I am trying to do some socket programming in Groovy. I am using code found here as a template:
http://programmingitch.blogspot.com/2010/04/groovy-sockets-example.html
My problem is with the server code.
It reads in the input buffer from a reader using the reader.readLine() method. It turns out it's a BufferedReader.
A problem that I am having is: What if the input is more than one line?
I have been trying for a few hours to get this.
Neither reader.getText(), reader.readLines() nor reader.eachLine() worked.
I tried a few things like this:
def reader = input.newReader()
def cc = reader.eachLine {
println "Here is the next element: ${it}"
}
println "Done iterating"
and
def reader = input.newReader()
def iter = reader.iterator()
while ( iter.hasNext() ) {
println "Here is the next element: ${iter.next()}"
println "About to get next, do we have next? "
println "iter is a ${iter?.getClass()?.getName()}"
}
println "Done iterating"
and
def holdLine
while ( ( holdLine = reader.readLine() ) ) {
println "holdLine: ${holdLine}"
}
println "Done"
In each case, it reads each line, but it does not get to the line after the loop.
Maybe there is something obvious that I am missing and I am making a mistake only a noob would make, but why won't the code break out of the loop?
