Implements: IReferenceable, IConfigurable
Description
The SqliteConnectionResolver class is used to resolve SQLite connections and credential paramters, validate them and generate connection URIs.
Important points
- It is able to process multiple connections to SQLite cluster nodes.
Configuration parameters
- connection(s):
- discovery_key: (optional) a key to retrieve the connection from IDiscovery
- host: host name or IP address
- port: port number (default: 8082)
- database: database name
- uri: resource URI or connection string with all parameters in it
- credential(s):
- store_key: (optional) a key to retrieve the credentials from ICredentialStore
- username: user name
- password: user password
References
- *:discovery:*:*:1.0 - (optional) IDiscovery services
- *:credential-store:*:*:1.0 - (optional) ICredentialStore stores to resolve credentials

Fields
Methods
Configure
Configures a component by passing its configuration parameters.
(c *SqliteConnectionResolver) Configure(ctx context.Context, config *cconf.ConfigParams)
- ctx: context.Context - operation context.
- config: *cconf.ConfigParams - configuration parameters to be set.
Resolve
Resolves a SQLite connection URI from connection and credential parameters.
(c *SqliteConnectionResolver) Resolve(ctx context.Context, correlationId string) (config map[string]interface{}, err error)
- ctx: context.Context - operation context.
- correlationId: string - (optional) transaction id used to trace execution through the call chain.
- returns: (config map[string]interface{}, err error) - resolved config.
SetReferences
Sets references to dependent components.
(c *SqliteConnectionResolver) SetReferences(ctx context.Context, references crefer.IReferences)
- ctx: context.Context - operation context.
- references: crefer.IReferences - references to locate the component’s dependencies.
