Bind API methods to metrics. Binding a method to a metric causes that metric's configured quota behaviors to apply to the method call.

Methods
public __construct( $data = NULL)
 

Constructor.

  • param array $data { Optional. Data for populating the Message object.
    @type string $selector
          Selects the methods to which this rule applies.
          Refer to [selector][google.api.DocumentationRule.selector] for syntax
          details.
    @type array|\Google\Protobuf\Internal\MapField $metric_costs
          Metrics to update when the selected methods are called, and the associated
          cost applied to each metric.
          The key of the map is the metric name, and the values are the amount
          increased for the metric against which the quota limits are defined.
          The value must not be negative.

public Google\Protobuf\Internal\Message::__debugInfo()
public Google\Protobuf\Internal\Message::byteSize()
 
  • ignore
public Google\Protobuf\Internal\Message::clear()
 

Clear all containing fields.

  • return null
public Google\Protobuf\Internal\Message::discardUnknownFields()
 

Clear all unknown fields previously parsed.

  • return null
public getMetricCosts()
 

Metrics to update when the selected methods are called, and the associated cost applied to each metric.

The key of the map is the metric name, and the values are the amount increased for the metric against which the quota limits are defined. The value must not be negative.

  • return string
public Google\Protobuf\Internal\Message::jsonByteSize( $options = 0)
 
  • ignore
public Google\Protobuf\Internal\Message::mergeFrom( $msg)
 

Merges the contents of the specified message into current message.

This method merges the contents of the specified message into the current message. Singular fields that are set in the specified message overwrite the corresponding fields in the current message. Repeated fields are appended. Map fields key-value pairs are overwritten. Singular/Oneof sub-messages are recursively merged. All overwritten sub-messages are deep-copied.

  • param object $msg Protobuf message to be merged from.
  • return null
public Google\Protobuf\Internal\Message::mergeFromJsonString( $data, $ignore_unknown = false)
 

Parses a json string to protobuf message.

This function takes a string in the json wire format, matching the encoding output by serializeToJsonString(). See mergeFrom() for merging behavior, if the field is already set in the specified message.

  • param string $data Json protobuf data.
  • param bool $ignore_unknown
  • return null
  • throws \Exception Invalid data.
public Google\Protobuf\Internal\Message::mergeFromString( $data)
 

Parses a protocol buffer contained in a string.

This function takes a string in the (non-human-readable) binary wire format, matching the encoding output by serializeToString(). See mergeFrom() for merging behavior, if the field is already set in the specified message.

  • param string $data Binary protobuf data.
  • return null
  • throws \Exception Invalid data.
public Google\Protobuf\Internal\Message::parseFromJsonStream( $input, $ignore_unknown)
 
  • ignore
public Google\Protobuf\Internal\Message::parseFromStream( $input)
 
  • ignore
public Google\Protobuf\Internal\Message::serializeToJsonStream( $output)
 
  • ignore
public Google\Protobuf\Internal\Message::serializeToJsonString( $options = 0)
 

Serialize the message to json string.

  • return string Serialized json protobuf data.
public Google\Protobuf\Internal\Message::serializeToStream( $output)
 
  • ignore
public Google\Protobuf\Internal\Message::serializeToString()
 

Serialize the message to string.

  • return string Serialized binary protobuf data.
public setMetricCosts( $var)
 

Metrics to update when the selected methods are called, and the associated cost applied to each metric.

The key of the map is the metric name, and the values are the amount increased for the metric against which the quota limits are defined. The value must not be negative.

Generated from protobuf field map<string, int64> metric_costs = 2;

  • param array|\Google\Protobuf\Internal\MapField $var
  • return $this
public setSelector( $var)
 

Selects the methods to which this rule applies.

Refer to [selector][google.api.DocumentationRule.selector] for syntax details.

Generated from protobuf field string selector = 1;

  • param string $var
  • return $this
Properties
protected $selector = ''
 

Selects the methods to which this rule applies.

Methods
protected Google\Protobuf\Internal\Message::hasOneof( $number)
protected Google\Protobuf\Internal\Message::mergeFromArray(array $array)
 

Populates the message from a user-supplied PHP array. Array keys correspond to Message properties and nested message properties.

Example:

$message->mergeFromArray([
    'name' => 'This is a message name',
    'interval' => [
         'startTime' => time() - 60,
         'endTime' => time(),
    ]
]);

This method will trigger an error if it is passed data that cannot be converted to the correct type. For example, a StringValue field must receive data that is either a string or a StringValue object.

  • param array $array An array containing message properties and values.
  • return null
protected Google\Protobuf\Internal\Message::mergeFromJsonArray( $array, $ignore_unknown)
protected Google\Protobuf\Internal\Message::readOneof( $number)
protected Google\Protobuf\Internal\Message::readWrapperValue( $member)
protected Google\Protobuf\Internal\Message::whichOneof( $oneof_name)
protected Google\Protobuf\Internal\Message::writeOneof( $number, $value)
protected Google\Protobuf\Internal\Message::writeWrapperValue( $member, $value)
Properties
private $metric_costs = NULL
 

Metrics to update when the selected methods are called, and the associated cost applied to each metric.

The key of the map is the metric name, and the values are the amount increased for the metric against which the quota limits are defined. The value must not be negative.
