Metadata API for PubNub Unity SDK

This page describes the new Objects v2. To upgrade from Objects v1, refer to the migration guide.

Objects provides easy-to-use, serverless storage for user and channel data you need to build innovative, reliable, scalable applications. Use Objects to easily store metadata about your application users and channels, and their membership associations, without the need to stand up your own databases.

PubNub also triggers events when object data is set or removed from the database. Clients can receive these events in real time and update their front-end application accordingly.

Remove Channel Members

Description

Remove members from a Channel.

Method(s)

To Remove Channel Members you can use the following method(s) in the Unity V4 SDK:

1. pubnub.RemoveChannelMembers().Channel(string).Remove( List<PNChannelMembersRemove>).Include(PNChannelMembersInclude[]).Limit(int).Count(bool).Start(string).End(string).Sort(List<string>).Async()
   

   Parameter	Type	Required	Default	Description
   Remove	List	Optional		List of channels (as [PNChannelMembersRemove] to remove a membership for.
   Channel	string	Yes		Channel name.
   Include	PNChannelMembersInclude[]	Optional		List of additional/complex UUID attributes to include in response. Omit this parameter if you don't want to retrieve additional attributes. Available values: PNChannelMembersIncludeIncludeCustom,PNChannelMembersIncludeChannel,PNChannelMembersIncludeChannelCustom.
   Limit	int	Optional	100	Number of objects to return in response. Default is 100, which is also the maximum value.
   Count	bool	Optional	false	Request Count to be included in paginated response. By default, Count is omitted.
   Start	string	Optional	null	Previously-returned cursor bookmark for fetching the next page.
   End	string	Optional	null	Previously-returned cursor bookmark for fetching the previous page. Ignored if you also supply the start parameter.
   Filter	string	Optional	null	Expression used to filter the results. Only objects whose properties satisfy the given expression are returned. The filter language is defined here In addition to custom attributes, the expressions can refer to attributes on associated entities one level deep (that is, the association and its target entities).
   Sort	List	Optional	null	List of properties to sort by.

Basic Usage

PNChannelMembersRemove inputRm = new PNChannelMembersRemove();
inputRm.UUID = new PNChannelMembersUUID {
        ID = uuidMetadataid
    };;

Objects Filtering Language Definition

The filtering language for Objects is similar to the stream filtering language.

Note the following:

• Date/time properties, such as updated, must be compared to valid date/time strings formatted according to ISO 8601.
• Custom properties must have the same type as the value used in the expression; it is an error to compare a custom property of one type to a value of another type.
• Objects that do not have the referenced custom property at all are excluded regardless of the operator or value used in the expression. The null value can be used to filter out objects that do or do not have the referenced custom property.
• The LIKE operator supports wildcards denoted by the * character. A wildcard matches any sequence of arbitrary Unicode characters, including the empty sequence. The literal asterisk is matched when escaped using the backslash (\) character.
• Values used with LIKE must be properly encoded just like any other string value. Thus, in order to escape an asterisk, the raw value must contain \\*.
• The entire expression must be properly URL-encoded when used in the query string.

<expression>           ::= <and_expression> ( "||" <and_expression> )*
<and_expression>       ::= <binary_condition> ( "&&" <binary_condition> )*
<binary_condition>     ::= "!" <binary_condition> | "(" <expression> ")" | <relational_condition>
<relational_condition> ::= <property_path> <relational_operator> <value>
<property_path>        ::= <property_name> ( "." <property_name> )*
<property_name>        ::= <identifier> | "[" <string> "]"
<value>                ::= <string> | <number> | "true" | "false" | "null"

Tokens

<identifier>           ::=  <letter> | "$" | "_" ( <letter> | "$" | "_" | <digit> )*
<relational_operator>  ::= "==" | "!=" | "<=" | ">=" | "<" | ">" | "LIKE"
<string>               ::= <double_quote> ( "\" <double_quote> | "\" <special_char>
                            | "\" "u" <hex_digit> <hex_digit> <hex_digit> <hex_digit>
                            | <unicode_char> - <double_quote> - "\" )* <double_quote>
                            | "'" ( "\" "'" | "\" <special_char>
                            | "\" "u" <hex_digit> <hex_digit> <hex_digit> <hex_digit>
                            | <unicode_char> - "'" - "\" )* "'"
<number>               ::= ( "+" | "-" )? ( <digit> )* ( "." )? <digit> ( <digit> )*
                            ( "e" | "E" ( "+" | "-" )? <digit> ( <digit> )* )?
<letter>               ::= Unicode Letter (category; any kind of letter from any language)
<digit>                ::= "0" .. "9"
<hex_digit>            ::= <digit> | "A" .. "F"
<double_quote>         ::= the " character
<unicode_char>         ::= any character in the Unicode range from U+0020 to U+10FFFF inclusive
<special_char>         ::= "\" | "/" | "b" | "f" | "n" | "r" | "t"

Sample object filtering operations

The following simple expression returns results whose custom property named public is equal to Boolean true.

custom.public == true

The following date/time comparison returns results that were modified on or after August 31st, 2019 (UTC):

updated >= "2019-08-31T00:00:00Z"

The following compound expression returns results that don't have a description, but do have a non-empty custom label or description property:

description == null && (custom.label != "" || custom.description != "")

The following wildcard expression returns results whose name starts with the letter X:

name LIKE 'X*'

The following escaped wildcard expression returns results whose name contains an asterisk:

name LIKE '*\\**'
