API: bytes ​

Source: io/bytes.ts

Provides utilities for converting and manipulating byte arrays, facilitating conversions between JavaScript arrays, Java arrays, text, and integers.

Usage ​

javascript
import { bytes } from "sdk/io"

console.log(bytes.textToByteArray("Hello World"));
console.log(bytes.byteArrayToText([72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100]));

Classes ​

Bytes ​

The Bytes class provides static methods for byte array operations, primarily
used to bridge data types between the JavaScript environment and native Java components.

Methods ​

toJavaBytes ​

  • toJavaBytes (bytes:any[]):any[]

    Converts a native JavaScript byte array (an array of numbers) to a Java byte array.
    This is used internally by the API layer to pass data to Java methods.

    @param bytes The JavaScript array of bytes (e.g., [104, 101, 108, 108, 111]).
    @returns A native Java byte array (internal representation).

toJavaScriptBytes ​

  • toJavaScriptBytes (internalBytes:any[]):any[]

    Converts a native Java byte array back to a JavaScript array of numbers.
    This is used internally by the API layer to retrieve data from Java methods.

    @param internalBytes The native Java byte array.
    @returns A JavaScript array containing the byte values (numbers).

textToByteArray ​

  • textToByteArray (text:string):any[]

    Converts a standard text string into a byte array using the default platform encoding.

    @param text The input text string.
    @returns A JavaScript array representing the bytes of the text.

byteArrayToText ​

  • byteArrayToText (data:any[]):string

    Converts a byte array back into a text string.

    @param data The JavaScript array of bytes.
    @returns The reconstructed text string.

intToByteArray ​

  • intToByteArray (value:number, byteOrder:"BIG_ENDIAN"|"LITTLE_ENDIAN"):any[]

    Converts a 32-bit integer value into a byte array, respecting the specified byte order.

    @param value The integer value to convert.
    @param byteOrder Specifies the byte ordering: "BIG_ENDIAN" (most significant byte first) or "LITTLE_ENDIAN" (least significant byte first).
    @returns A JavaScript array representing the 4-byte integer.

byteArrayToInt ​

  • byteArrayToInt (data:any[], byteOrder:"BIG_ENDIAN"|"LITTLE_ENDIAN"):number

    Converts a 4-byte array back into a 32-bit integer value, respecting the specified byte order.

    @param data The 4-byte array (JavaScript array of numbers).
    @param byteOrder Specifies the byte ordering used during conversion.
    @returns The reconstructed integer value.
