Method Detail

get

public Object get(String name)

Description copied from interface: Loader

Enabled: How modules (and other things) get imported.

If this loader is called 'foo__uriGetter', then '' will expand to 'foo__uriGetter.get("name")'.

optUncall

public Object[] optUncall(Object obj)

See org.erights.e.elib.serial.BaseLoader#getOptWrappingUncall.

Returns:

:nullOk([any, String, any[]]); either null or a 3-element list of

• a receiver object whose reconstruction would receive the message
• a String, which is the name of the message to call
• a list of arguments, whose reconstruction are the actual arguments to the call.

toString

public String toString()

Description copied from class: Object

Suppressed: Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.
