public class ZipScanner

extends DirectoryScanner

ZipScanner accesses the pattern matching algorithm in DirectoryScanner, which are protected methods that can only be accessed by subclassing. This implementation of FileScanner defines getIncludedFiles to return only the Zip File which is being scanned, not the matching Zip entries. Arguably, it should return the matching entries, however this would complicate existing code which assumes that FileScanners return a set of file system files that can be accessed directly.

Field Detail

srcFile

protected java.io.File srcFile

The zip file which should be scanned.

Constructor Detail

ZipScanner

public ZipScanner()

Method Detail

setSrc

public void setSrc(java.io.File srcFile)

Sets the srcFile for scanning. This is the jar or zip file that is scanned for matching entries.

Parameters:

srcFile - the (non-null) zip file name for scanning

getIncludedFiles

public java.lang.String[] getIncludedFiles()

Returns the zip file itself, not the matching entries within the zip file. This keeps the uptodate test in the Zip task simple; otherwise we'd need to treat zip filesets specially.

Specified by:

getIncludedFiles in interface FileScanner

Overrides:

getIncludedFiles in class DirectoryScanner

Returns:

the source file from which entries will be extracted.

getIncludedDirectories

public java.lang.String[] getIncludedDirectories()

Returns an empty list of directories to create.

Specified by:

getIncludedDirectories in interface FileScanner

Overrides:

getIncludedDirectories in class DirectoryScanner

Returns:

the names of the directories which matched at least one of the include patterns and none of the exclude patterns.

init

public void init()

Initialize DirectoryScanner data structures.

match

public boolean match(java.lang.String path)

Matches a jar entry against the includes/excludes list, normalizing the path separator.

Parameters:

path - the (non-null) path name to test for inclusion

Returns:

true if the path should be included false otherwise.
