SimpleScriptContext setBindings() method in Java with Examples
The setBindings() method of a SimpleScriptContext class is used to set a Bindings of attributes for the given scope where Bindings and scope are passed as parameters to the method. If the scope is ENGINE_SCOPE the given Bindings replaces the engineScope field. If the scope is GLOBAL_SCOPE the given Bindings replaces the globalScope field.
Syntax:
public void setBindings(Bindings bindings,
int scope)
Parameters: This method accepts two-parameters:
- bindings which is the Bindings of attributes to set and
- scope which is the scope in which to set the attribute.
Return value: This method returns nothing.
Exceptions: This method throws following Exceptions:
- NullPointerException: if the value of scope is ENGINE_SCOPE and the specified Bindings is null.
- IllegalArgumentException: if the scope is invalid.
Below programs illustrate the SimpleScriptContext.setBindings() method:
Program 1:
// Java program to demonstrate// SimpleScriptContext.setBindings() method  import javax.script.ScriptContext;import javax.script.SimpleBindings;import javax.script.SimpleScriptContext;  public class GFG {    public static void main(String[] args)    {          // create SimpleScriptContext object        SimpleScriptContext simple            = new SimpleScriptContext();          // create Bindings        SimpleBindings bindings            = new SimpleBindings();          // add some key-value to bindings        bindings.put("name1", "Value1");          // add bindings to SimpleScriptContext using        // setBindings() Method        simple.setBindings(            bindings,            ScriptContext.ENGINE_SCOPE);          // print        System.out.println(            "name1:"            + simple.getAttribute("name1"));    }} |
Output:
name1:Value1
Program 2:
// Java program to demonstrate// SimpleScriptContext.setBindings() method  import javax.script.ScriptContext;import javax.script.SimpleBindings;import javax.script.SimpleScriptContext;  public class GFG {    public static void main(String[] args)    {          // create SimpleScriptContext object        SimpleScriptContext simple            = new SimpleScriptContext();          // create Bindings        SimpleBindings bindings            = new SimpleBindings();          // add some key-value to bindings        bindings.put("Team1", "India");        bindings.put("Team2", "Japan");        bindings.put("Team3", "Nepal");          // add bindings to SimpleScriptContext using        // setBindings() Method        simple.setBindings(            bindings,            ScriptContext.ENGINE_SCOPE);          // print        System.out.println("Team1:"                           + simple.getAttribute("Team1"));        System.out.println("Team2:"                           + simple.getAttribute("Team2"));        System.out.println("Team3:"                           + simple.getAttribute("Team3"));    }} |
Output:
Team1:India Team2:Japan Team3:Nepal
