Java BooleanNode-class And Method Code Example

Here is an example of using the BooleanNode class in the Jackson JSON library for Java:

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.node.BooleanNode;

public class Example {
    public static void main(String[] args) {
        JsonNode booleanNode = BooleanNode.valueOf(true);
        System.out.println(booleanNode.asText()); // Outputs "true"

In this example, we create a new JsonNode object using the BooleanNode.valueOf(boolean) method, passing in true as the argument. This creates a new BooleanNode object that represents the true value. We then use the asText() method to retrieve the text representation of the node, which is "true".

You can also use the BooleanNode.getTrue() or BooleanNode.getFalse() method to get the singleton instances of BooleanNode representing the "true" or "false" values respectively.

JsonNode trueNode = BooleanNode.getTrue();
JsonNode falseNode = BooleanNode.getFalse();

You can also check the value of the node by calling .booleanValue()

boolean value = booleanNode.booleanValue();
