getMember

public Object getMember(String name)

Description copied from interface: ObjectLike

Raw-value accessor — returns the stored data value, or null for accessor descriptors (which have no extractable raw value). Internal map / Java-interop callers (toMap, Map.get, jsEntries) and subclass super.getMember(name) chains use this.

For JS-semantic reads that must invoke an accessor's getter, use ObjectLike.getMember(String, Object, CoreContext) instead.

Specified by:

getMember in interface ObjectLike

getPropertyOrNotFound

public Object getPropertyOrNotFound(String name)

Description copied from interface: ExternalAccess

ExternalAccess.getProperty(java.lang.String) for a caller that treats "no such property" as undefined rather than an error. The engine's own implementation answers with an internal not-found marker instead of throwing; the default below keeps every other implementation working unchanged, since the caller catches either way. Overriding it is an optimisation available inside the engine, not something an external implementor needs to do.

 Object value)
