public __construct( $data = NULL)
 

Constructor.

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

    Clear all containing fields.

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

    Clear all unknown fields previously parsed.

    • return
    public getDescription()
     

    An optional description of the expression. This is a longer text which
    describes the expression, e.g. when hovered over it in a UI.

    Generated from protobuf field string description = 3;

    • return string
    public getExpression()
     

    Textual representation of an expression in
    Common Expression Language syntax.

    The application context of the containing message determines which
    well-known feature set of CEL is supported.

    Generated from protobuf field string expression = 1;

    • return string
    public getLocation()
     

    An optional string indicating the location of the expression for error
    reporting, e.g. a file name and a position in the file.

    Generated from protobuf field string location = 4;

    • return string
    public getTitle()
     

    An optional title for the expression, i.e. a short string describing
    its purpose. This can be used e.g. in UIs which allow to enter the
    expression.

    Generated from protobuf field string title = 2;

    • return string
    public Google\Protobuf\Internal\Message::jsonByteSize()
     
    • 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.

    • return
    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.

    • return
    • 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.

    • return
    • throws Exception Invalid data.

    • ignore
    public Google\Protobuf\Internal\Message::serializeToJsonString()
     

    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 setDescription( $var)
     

    An optional description of the expression. This is a longer text which
    describes the expression, e.g. when hovered over it in a UI.

    Generated from protobuf field string description = 3;

    • return $this
    public setExpression( $var)
     

    Textual representation of an expression in
    Common Expression Language syntax.

    The application context of the containing message determines which
    well-known feature set of CEL is supported.

    Generated from protobuf field string expression = 1;

    • return $this
    public setLocation( $var)
     

    An optional string indicating the location of the expression for error
    reporting, e.g. a file name and a position in the file.

    Generated from protobuf field string location = 4;

    • return $this
    public setTitle( $var)
     

    An optional title for the expression, i.e. a short string describing
    its purpose. This can be used e.g. in UIs which allow to enter the
    expression.

    Generated from protobuf field string title = 2;

    • return $this
    Methods
    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.

    private static Google\Protobuf\Internal\Message::normalizeArrayElementsToMessageType( $value, $class)
     

    Tries to normalize the elements in $value into a provided protobuf
    wrapper type $class. If $value is any type other than array, we do
    not do any conversion, and instead rely on the existing protobuf
    type checking. If $value is an array, we process each element and
    try to convert it to an instance of $class.

      private static Google\Protobuf\Internal\Message::normalizeToMessageType( $value, $class)
       

      Tries to normalize $value into a provided protobuf wrapper type $class.

      If $value is any type other than an object, we attempt to construct an
      instance of $class and assign $value to it using the setValue method
      shared by all wrapper types.

      This method will raise an error if it receives a type that cannot be
      assigned to the wrapper type via setValue.
