Google Cloud Platform environment queries - Class Google::Cloud::Env::Variables (v2.3.0)

Reference documentation and code samples for the Google Cloud Platform environment queries class Google::Cloud::Env::Variables.

Access to system environment variables.

This is a hashlike object that controls access to environment variable data. It supports temporarily changing the data source (i.e. swapping ::ENV out for a different set of data) for mocking.

  def 
  
 [] 
 ( 
 key 
 ) 
  
 - 
>  
 String 
 , 
  
 nil 
 

Fetch the given environment variable from the backing data.

  def 
  
 backing_data 
 () 
  
 - 
>  
 Hash 
 { 
 String 
 = 
> String 
 } 
 

The backing data is a hash or hash-like object that represents the environment variable data. This can either be the actual environment variables object (i.e. ENV) or a substitute hash used for mocking.

  def 
  
 backing_data= 
 ( 
 value 
 ) 
  
 - 
>  
 Hash 
 { 
 String 
 = 
> String 
 } 
 

The backing data is a hash or hash-like object that represents the environment variable data. This can either be the actual environment variables object (i.e. ENV) or a substitute hash used for mocking.

  def 
  
 get 
 ( 
 key 
 ) 
  
 - 
>  
 String 
 , 
  
 nil 
 

Fetch the given environment variable from the backing data.

  def 
  
 initialize 
 () 
  
 - 
>  
 Variables 
 

Create an enviroment variables access object. This is initially backed by the actual environment variables (i.e. ENV).

  def 
  
 with_backing_data 
 ( 
 temp_backing_data 
 ) 
 

Run the given block with the backing data replaced with the given hash. The original backing data is restored afterward. This is used for debugging/testing/mocking.
