groovy - 安全なストリングスライス

Question

250 文字以下の文字列が必要です。私はJavaの方法でそれをやっていましたが、これにはグルーヴィーなショートカットがあります:

def longString = "This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string.This is my really long string."
def shortString = "This is my really short string."

#ideal would be something like:
return longString[0..250]
#versus how i currently have it
#how can i simplify this one...
return shortString.size() < 250? shortString: shortString.substring(0,250) 

Answer 1

使用できますtake：

String shortString = longString.take( 250 )
