Represents a time zone specified by its offset from UTC.
Represents a date time value with a time zone, specified as a UTC offset
Common interface for components that can execute Neo4j queries.
A live session with a Neo4j instance. Sessions serve a role in transaction isolation and ordering semantics. Within a session, transactions run sequentially one after another. Session objects are not thread safe, if you want to run concurrent operations against the database, simply create multiple session objects.
Represents a transaction in the Neo4j database.
An authentication token is used to authenticate with a Neo4j instance. It usually contains a Principal, for instance a username, and one or more Credentials, for instance a password. See AuthTokens for available types of IAuthTokens.
Common interface for components that can provide auth tokens. For pre-baked implementations of this interface, see AuthTokenManagers.
The IBookmarkManager interface is intended for implementation by classes that provide convenient interfacing with Bookmarks in both the driver and user code.
The IBookmarkManagerFactory interface is intended for classes that construct instances of an IBookmarkManager implementation.
Provides a client certificate to the driver for mutual TLS.
The driver will call GetCertificateAsync() to get the latest certificate to use for new connections. The certificate is only used as a second factor for authentication authenticating the client. The DBMS user still needs to authenticate with an authentication token. All implementations of this interface must be thread-safe and non-blocking for caller threads. For instance, IO operations must not be done on the calling thread. Note that the work done in the methods of this interface count towards the connectionAcquisition. Should fetching the certificate be particularly slow, it might be necessary to increase the timeout.A query that can no longer be configured.
Represents the changes to the database made as a result of a query being run.
Provides information about the database that processed the query.
The IDriver instance maintains the connections with a Neo4j database, providing an access point via the IAsyncSession method.
Represents an Entity in the Neo4j graph database. An Entity could be a Node or a Relationship.
Exposes methods for configuring and executing a driver-level query.
This is a preview API, This API may change between minor revisions.
The GQL-status object as defined by the GQL standard. Returned by GqlStatusObjects
An input position refers to a specific character in a query.
The new ILogger differs from the legacy one in the message format the logging methods are accepting. In ILogger, each logging method accepts a message which specifies how the message would be formatted and one or many arguments that are used to replace placeholders in the message string. The following example shows a simplified version of how the ILogger is used in this driver:
logger.Info("Hello {0}, {1}", "Alice", "Bob");Represents a Node in the Neo4j graph database.
Representation for notifications found when executing a query. A notification can be visualized in a client pinpointing problems or other information about the query.
Marker interface for configuration objects of notifications.
Notification configuration allows the driver to specify which notification categories or severities to ignore when analyzing queries.
A Path is a directed sequence of relationships between two nodes. This generally represents a traversal or walk through a graph and maintains a direction separate from that of any relationships traversed. It is allowed to be of size 0, meaning there are no relationships in it. In this case, it contains only a single node which is both the start and the end of the path.
This describes the Plan that the database planner produced and used (or will use) to execute your query. This can be extremely helpful in understanding what a query is doing, and how to optimize it. For more details, see the Neo4j Manual. The plan for the query is a tree of plans - each sub-tree containing zero or more child plans. The query starts with the root plan. Each sub-plan is of a specific OperatorType, which describes what that part of the plan does - for instance, perform an index lookup or filter results. The Neo4j Manual contains a reference of the available operator types, and these may differ across Neo4j versions.
This is the same as a regular IPlan - except this plan has been executed, meaning it also contains detailed information about how much work each step of the plan incurred on the database.
A record contains ordered key and value pairs
A query that has been configured fully and now can only be executed.
Represents a Relationship in the Neo4j graph database.
Provides access to the result as an asynchronous stream of IRecords. The records in the result is lazily retrieved and can be visited only once in a sequential order.
The result summary of running a query. The result summary interface can be used to investigate details about the result, like the type of query run, how many and which kinds of updates have been executed, and query plan and profiling information if available. The result summary is only available after all result records have been consumed. Keeping the result summary around does not influence the lifecycle of any associated session and/or transaction.
This interface allows for the implementation of a client certificate provider that can be updated with new certificates.
Used by routing driver to resolve the initial address used to create the driver. Such resolution happens: 1) during the very first rediscovery when driver is created. 2) when all the known routers from the current routing table have failed and driver needs to fallback to the initial address.
Provides basic information of the server where the cypher query was executed.
Defines a method that negotiates a TLS connection.
