Property	Type	Description
$client	Client
$name	string	The name of the Database

Public Methods

Method	Description
__construct ( string $name, Client $client )	Construct a database object
alterRetentionPolicy ( InfluxDB\Database\RetentionPolicy $retentionPolicy )
create ( InfluxDB\Database\RetentionPolicy $retentionPolicy = null, boolean $createIfNotExists = true ) : influxdb\ResultSet	Create this database
createRetentionPolicy ( InfluxDB\Database\RetentionPolicy $retentionPolicy ) : influxdb\ResultSet
drop ( )	Drop this database
exists ( ) : boolean
getClient ( ) : Client
getName ( ) : string
getQueryBuilder ( ) : InfluxDB\Query\Builder	Retrieve the query builder
listRetentionPolicies ( ) : array
query ( string $query, array $params = [] ) : influxdb\ResultSet	Query influxDB
writePayload ( string \| array $payload, string $precision = self::PRECISION_NANOSECONDS, string \| null $retentionPolicy = null ) : boolean	Write a payload into InfluxDB using the current driver. This method is similar to `writePoints()`, except it takes a string payload instead of an array of Points. This is useful in the following situations:
writePoints ( array $points, string $precision = self::PRECISION_NANOSECONDS, string \| null $retentionPolicy = null ) : boolean	Write points into InfluxDB using the current driver. This is the recommended method for inserting data into InfluxDB.

Method Details

__construct() public method

Construct a database object

public __construct ( string $name, Client $client )
$name	string
$client	Client

alterRetentionPolicy() public method

public alterRetentionPolicy ( InfluxDB\Database\RetentionPolicy $retentionPolicy )
$retentionPolicy	InfluxDB\Database\RetentionPolicy

create() public method

Create this database

public create ( InfluxDB\Database\RetentionPolicy $retentionPolicy = null, boolean $createIfNotExists = true ) : influxdb\ResultSet
$retentionPolicy	InfluxDB\Database\RetentionPolicy
$createIfNotExists	boolean	Only create the database if it does not yet exist
return	influxdb\ResultSet

createRetentionPolicy() public method

public createRetentionPolicy ( InfluxDB\Database\RetentionPolicy $retentionPolicy ) : influxdb\ResultSet
$retentionPolicy	InfluxDB\Database\RetentionPolicy
return	influxdb\ResultSet

drop() public method

Drop this database

public drop ( )

exists() public method

public exists ( ) : boolean
return	boolean

getClient() public method

public getClient ( ) : Client
return	Client

getName() public method

public getName ( ) : string
return	string

getQueryBuilder() public method

Retrieve the query builder

public getQueryBuilder ( ) : InfluxDB\Query\Builder
return	InfluxDB\Query\Builder

getRetentionPolicyQuery() protected method

protected getRetentionPolicyQuery ( string $method, InfluxDB\Database\RetentionPolicy $retentionPolicy ) : string
$method	string
$retentionPolicy	InfluxDB\Database\RetentionPolicy
return	string

listRetentionPolicies() public method

public listRetentionPolicies ( ) : array
return	array

query() public method

Query influxDB

public query ( string $query, array $params = [] ) : influxdb\ResultSet
$query	string
$params	array
return	influxdb\ResultSet

writePayload() public method

1) Performing unique queries that may not conform to the current Point standard. 2) Inserting very large set of points into a measurement where looping via array_map() actually hurts performance as the payload may be calculated in advance by caller.

public writePayload ( string \| array $payload, string $precision = self::PRECISION_NANOSECONDS, string \| null $retentionPolicy = null ) : boolean
$payload	string \| array	InfluxDB payload (Or array of payloads) that conform to the Line syntax.
$precision	string	The timestamp precision (defaults to nanoseconds).
$retentionPolicy	string \| null	Specifies an explicit retention policy to use when writing all points. If not set, the default retention period will be used. This is only applicable for the Guzzle driver. The UDP driver utilizes the endpoint configuration defined in the server's influxdb configuration file.
return	boolean

writePoints() public method

Write points into InfluxDB using the current driver. This is the recommended method for inserting data into InfluxDB.

public writePoints ( array $points, string $precision = self::PRECISION_NANOSECONDS, string \| null $retentionPolicy = null ) : boolean
$points	array	Array of Point objects
$precision	string	The timestamp precision (defaults to nanoseconds).
$retentionPolicy	string \| null	Specifies an explicit retention policy to use when writing all points. If not set, the default retention period will be used. This is only applicable for the Guzzle driver. The UDP driver utilizes the endpoint configuration defined in the server's influxdb configuration file.
return	boolean
