Class IntervalYearVector.Mutator

java.lang.Object

org.apache.drill.exec.vector.BaseValueVector.BaseMutator

org.apache.drill.exec.vector.IntervalYearVector.Mutator

All Implemented Interfaces:

ValueVector.Mutator

Enclosing class:

IntervalYearVector

public final class IntervalYearVector.Mutator
extends BaseValueVector.BaseMutator

IntervalYear.Mutator implements a mutable vector of fixed width values. Elements in the vector are accessed by position from the logical start of the vector. Values should be pushed onto the vector sequentially, but may be randomly accessed.

• The width of each element is IntervalYearVector.VALUE_WIDTH (= 4) byte(s).
• The equivalent Java primitive is 'int'

NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.

Method Detail

set

public void set(int index,
                int value)

Set the element at the given index to the given value. Note that widths smaller than 32 bits are handled by the DrillBuf interface.

Parameters:

index - position of the bit to set

value - value to set

setSafe

public void setSafe(int index,
                    int value)

Set the value of a required or nullable vector. Grows the vector as needed. Does not enforce size limits; scalar fixed-width types can never overflow a vector.

Parameters:

index - item to write

set

protected void set(int index,
                   IntervalYearHolder holder)

setSafe

public void setSafe(int index,
                    IntervalYearHolder holder)

set

protected void set(int index,
                   NullableIntervalYearHolder holder)

setSafe

public void setSafe(int index,
                    NullableIntervalYearHolder holder)

generateTestData

public void generateTestData(int size)

Specified by:

generateTestData in interface ValueVector.Mutator

Overrides:

generateTestData in class BaseValueVector.BaseMutator

generateTestDataAlt

public void generateTestDataAlt(int size)

setValueCount

public void setValueCount(int valueCount)

Description copied from interface: ValueVector.Mutator

Sets the number of values that is stored in this vector to the given value count. WARNING! Once the valueCount is set, the vector should be considered immutable.

Parameters:

valueCount - value count to set.
