public Object getHashEntriesIterator()

Implements org.graalvm.polyglot.proxy.ProxyHashMap.getHashEntriesIterator.

Doc from org.graalvm.polyglot.proxy.ProxyHashMap.getHashEntriesIterator.

Returns the hash entries iterator. The returned object must be interpreted as an iterator using the semantics of Context#asValue(Object) otherwise an IllegalStateException is thrown. The iterator elements must be interpreted as two elements array using the semantics of Context#asValue(Object).

Examples for valid return values are:

Examples for valid iterator elements are:

Doc from org.graalvm.polyglot.proxy.ProxyHashMap.hasHashEntry.

Returns true if the proxy object contains a mapping for the specified key, or else false. Every key which returns true for hasHashEntry(Value) must be included in the iterator returned by getHashEntriesIterator() to allow guest language to enumerate map entries.

Implements org.graalvm.polyglot.proxy.ProxyHashMap.putHashEntry.

Doc from org.graalvm.polyglot.proxy.ProxyHashMap.putHashEntry.

Associates the specified value with the specified key. If the mapping for the specified key does not exist then a new mapping is defined otherwise, an existing mapping is updated.

public boolean removeHashEntry(Value key)

Overrides default org.graalvm.polyglot.proxy.ProxyHashMap.removeHashEntry.

Doc from org.graalvm.polyglot.proxy.ProxyHashMap.removeHashEntry.

Removes the mapping for a given key. If the removal of existing mappings is not supported then an UnsupportedOperationException is thrown.

Returns:boolean

true when the mapping was removed, false when the mapping didn't exist.
