Checks whether a certain value is compatible for a column. Compatible means that the value has a type suited for the respective class

Specified by:

isCompatible in class UpdatableRow<String,DataFrameHeader,Comparable>

Parameters:

value - checked value

headerIndex - header index

Returns:

true if value is compatible
