Files

Lightweight full-file I/O helpers.

Files is intended for simple whole-file operations where a stream object would only add lifecycle overhead. Use FileInputStream, FileOutputStream, FileReader or FileWriter when incremental processing is required.

import klyn.io

data as Byte[] = Byte[3]
data[0] = Byte(65)
data[1] = Byte(66)
data[2] = Byte(67)
Files.writeBytes("payload.bin", data)

Methods

Modifier and Type	Member	Description
public static	readBytesInto `readBytesInto(path as String, notnull buffer as Byte[], offset as Long = 0l, length as Long = -1l) as Long`	Reads bytes from a file directly into an existing byte buffer without allocating a stream object or an intermediate byte array.
public static	requireNoSymlinks `requireNoSymlinks(path as Path) as Void`	Refuses symlinks in a path or any ancestor, including dangling links.
public static	searchText `searchText(notnull path as Path, notnull pattern as String, options as SearchOptions = null) as ArrayList<SearchMatch>`	Collects text occurrences in one file or directory using Path's engine.
public static	searchText `searchText(notnull path as Path, notnull pattern as String, options as SearchOptions, notnull consumer as (SearchMatch) -> Boolean) as ULong`	Streams results through Path's engine.
public static native	writeBytes `writeBytes(path as String, content as Byte[]) as Void`	Writes bytes to a file, replacing existing content.
public static native	writeBytesWithPrefix `writeBytesWithPrefix(path as String, prefix as String, content as Byte[]) as Void`	Writes a text prefix followed by bytes to a file, replacing existing content.
public static	writeTextAtomic `writeTextAtomic(path as Path, content as String) as Void`	Publishes UTF-8 text by replacing a file atomically, without a partially written destination.
