Method Details

getVectorWithValues

public VarCharVector getVectorWithValues()

setIndexDefined

public void setIndexDefined(int index)

Description copied from interface: NullableVectorDefinitionSetter

Set value at position "index" to be defined.

Specified by:

setIndexDefined in interface NullableVectorDefinitionSetter

Parameters:

index - value position

setIndexDefined

public void setIndexDefined(int index,
 int numValues)

Set a contiguous set of values starting at position "index" to be defined.

Specified by:

setIndexDefined in interface NullableVectorDefinitionSetter

Parameters:

index - value position

numValues - of contiguous values

set

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

Set the variable length element at the specified index to the supplied value.

Parameters:

index - position of the bit to set

value - value to write

fillEmpties

protected void fillEmpties(int index)
