Method Detail

getList

public List<?> getList(Object data)

Description copied from interface: ListObjectInspector

returns null for data = null. Note: This method should not return a List object that is reused by the same ListObjectInspector, because it's possible that the same ListObjectInspector will be used in multiple places in the code. However it's OK if the List object is part of the Object data.
