Example 61 with DynamicObject

use of com.oracle.truffle.api.object.DynamicObject in project graal by oracle.

the class SLContext method createObject.

/**
 * Allocate an empty object. All new objects initially have no properties. Properties are added
 * when they are first stored, i.e., the store triggers a shape change of the object.
