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

Parameters:

data -

Returns:

the DataTable

entrySet

Specified by:

entrySet in interface Map<String,T>

Specified by:

entrySet in class AbstractMap<String,T>

toString

public String toString()

Overrides:

toString in class AbstractMap<String,T>

transform

protected abstract T transform(F value)

Transform the value to the appropriate type.

Parameters:

value -

Returns:

the transformed value.
