# Interface: com.pnfsoftware.jeb.core.units.code.java.IJavaCall

Java AST interface to represent a method invocation. This interface is not used to represent new\-object or new\-array creation. 

 Example: 

```

 foo(0, 1, "bar")
 
```

## Method: isLambdaCall
- return type: `boolean`

Description: Determine whether the call represents a lambda implementation call.
return: true if this call is a lambda call

## Method: isStaticCall
- return type: `boolean`

Description: Determine whether the call is static.
return: true if this call is static

## Method: isSuperCall
- return type: `boolean`

Description: Determine if the call is to a super\-class method.
