Package io.trino.tempto.internal.configuration

Class MapConfiguration

java.lang.Object

io.trino.tempto.internal.configuration.AbstractConfiguration

io.trino.tempto.internal.configuration.MapConfiguration

All Implemented Interfaces:

Configuration

public class MapConfiguration
extends AbstractConfiguration

This class constructs and stores a map based configuration using nested maps.

For leafs - value is stored in map. For non-leaf - nested map is stored.

Outer map is responsible for first part in all keys stored in configuration. Maps stored at first internal level are responsible for second part in stored keys and so on.

For example, for a configuration storing these hierarchical entries: a.b.c = 3 a.x = 10 b.c = 15

the following map structure would be created

 {
 a : {
  b : {
   c : 3
  },
  x : 10
  },
 b : {
  c : 15
  }
 }

Method Details

get

public Optional<Object> get(String key)

listKeys

public Set<String> listKeys()

Description copied from interface: Configuration

Lists all keys in configuration

Returns:

List of keys

listPrefixes

public Set<String> listPrefixes()

Description copied from interface: Configuration

Lists configuration key prefixes of length=1

E.g. for configuration with keys: a.b.c a.d.e b

listPrefixes() would return ["a", "b"]

getSubconfiguration

public Configuration getSubconfiguration(String keyPrefix)

Description copied from interface: Configuration

Returns configuration containing all keys starting with given prefix. Keys for returned configuration are stripped of this prefix.

Parameters:

keyPrefix - Prefix to search for

Returns:

Configuration containing all keys starting with given prefix.
