Package com.ultikits.ultitools.config.document

Class ConfigLoadResult

java.lang.Object

com.ultikits.ultitools.config.document.ConfigLoadResult

@Internal
public final class ConfigLoadResult
extends Object

What reading one config file found. ConfigDocument.load(Path) returns one of four states and never throws, so a file that exists but cannot be read or parsed is never mistaken for a missing file - the distinction that keeps the framework from overwriting an operator's broken file with defaults (UltiKits/UltiTools-Reborn#511, #470).

Since:

6.3.0

Modifier and Type	Method	Description
(package private) static ConfigLoadResult	absent(Path file)
IOException	cause()	Why the file could not be read.
ConfigDocument	document()	The parsed document.
Path	file()	The file that was read.

(package private) static ConfigLoadResult	loaded(Path file, ConfigDocument document, String fingerprint)
String	parserMessage()	Why the file could not be parsed: the parser's own message, naming the line and column.

file

public Path file()

The file that was read.

Returns:

the path as passed to load

state

public ConfigLoadResult.State state()

The outcome.

Returns:

the state

document

public ConfigDocument document()

The parsed document.

Returns:

the document when ConfigLoadResult.State.LOADED, otherwise null

fingerprint

public String fingerprint()

The SHA-256 of the bytes read, as 64 lower-case hex digits, so a later write can tell whether the file changed on disk since it was read.

Returns:

the fingerprint when ConfigLoadResult.State.LOADED, otherwise null

cause

public IOException cause()

Why the file could not be read.

Returns:

the I/O failure when ConfigLoadResult.State.UNREADABLE, otherwise null

parserMessage

public String parserMessage()

Why the file could not be parsed: the parser's own message, naming the line and column.

Returns:

the message when ConfigLoadResult.State.UNPARSEABLE, otherwise null

toString

public String toString()

Overrides:

toString in class Object
