List of existsForNodes() Examples

Examples of existsForNodes()

org.neo4j.graphdb.index.IndexManager.existsForNodes()
Returns whether or not there exists a node index with the name {@code indexName}. Indexes are created when needed in calls to {@link #forNodes(String)} and {@link #forNodes(String,Map)}. @param indexName the name of the index to check. @return whether or not there exists a node index with the name{@code indexName}.
org.neo4j.rest.graphdb.index.RestIndexManager.existsForNodes()
