discard-in-java

Arguments: object

If the argument is a remote reference to a Java object, the reference is discarded.

The following methods are defined:

• (object-list cons)
• (object (eql :flush))
• (object integer)
• (object (eql :query))
• (object (eql :all))

(object-list cons)

Arguments: (object-list cons)

The argument must be a list of object references. It is considerably more efficient to discard a block of objects in one operation.

(object (eql :flush))

Arguments: (object (eql :flush))

Discard all dead references to Java objects.

(object integer)

Arguments: (object integer)

Discard the specified number of dead references to Java objects.

(object (eql :query))

Arguments: (object (eql :query))

Return two values, the number of dead entries and the number of live entries in the object cache.

(object (eql :all))

Arguments: (object (eql :all))

Discard all objects in the object cache.
