Detailed Description

YailObject is a marker interface for data types defined by YAIL. Currently, that is YailList and YailDictionary. Any new non-primitive data types should also implement YailObject.

Member Function Documentation

◆ getObject()

Object com.google.appinventor.components.runtime.util.YailObject< T >.getObject ( int index )

Get the object at the given index. The index is 0-based.

Parameters

index The index of the object to retrieve.

Returns: An object dependent on the implementation. The returned object should be coercible to another YAIL type.

Exceptions

IndexOutOfBoundsException if the index is less than zero or greater than or equal to the size() of the object.

Implemented in com.google.appinventor.components.runtime.util.YailList.

◆ isEmpty()

boolean com.google.appinventor.components.runtime.util.YailObject< T >.isEmpty ( )

Test whether the object is empty.

Returns: True if the object is empty, otherwise false.

◆ iterator()

Iterator<T> com.google.appinventor.components.runtime.util.YailObject< T >.iterator ( )

Returns an iterator over the elements in the YailObject. For YailList this may be any other YAIL type and for YailDictionary this is always YailList.

◆ size()

int com.google.appinventor.components.runtime.util.YailObject< T >.size ( )

Get the size of the object. The exact semantics depend on the object, but typically this should be the number of elements in the object. For lists, it is the length of the list and for dictionaries it is the size of the dictionary (number of pairs). Ideally this method should be constant time.

Returns: The size of the object.
