Method Details

execute

public abstract boolean execute(DynamicObject receiver)

Marks this object as shared.

Makes the object use a shared variant of the Shape, to allow safe usage of this object between threads. Objects with a shared Shape will not reuse storage locations for other fields. In combination with careful synchronization on writes, this can prevent reading out-of-thin-air values.

Throws:

UnsupportedOperationException - if the object is already shared.
