Port of JDK's IO classes for cross-platform support, facilitating Java-style IO operations. Offers modules for buffer, charset, URI handling, and seamless integration with kotlinx-io and Okio.
A Kotlin Multiplatform (KMP) port of Java’s IO classes, bringing familiar IO operations to multiplatform projects—JVM, Android, iOS, macOS, Linux, Windows, Web, and beyond.
This library is organized into modular components for flexibility and clarity.
Note Direct file read/write APIs are not included. For file operations, use this library in combination with
kotlinx-ioorokio, which support stream conversions.
com.fleeksoft.io:io-core)Core buffers plus the main stream/reader implementations and extensions.
com.fleeksoft.io:io)Charset-aware reader adapter and InputStream extensions.
InputStreamReaderval byteArrayInputStream: ByteArrayInputStream = "...".byteInputStream(Charsets.UTF8)
inputStreamReader: InputStreamReader = inputStream.reader(Charsets.UTF8)
bufferReader: BufferedReader = inputStream.bufferedReader(Charsets.UTF8)
com.fleeksoft.io:uri)Multiplatform-safe version of java.net.URI.
