Method Details

runGroovyCode

public static Object runGroovyCode(String pgm,
 Map<String,Object> args)

Executes the given Groovy code with the specified arguments and returns the result.

This method allows dynamic execution of Groovy code provided as a string. Variables can be passed to the Groovy script via a map of arguments, making them accessible within the script's context.

Parameters:

pgm - the Groovy code to execute, provided as a String

args - a Map<String, Object> containing variable names and their values to be passed into the Groovy script; may be null if no variables are needed

Returns:

the result of the Groovy script execution, which can be any Object returned by the script

Throws:

groovy.lang.GroovyRuntimeException - if an error occurs during compilation or execution of the Groovy code

IllegalArgumentException - if the pgm parameter is null or empty

• Example Usage:

  
   public static void main(String[] args) {
       String groovyCode = "return 'Hello, ' + name + '!'";
       Map<String, Object> arguments = new HashMap<>();
       arguments.put("name", "World");
  
       Object result = runGroovyCode(groovyCode, arguments);
       System.out.println(result); // Outputs: Hello, World!
   }
   

runGroovyCode

public static Object runGroovyCode(String pgm)

Executes the given Groovy code and returns the result.

This method allows dynamic execution of Groovy code provided as a string, without passing any variables into the script. It is a convenience method that calls runGroovyCode(String, Map) with a null arguments map.

Parameters:

pgm - the Groovy code to execute, provided as a String

Returns:

the result of the Groovy script execution, which can be any Object returned by the script

Throws:

groovy.lang.GroovyRuntimeException - if an error occurs during compilation or execution of the Groovy code

IllegalArgumentException - if the pgm parameter is null or empty

• Example Usage:

  
   public static void main(String[] args) {
       String groovyCode = "return 'Hello, World!'";
  
       Object result = runGroovyCode(groovyCode);
       System.out.println(result); // Outputs: Hello, World!
   }
