public class EnvVarDestinationLoader extends Object implements DestinationLoader
DestinationLoader implementation reading the destination from an environment variable.
The environment variable is expected to be a JSON array of JSON object containing a field called name. All
other fields of the JSON object will be converted to String and put into the created Destination
object.
Valid example:
destinations='[{"name"="destinationName", "url"="www.sap.de"}, {"name"="destinationName2", "url"="www.sap.com"}]'
| Constructor and Description |
|---|
EnvVarDestinationLoader()
Creates a new instance of
EnvVarDestinationLoader reading the destinations variable from the
system environment variables. |
EnvVarDestinationLoader(Function<String,String> environmentVariableAccessor,
Function<String,DefaultDestination> destinationJsonParser,
String variableName)
Creates a new instance of
EnvVarDestinationLoader reading variable with the provided name from the
provided function. |
EnvVarDestinationLoader(Function<String,String> environmentVariableAccessor,
String variableName)
Creates a new instance of
EnvVarDestinationLoader reading variable with the provided name from the
provided function. |
| Modifier and Type | Method and Description |
|---|---|
io.vavr.control.Try<DefaultDestination> |
loadTypedDestination(String destinationName,
DestinationOptions options)
This executes the same logic as
DestinationLoader.tryGetDestination(String) but provides the returned Destination
in a more specific type. |
io.vavr.control.Try<Destination> |
tryGetDestination(String destinationName,
DestinationOptions options)
Retrieves a destination for the given name and configuration options.

this will fall back to System.getenv(String).destinationJsonParser - A function returning the DefaultDestination after parsing the JSON. If null is passed,
a default implementation is used.variableName - The name of the environment variable to read. If null is passed this will fall back to

EnvVarDestinationLoader reading variable with the provided name from the
provided function.environmentVariableAccessor - A function returning the environment variable for a given name parameter. If null is passed
this will fall back to System.getenv(String).variableName - The name of the environment variable to read. If null is passed this will fall back to
destinations.@Nonnull public io.vavr.control.Try<Destination> tryGetDestination(@Nonnull String destinationName, @Nonnull DestinationOptions options)
The returned Try object will contain a
DestinationAccessException with more details in
case something went wrong.
If the returned Try object contains no Exception it will always contain a non-null Destination
value.
