ResourceGroovyMethods (Groovy 4.0.5)

org.codehaus.groovy.runtime.ResourceGroovyMethods

```
public class ResourceGroovyMethods
extends DefaultGroovyMethodsSupport
```
This class defines new groovy methods for Files, URLs, URIs which appear on normal JDK classes inside the Groovy environment. Static methods are used with the first parameter being the destination class, i.e. public static long size(File self) provides a size() method for File.
NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.

    Closure closure)
    
    Processes each descendant file in this directory and any sub-directories. Processing consists of potentially calling closure passing it the current file (which may be a normal file or subdirectory) and then if a subdirectory was encountered, recursively processing the subdirectory.
    The traversal can be adapted by providing various options in the options Map according to the following keys:
    
    type
    A FileType enum to determine if normal files or directories or both are processed
    
    preDir
    A Closure run before each directory is processed and optionally returning a FileVisitResult value which can be used to control subsequent processing.
    
    preRoot
    A boolean indicating that the 'preDir' closure should be applied at the root level
    
    postDir
    A Closure run after each directory is processed and optionally returning a FileVisitResult value which can be used to control subsequent processing. Particularly useful when strict depth-first traversal is required.
    
    postRoot
    A boolean indicating that the 'postDir' closure should be applied at the root level
    
    visitRoot
    A boolean indicating that the given closure should be applied for the root dir (not applicable if the 'type' is set to FileType.FILES)
    
    maxDepth
    The maximum number of directory levels when recursing (default is -1 which means infinite, set to 0 for no recursion)
    
    filter
    A filter to perform on traversed files/directories (using the DefaultGroovyMethods.isCase method). If set, only files/dirs which match are candidates for visiting.
    
    nameFilter
    A filter to perform on the name of traversed files/directories (using the DefaultGroovyMethods.isCase method). If set, only files/dirs which match are candidates for visiting. (Must not be set if 'filter' is set)
    
    excludeFilter
    A filter to perform on traversed files/directories (using the DefaultGroovyMethods.isCase method). If set, any candidates which match won't be visited.
    
    excludeNameFilter
    A filter to perform on the names of traversed files/directories (using the DefaultGroovyMethods.isCase method). If set, any candidates which match won't be visited. (Must not be set if 'excludeFilter' is set)
    
    sort
    A Closure which if set causes the files and subdirectories for each directory to be processed in sorted order. Note that even when processing only files, the order of visited subdirectories will be affected by this parameter.
    
    This example prints out file counts and size aggregates for groovy source files within a directory tree:
```
 def totalSize = 0
 def count = 0
 def sortByTypeThenName = { a, b ->
     a.isFile() != b.isFile() ? a.isFile() <=> b.isFile() : a.name <=> b.name
 }
 rootDir.traverse(
         type         : FILES,
         nameFilter   : ~/.*\.groovy/,
         preDir       : { if (it.name == '.svn') return SKIP_SUBTREE },
         postDir      : { println "Found $count files in $it.name totalling $totalSize bytes"
                         totalSize = 0; count = 0 },
         postRoot     : true
         sort         : sortByTypeThenName
 ) {it -> totalSize += it.size(); count++ }
 
```
