< p > Check the static fields of classes conveniently, the usage is < code class = "docutils literal notranslate" > < span class = "pre" > getstatic< / span > < span class = "pre" > class_name< / span > < span class = "pre" > field_name< / span > < / code > .< / p >
< p > Tip: if the static field is a complex class, you can even use < a class = "reference external" href = "https://en.wikipedia.org/wiki/OGNL" > < code class = "docutils literal notranslate" > < span class = "pre" > OGNL< / span > < / code > < / a > to traverse, filter and access the inner properties of this class.< / p >
< p > E.g. suppose < code class = "docutils literal notranslate" > < span class = "pre" > n< / span > < / code > is a < code class = "docutils literal notranslate" > < span class = "pre" > Map< / span > < / code > and its key is a < code class = "docutils literal notranslate" > < span class = "pre" > Enum< / span > < / code > , then you can achieve this if you want to pick the key with a specific < code class = "docutils literal notranslate" > < span class = "pre" > Enum< / span > < / code > value:< / p >
