Writes into this vector instance.

Method Summary

Modifier and Type	Method and Description
void	exchange(ValueVector.Mutator other) Exchanges state with the mutator of another mutator.
void	generateTestData(int values) Deprecated. this has nothing to do with value vector abstraction and should be removed.
void	reset() Resets the mutator to pristine state.
void	setValueCount(int valueCount) Sets the number of values that is stored in this vector to the given value count.

Method Detail

setValueCount

void setValueCount(int valueCount)

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.

reset

void reset()

Resets the mutator to pristine state.

generateTestData

@Deprecated
void generateTestData(int values)

Deprecated. this has nothing to do with value vector abstraction and should be removed.

exchange

void exchange(ValueVector.Mutator other)

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