List of utility methods to do JFileChooser Filter
boolean | accept(File f, Collection Determines whether this file is accepted by the specified collection of filters if (filters == null || filters.isEmpty()) return true; for (FileFilter filter : filters) if (filter.accept(f)) return true; return false; |
File | completeFileExtension(File file, FileFilter filter) complete File Extension if ((file != null) && (filter != null)) { if (filter instanceof FileNameExtensionFilter) { String[] exts = ((FileNameExtensionFilter) filter).getExtensions(); String fName = file.getName(); if ((exts != null) && (fName != null)) { int dotPos = fName.indexOf('.'); if ((exts.length == 1) && ((dotPos < 0) || (dotPos == (fName.length() - 1)))) { if (dotPos < 0) { ... |
FileFilter | createFileFilter(final String description, final String[] extensions) create File Filter return new FileFilter() { @Override public String getDescription() { return description; @Override public boolean accept(File f) { if (!f.canRead()) ... |
FileFilter | createFileFilter(final String description, String extension) Example usage: SwingUtil.createFileFilter("JEQL script (*.jql)", "jql") final String dotExt = extension.startsWith(".") ? extension : "." + extension; FileFilter ff = new FileFilter() { public String getDescription() { return description; public boolean accept(File f) { return f.isDirectory() || f.toString().toLowerCase().endsWith(dotExt); }; return ff; |
FileFilter | createFileFilter(final String ext, final String desc) create File Filter return createFileFilter(new String[] { ext }, desc); |
FileFilter | createFileFilter(final String filter) create File Filter return new FileFilter() { public boolean accept(File f) { String ext = ""; String path = f.getPath(); int idx = path.lastIndexOf('.'); if (idx > 0) { ext = path.substring(idx + 1).toLowerCase(); if (ext.equals(filter)) ... |
FileFilter | createFileFilter(final String filterName, final String... extensionPatterns) Creates file filter for files with specified extensions and filter name. return new FileFilter() { @Override public boolean accept(final File f) { if (f.isDirectory()) { return true; final String path = f.getAbsolutePath(); for (final String extension : extensionPatterns) { ... |
FileNameExtensionFilter | createFileFilter(String text, String[]... suffixes) create File Filter SortedSet<String> sortedSuffixes = new TreeSet<>(); if (suffixes != null) { for (String[] a : suffixes) { if (a != null) { for (String s : a) { if (s != null) { sortedSuffixes.add(s.toLowerCase()); if (!sortedSuffixes.isEmpty()) { StringBuilder buf = new StringBuilder(256); buf.append(text); boolean isFirst = true; for (String s : sortedSuffixes) { if (isFirst) { buf.append(" ("); isFirst = false; } else { buf.append("; "); buf.append("*."); buf.append(s); if (!isFirst) { buf.append((char) ')'); text = buf.toString(); return new FileNameExtensionFilter(text, sortedSuffixes.toArray(new String[sortedSuffixes.size()])); |
boolean | fileEndsInValidExtension(File file, FileNameExtensionFilter filter) file Ends In Valid Extension for (String ext : filter.getExtensions()) { if (file.toString().endsWith("." + ext) || (ext.equals(WILDCARD) && file.toString().matches(FILE_NAME_WITH_EXTENSION_REGEX))) { return true; return false; |
String | fileNameAutoExtend(FileFilter filter, File file) If the user does not input the extension specified by the file filter, automatically augment the file name with the specified extension. if (filter == null) return file.getAbsolutePath(); String description = filter.getDescription().toLowerCase(); String extension = getExtensionInLowerCase(file); String filename = file.getAbsolutePath(); if (extension != null) { if (!filter.accept(file)) { filename = file.getAbsolutePath().concat(".").concat(description); ... |
