The getBindings() method of a SimpleScriptContext class is used to return the bindings associated with the given scope in this ScriptContext where scope is passed as parameter.
Syntax:
Bindings getBindings(int scope)
Parameters: This method accepts a single parameter scope which is the scope in this ScriptContext.
Return value: This method returns associated Bindings and returns null if it has not been set.
Exceptions: This method throws following Exceptions:
- IllegalArgumentException: If no Bindings is defined for the specified scope value in ScriptContext of this type.
Below programs illustrate the SimpleScriptContext.getBindings() method:
Program 1:
// Java program to demonstrate// SimpleScriptContext.getBindings() method import javax.script.Bindings;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( "name1", "Value1", ScriptContext.ENGINE_SCOPE); simple.setAttribute( "name2", "Value2", ScriptContext.ENGINE_SCOPE); // get bindings using getBindings() Bindings bindings = simple.getBindings( ScriptContext.ENGINE_SCOPE); // print System.out.println("Bindings value for name1:" + bindings.get("name1")); System.out.println("Bindings value for name2:" + bindings.get("name2")); }} |
Output:
Bindings value for name1:Value1 Bindings value for name2:Value2
Program 2:
// Java program to demonstrate// SimpleScriptContext.getBindings() method import javax.script.Bindings;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.ENGINE_SCOPE); simple.setAttribute( "Team3", "Nepal", ScriptContext.ENGINE_SCOPE); // get bindings using getBindings() Bindings bindings = simple.getBindings( ScriptContext.ENGINE_SCOPE); // print System.out.println("Bindings value for Team1:" + bindings.get("Team1")); System.out.println("Bindings value for Team2:" + bindings.get("Team2")); System.out.println("Bindings value for Team3:" + bindings.get("Team3")); }} |
Output:
Bindings value for Team1:India Bindings value for Team2:Japan Bindings value for Team3:Nepal
