interface ValueVector.Mutator

Overrides:

reset in class BaseValueVector.BaseMutator
