Description copied from class: TreeReaderFactory.TreeReader

Populates the isNull vector array in the previousVector object based on the present stream values. This function is called from all the child readers, and they all set the values based on isNull field value.

Overrides:

nextVector in class TreeReaderFactory.TreeReader

Parameters:

previousVector - The columnVector object whose isNull value is populated

isNull - Whether the each value was null at a higher level. If isNull is null, all values are non-null.

batchSize - Size of the column vector

Throws:

IOException
