C# (CSharp) System.Text.RegularExpressions RegexWriter.RegexCodeFromRegexTreeの例

RegexCodeFromRegexTree() private method

The top level RegexCode generator. It does a depth-first walk through the tree and calls EmitFragment to emits code before and after each child of an interior node, and at each leaf. It runs two passes, first to count the size of the generated code, and second to generate the code. We should time it against the alternative, which is to just generate the code and grow the array as we go.
