public DynamicObject getMethodPropertySource(String methodName,
                                             DynEnv env)

Description copied from class: DynamicObject

ALERT: this is some-what weired method but it helps to merge same named properties and methods

Overrides:

getDynamicValue

public Object getDynamicValue(String name,
                              DynEnv env)

Description copied from class: DynamicObject

Returns the `key' field or Defs.NOT_FOUND if `name' does not exist. Returns `FUNCTION_MARK' if `name' represent a function that can be invoke via execDynamicMethod. Note that returned `null' indicates that value is present but set to null.

Overrides:

getDynamicValue in class DynamicObject

setDynamicValue

public int setDynamicValue(String name,
                           Object value,
                           DynEnv env)

Description copied from class: DynamicObject

Set field `name' to `value'. Use `env' to unwrap `value' to a particular type or store it as is

Overrides:

setDynamicValue in class DynamicObject

Returns:

SETD_NOT_FOUND if fied `name' is absent, SETD_IGNORE if field exist but set is ignored SETD_OK if set opeartion was ok
