Method Detail

put

Measurable put(Measurable unit)

Description copied from class: UnitsTable

Method to insert a unit in this table. Successful insertion depends on the value of the unit's identifier. If it's not null, then an insertion will be made provided that there is no existing entry of the same name (else an exception will be thrown). If it's null, then no insertion will be ever be made. However, if the unit itself matches an existing unit in the table, then that (matching unit) will be returned. Otherwise, the given unit will be returned.

Overrides:

put in class UnitsTable

Parameters:

unit - the Measurable instance to be inserted.
