public java.lang.Object invokeCustom(java.lang.String aCustomClassName,

                                     java.lang.Object[] aParams)
                              throws DIException

Invokes the specified method from the specified class. The method must be static. This method cannot invoke methods with null parameter values. All parameter values in the parameter object array MUST be non-null. If any value is null an Exception is thrown. If a user wants to invoke a method with a null parameter, he/she must use the other invokeCustom method. The usage of this method can be turned on/off. There is a property in the global.properties file called api.custom.method.invoke.on. If this property is set to true then this method can be invoked, otherwise an exception is thrown if this method is invoked. There is a restriction on the classes which can be directly invoked. The allowed classes are described in another property in the global.properties file called api.custom.method.invoke.allowed.classes. Only classes listed in this property can be directly invoked by this method. If a user tries to invoke a class which is not in this list then an exception is thrown.

Example: Suppose the following class is packaged in a jar file, which is then placed in the 'jars' folder of TDI:
public class MyClass {
public static Integer multiply(Integer a , Integer b){
return new Integer(a.intValue() * b.intValue());
}
}
Suppose the global.properties TDI configuration file contains the following lines:
api.custom.method.invoke.on=true
api.custom.method.invoke.allowed.classes=MyClass
Now we can do the following:

 //for Java use APIEngine.getLocalSession() to create new Session instance.
 
 var result = session.invokeCustom("MyClass", "multiply", new Array(3, 5));
 

Specified by:

invokeCustom in interface Session

Parameters:

aCustomClassName - The class containing the method to be invoked.

aMethodName - The name of the method to be invoked.

aParams - Array of parameters used by the invoked method.

Returns:

the result of dispatching the method represented with parameters aParams.

Throws:

DIException - If an error occurs while invoking the method.

                              throws DIException

Invokes the specified method from the specified class. The method must be static. This method is used when the user wants to invoke the specified method with a null parameter value. The main difference between these two invokeCustom methods is that when using this method the user MUST specify the parameters' type. The usage of this method can be turned on/off. There is a property in the global.properties file called api.custom.method.invoke.on. If this property is set to true then this method can be invoked, otherwise an exception is thrown if this method is invoked. There is a restriction on the classes which can be directly invoked. The allowed classes are described in another property in the global.properties file called api.custom.method.invoke.allowed.classes. Only classes listed in this property can be directly invoked by this method. If the user tries to invoke a class which is not in this list then an exception is thrown.

Example: Suppose the following class is packaged in a jar file, which is then placed in the 'jars' folder of TDI:
public class MyClass {
public static Integer multiply(Integer a , Integer b){
return new Integer(a.intValue() * b.intValue());
}
}
Suppose the global.properties TDI configuration file contains the following lines:
api.custom.method.invoke.on=true
api.custom.method.invoke.allowed.classes=MyClass
Now we can do the following:

 //for Java use APIEngine.getLocalSession() to create new Session instance.
 
 var result = session.invokeCustom("MyClass", "multiply", new Array(3, 5), new Array("java.lang.Integer", "java.lang.Integer"));
 

Specified by:

invokeCustom in interface Session

Parameters:

aCustomClassName - The class containing the method to be invoked.

Returns:

the result of dispatching the method represented with parameters' types aParamsClass.

Throws:

DIException - If an error occurs while invoking the method.
