foreach $value (values %hash) while(($key,$value)=each %hash) Perl有上述三个函数可对相关数组做运算:keys函数可取出相关变量的索引值,组成一纯量数组,注意这些由keys函数取出的索引值没有次序性;values函数可取出相关变量的元素值;each函数则会取出(索引、元素)对。使用者可视情况而用。 (d) References(...
Instead a compact form is used, which can only store values that are integers (signed and unsigned), strings or "undef" - references and floating point values are stringified. If you need to store multiple values or complex structures, you should serialise them, for example with "pack". ...
methods that return multiple valuesWhen a method returns more than one value, it checks the context and returns either a list of values or an ArrayRef.transaction-handling methodsWarning: the behaviour of the TRANSACTIONS commands when combined with pipelining is still under discussion, and you ...
While either approach will work, a developer would be better off using the first technique if multiple values need to be checked in order to avoid looping through the array multiple times. For a one-off check, though, this would not be an issue; both ways would be acceptable. ...
See also kubernetes_get_secret_values.sh to debug the actual values that got loaded. See also Sealed Secrets / External Secrets in my Kubernetes repo gcp_secrets_to_kubernetes_multipart.sh - creates a Kubernetes secret from multiple GCP secrets (used to put private.pem and public.pem into ...
The out_* vars return values, and so are pointers to where the returned values should be stored. out_capture, if non-null, requests that the innermost instance of the lexical is captured; out_name_sv is set to the innermost matched namesv or fake namesv; out_flags returns the flags ...
After the OAuth2 authentication is completed, an application can call this method to get any of the parameter values. For example, to get the realmId value, pass realmId in paramName. See the code snippet at the very bottom of the example linked below. Returns 1 for success, 0 for fail...
