SimpleScriptContext getAttributesScope() method in Java with Examples

The getAttributesScope() method of a SimpleScriptContext class is used to return the scope in which an attribute is defined and the name of attribute is passed as parameter.

Syntax:

public int getAttributesScope(String name)

Parameters: This method accepts a single parameter name which is the Name of the attribute.

Return value: This method returns lowest scope and returns -1 if no attribute with the given name is defined in any scope.

Exceptions: This method throws following Exceptions:

• NullPointerException if the name is null.
• IllegalArgumentException if the name is empty.

Below programs illustrate the SimpleScriptContext.getAttributesScope() method:
Program 1:

// Java program to demonstrate
// SimpleScriptContext.getAttributesScope() method

import javax.script.ScriptContext;
import javax.script.SimpleScriptContext;

public class GFG {
    public static void main(String[] args)
    {

        // create SimpleScriptContext object
        SimpleScriptContext simple
            = new SimpleScriptContext();

        // add some attribute
        simple.setAttribute(
            "name",
            "Value",
            ScriptContext.ENGINE_SCOPE);

        // get scope using getAttributesScope()
        int scope = simple.getAttributesScope("name");

        // print
        System.out.println("Scope :" + scope);
    }
}

Output:

Scope :100

Program 2:

// Java program to demonstrate
// SimpleScriptContext.getAttributesScope() method

import javax.script.ScriptContext;
import javax.script.SimpleScriptContext;

public class GFG {
    public static void main(String[] args)
    {

        // create SimpleScriptContext object
        SimpleScriptContext simple
            = new SimpleScriptContext();

        // add some attribute
        simple.setAttribute(
            "Team1",
            "India",
            ScriptContext.ENGINE_SCOPE);
        simple.setAttribute(
            "Team2",
            "Japan",
            ScriptContext.GLOBAL_SCOPE);
        simple.setAttribute(
            "Team3",
            "Nepal",
            ScriptContext.GLOBAL_SCOPE);

        // get scope using getAttributesScope()
        int scope1
            = simple.getAttributesScope("Team1");
        int scope2
            = simple.getAttributesScope("Team2");
        int scope3
            = simple.getAttributesScope("Team3");

        // print scopes of different teams
        System.out.println("Scope for Team1: "
                           + scope1);
        System.out.println("Scope for Team2: "
                           + scope2);
        System.out.println("Scope for Team3: "
                           + scope3);
    }
}

Output:

Scope for Team1: 100
Scope for Team2: -1
Scope for Team3: -1
