Method Details

createInsertionOrdered

Map<String,Object> createInsertionOrdered(List<String> keys,
 List<Object> values)

The general contract is that the resulting map keeps the insertion orders of keys. Values are nullable but keys are not. Implementations are free to create or to reuse map instances.

Parameters:

keys - the keys like k1, k2, ..., kn

values - the values like v1, v2, ..., vn

Returns:

a new or reused map instance with (k1,v1), (k2, v2), ... (kn, vn)
