Mutator

public Mutator()

Method Details

startNewValue

public void startNewValue(int index)

Description copied from interface: RepeatedValueVector.RepeatedMutator

Starts a new value that is a container of cells.

Specified by:

startNewValue in interface RepeatedValueVector.RepeatedMutator

Parameters:

index - index of new value to start

setValueCount

public void setValueCount(int topLevelValueCount)

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.

Specified by:

setValueCount in interface ValueVector.Mutator

Parameters:

topLevelValueCount - value count to set.

reset

public void reset()

Description copied from interface: ValueVector.Mutator

Resets the mutator to pristine state.

Specified by:

reset in interface ValueVector.Mutator

generateTestData

public void generateTestData(int values)

Specified by:

generateTestData in interface ValueVector.Mutator

add

public int add(int index)

exchange

public void exchange(ValueVector.Mutator other)

Description copied from interface: ValueVector.Mutator

Exchanges state with the mutator of another mutator. Used when exchanging state with another vector.

Specified by:

exchange in interface ValueVector.Mutator
