Method Detail

multiValued

public static <T> DataRow<Set<TObject>,Set<T>> multiValued(Map<String,Set<TObject>> data)

Parameters:

results -

Returns:

the converted results in the form of a Map whose toString() method does pretty printing

singleValued

public static <T> DataRow<TObject,T> singleValued(Map<String,TObject> data)

Return a DataRow that contains single value cells TObject values that are converted to their Java equivalents.

Parameters:

data -

Returns:

the DataTable

$prettyMapSupplier

protected Supplier<Map<String,T>> $prettyMapSupplier()

Return a Supplier of a Map instance that outputs a pretty string.

Returns:

an empty Map
