Constructor Detail

DataVector

public DataVector(DataObject... items)

Constructs a new DataVector containing the items passed as an array or a variable-length list of DataObjects.

Method Detail

size

public int size()

isMissing

public boolean isMissing(int i)

get

public DataObject get(int i)

get

public DataObject[] get()

Returns a shallow copy> of the array of items of this DataVector. Since this method allocates a new array, if only read access to items is needed and the array of items is not going to be modified, it is recommended to use get(int) method instead, which does not allocate new resources. Here, the existing array could not be returned, as this would violate immutability of data objects (the returned array could be modified afterwards, which would indirectly modify this DataVector object).
