Interface KeyValuesLoader

All Known Implementing Classes:

KeyValuesLoader.Builder

public interface KeyValuesLoader

Represents a loader responsible for loading KeyValues from configured sources. This interface defines the contract for loading key-value pairs, potentially involving interpolation or resource chaining.

Implementations of this interface may load key-values from various sources such as files, classpath resources, or system properties.

Method Details

load

KeyValues load()
        throws IOException,
FileNotFoundException,
NoSuchFileException,
KeyValuesException,
UncheckedIOException

Loads key-values from configured sources.

Returns:

a KeyValues instance containing the loaded key-value pairs

Throws:

IOException - if an I/O error occurs during loading

FileNotFoundException - if a specified resource is not found (old io)

NoSuchFileException - if a specified resource is not found (nio)

KeyValuesException - if an error occurs while processing keys such as interpolation or invalid resource keys.

UncheckedIOException - if an IO error happens that had to be wrapped. Some loaders may throw an unchecked IO because of the difficulty of checked exceptions. The KeyValues system will unwrap the exception and check if it is one of the previous missing resource exceptions.
