Yes – poll<\/em> removes the first item in the list and returns it.
\nThis will then be evaluated in your if statement.<\/p>\n

On an unrelated note, it is worth mentioning that the size of edges<\/em> will obviously change on every loop since polling edges<\/em> reduces the element count by one. However, your for loop evaluates the size of edges<\/em> exactly once – on entry. A better way to implement this would be to use a while loop, for example.<\/p>\n

int i = 0;\n\nwhile(i<edges.size())\n{\n    if(edges.poll() == 5)\n    {\n        break;\n    }\n    i++\n}\n<\/code><\/pre>\n<\/p><\/div>\n
