Class JsBinary

java.lang.Object
jsonvalues.JsPrimitive
jsonvalues.JsBinary
All Implemented Interfaces:
JsValue
public final class JsBinary extends JsPrimitive
Represents an array of bytes in a JSON-like data structure. The purpose of the JsBinary class is to allow the inclusion of binary data within JSON-like objects, even though binary data is not part of the JSON specification. This class provides a means to serialize binary data into a string using the Base64 encoding scheme, making it compatible with JSON-like structures.

Binary data is often encountered in various data formats, and while JSON itself does not support binary data, the JsBinary class serves as a custom solution for embedding binary content within JSON-like objects.

When serialized to a JSON string, a JsBinary object is represented as a string containing the Base64-encoded binary data. Consequently, a JsBinary object and a JsStr object created from the Base64-encoded string are considered equal if the encoded content matches.

Here is an example of how to use JsBinary: 


 // Create a byte array containing binary data (e.g., image bytes)
 byte[] bytes = "foo".getBytes();

 // Encode the binary data as a Base64 string
 String base64 = Base64.getEncoder().encodeToString(bytes);

 // Create a JsBinary object from the byte array
 JsBinary binary = JsBinary.of(bytes);

 // Create a JsStr object from the Base64-encoded string
 JsStr strFromBase64 = JsStr.of(base64);

 // Check if the JsBinary and JsStr objects are considered equal
 boolean areEqual = binary.equals(strFromBase64); // true

It's important to note that while JsBinary is a useful tool for representing binary data in JSON-like structures, it is not part of the JSON standard. Its purpose is to provide a means of encoding binary data within a format that can coexist with JSON-like data structures.
