Method: Elasticsearch::API::Utils#__listify

Defined in:
lib/elasticsearch/api/utils.rb

#__listify(*list) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Create a “list” of values from arguments, ignoring nil values and encoding special characters.

Examples:

Create a list from array

__listify(['A','B']) # => 'A,B'

Create a list from arguments

__listify('A','B') # => 'A,B'

Escape values

__listify('foo','bar^bam') # => 'foo,bar%5Ebam'

Do not escape the values

__listify('foo','bar^bam', escape: false) # => 'foo,bar^bam'
