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

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, context IContext) (config map[string]interface{}, err error)

• ctx: context.Context - operation context.
• context: IContext - (optional) a context to trace execution through a 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.
