Class EntryBindings

java.lang.Object

au.com.codeka.carrot.bindings.EntryBindings

All Implemented Interfaces:

Bindings, java.lang.Iterable<java.lang.Object>

public final class EntryBindings
extends java.lang.Object
implements Bindings, java.lang.Iterable<java.lang.Object>

Bindings for Map.Entry.

It provides access to key and value of an Entry like so

    {{ item.key }} -> {{ item.value }}
 

Note: strictly spoken this would not be necessary, because the reflection function resolution would do the same (by calling Map.Entry#getKey() and Map.Entry#getValue(). A dedicated Bindings class is, however, considered better design and certainly faster.
