wildcard

问题 I have an issue with some JSON I'm parsing into a template. Essentially, I'm constructing a query via a simple web interface, pulling back data in JSON format, and controlling the data/template with Mustache. However, I'm unable to query values on nested objects in the JSON via the URL...so I think I need to resort to conditional statements using Handlebars. Is it possible to run a like or indexof style comparison in an handlebars block helper using wildcards? i.e. {{#if folderPath ==

问题 Why does the declaration look like this: default <U extends Comparable<? super U>> Comparator<T> thenComparing( Function<? super T, ? extends U> keyExtractor) I understand most of it. It makes sense that U can be anything as long as it's comparable to a superclass of itself, and thus also comparable to itself. But I don't get this part: Function<? super T, ? extends U> Why not just have: Function<? super T, U> Can't the U just parameterize to whatever the keyExtractor returns, and still

问题 Suppose I have a generic class Generic<A extends BaseType> . Is there a notable difference, as far as the Java Language Specification is concerned, between the following two type declarations? Generic<?> Generic<? extends BaseType> What about nested wildcards? List<Generic<?>> List<Generic<? extends BaseType>> Thinking about this, I would assume these to be equivalent. Generic specifies that the type parameter A has BaseType for an upper bound. Thus, the wildcard should always be

问题 I created Wildcard certificate to support my site domain and subdomains. The new certificate works for my subdomains (e.g www.mydomain.com , sub.mydomain.com) But when I try to get to mydomain.com I get certificate warning: "the certificate is only valid for *.mydomain.com" Is it a problem with my configuration or just the Wildcard certificate doesn't support it? 回答1: For supporting both example.com and subdomain.example.com the certificate needs to include both *.example.com and example.com

TypeError: not enough arguments for

问题 This question follows on from a question I asked previously and it regards understanding how to access config files correctly using Snakemake. I have a specific problem I need to address which I'll ask first and a general problem understanding how indexing works which I'll ask second. I'm using snakemake to run and ATAC-seq pipeline from Alignment/QC through to motif analysis.

问题 I want to apply data validation to reference numbers, to force the following layout (ideally uppercase only): XX_NNX-XX_NNN_NN-XXX X = Numbers N = Letters Ex: 12_AB1-23_ABC_AB-123 The following custom formula allows all of it except for numbers - is there any workaround for this? I don't want to use * since it allows for more characters than I want. =COUNTIF(A1,"??_???-??_???_??-???") 回答1: You can choose AND to add a condition to the function you have already written. e.g. following shall

问题 Background: I use Mysql and there are millions data, each line have twenty columns, we have some complex search and some column use fuzzy match, such as username like '%aaa%' , it can't use mysql index unless remove the first % , but we need fuzzy match to do search like Satckoverflow search, i also checked Mysql fulltext index , but it doesn't support complex search whthin one sql if using other index.
