A Statement
object represents a primitive statement
in which a single method is applied to a target and
a set of arguments - as in "a.setFoo(b)"
.
Note that where this example uses names
to denote the target and its argument, a statement
object does not require a name space and is constructed with
the values themselves.
The statement object associates the named method
with its environment as a simple set of values:
the target and an array of argument values.

Creates a new Statement
object with a target
,
methodName
and arguments
as per the parameters.
target | The target of this statement. |
---|---|
methodName | The methodName of this statement. |
arguments | The arguments of this statement. If null then an empty array will be used.

The execute method finds a method whose name is the same
as the methodName property, and invokes the method on
the target.
When the target's class defines many methods with the given name
the implementation should choose the most specific method using
the algorithm specified in the Java Language Specification
(15.11). The dynamic class of the target and arguments are used
in place of the compile-time type information and, like the
java.lang.reflect.Method
class itself, conversion between
primitive values and their associated wrapper classes is handled
internally.
The following method types are handled as special cases:
Expression
s rather than Statement
s
as they return a value.
java.util.List
interface may also be applied to array instances, mapping to
the static methods of the same name in the Array
class.
