public class IDBIndex
extends java.lang.Object

IDBIndex interface of the IndexedDB API provides asynchronous access to an index in a database. An index is a kind of object store for looking up records in another object store, called the referenced object store. You use this interface to retrieve data.

IDBRequest	count(java.lang.Object query) A IDBRequest object on which subsequent events related to this operation are fired.

multiEntry

@JsProperty(name="multiEntry")
public boolean multiEntry()

A Boolean:

IDBIndex.multiEntry - MDN

objectStore

@JsProperty(name="objectStore")
 @Nonnull
public IDBObjectStore objectStore()

An IDBObjectStore.

unique

@JsProperty(name="unique")
public boolean unique()

A Boolean:

count

@Nonnull
public IDBRequest count(@Nullable
                                 java.lang.Object query)

A IDBRequest object on which subsequent events related to this operation are fired.

See Also:

IDBIndex.count - MDN

count

@Nonnull
public IDBRequest count()

A IDBRequest object on which subsequent events related to this operation are fired.

IDBIndex.count - MDN

get

@Nonnull
public IDBRequest get(@Nullable
                               java.lang.Object query)

If a value is found, then a structured clone of it is created and set as the result of the request object: this returns the record the key is associated with.

See Also:

IDBIndex.get - MDN

getAll

@Nonnull
public IDBRequest getAll(@Nullable
                                  java.lang.Object query,
                                  int count)

There is a performance cost associated with looking at the value property of a cursor, because the object is created lazily. To use a feature like getAll(), the browser has to create all the objects at once. If you are just interested in looking at each of the keys, for instance, it is more efficient to use a cursor. If you are trying to get an array of all the objects in an object store, though, you should use getAll().
