## ◆ expand()

template<typename ValueType, typename CodecType>

void expand | ( | bool | fill = true | ) |

If this array is uniform, replace it with an array of length size().

Parameters

  fill | if true, assign the uniform value to each element of the array.

## ◆ fill()

template<typename ValueType, typename CodecType>

void fill | ( | const ValueType & | value | ) |

Fill the existing array with the given value.

Note
  Identical to collapse() except a non-uniform array will not become uniform.
