TokenFilter

• java.lang.Object
  • BaseFilterReader

Fields Summary
private Vector	filters string filters
private org.apache.tools.ant.util.Tokenizer	tokenizer the tokenizer to use on the input stream
private String	delimOutput the output token termination
private String	line the current string token from the input stream
private int	linePos the position in the current string token

Constructors Summary
public TokenFilter() Constructor for "dummy" instances. see BaseFilterReader#BaseFilterReader() super();
public TokenFilter(Reader in) Creates a new filtered reader. param in A Reader object providing the underlying stream. Must not be null. super(in);

Methods Summary
public void	add(org.apache.tools.ant.filters.TokenFilter$Filter filter) Add an arbitrary filter param filter the filter to add filters.addElement(filter);
public void	add(org.apache.tools.ant.util.Tokenizer tokenizer) add an arbitrary tokenizer param tokenizer the tokenizer to all, only one allowed if (this.tokenizer != null) { throw new BuildException("Only one tokenizer allowed"); } this.tokenizer = tokenizer;
public void	addContainsRegex(org.apache.tools.ant.filters.TokenFilter$ContainsRegex filter) contains regex filter param filter the contains regex filter filters.addElement(filter);
public void	addContainsString(org.apache.tools.ant.filters.TokenFilter$ContainsString filter) contains string filter param filter the contains string filter filters.addElement(filter);
public void	addDeleteCharacters(org.apache.tools.ant.filters.TokenFilter$DeleteCharacters filter) delete chars param filter the delete characters filter filters.addElement(filter);
public void	addFileTokenizer(org.apache.tools.ant.filters.TokenFilter$FileTokenizer tokenizer) add a file tokenizer param tokenizer the file tokenizer add(tokenizer);
public void	addIgnoreBlank(org.apache.tools.ant.filters.TokenFilter$IgnoreBlank filter) ignore blank filter param filter the ignore blank filter filters.addElement(filter);
public void	addLineTokenizer(org.apache.tools.ant.util.LineTokenizer tokenizer) add a line tokenizer - this is the default. param tokenizer the line tokenizer add(tokenizer);
public void	addReplaceRegex(org.apache.tools.ant.filters.TokenFilter$ReplaceRegex filter) replace regex filter param filter the replace regex filter filters.addElement(filter);
public void	addReplaceString(org.apache.tools.ant.filters.TokenFilter$ReplaceString filter) replace string filter param filter the replace string filter filters.addElement(filter);
public void	addStringTokenizer(org.apache.tools.ant.filters.TokenFilter$StringTokenizer tokenizer) add a string tokenizer param tokenizer the string tokenizer add(tokenizer);
public void	addTrim(org.apache.tools.ant.filters.TokenFilter$Trim filter) trim filter param filter the trim filter filters.addElement(filter);
public final java.io.Reader	chain(java.io.Reader reader) Creates a new TokenFilter using the passed in Reader for instantiation. param reader A Reader object providing the underlying stream. return a new filter based on this configuration TokenFilter newFilter = new TokenFilter(reader); newFilter.filters = filters; newFilter.tokenizer = tokenizer; newFilter.delimOutput = delimOutput; newFilter.setProject(getProject()); return newFilter;
public static int	convertRegexOptions(java.lang.String flags) convert regex option flag characters to regex options g - Regexp.REPLACE_ALL i - Regexp.MATCH_CASE_INSENSITIVE m - Regexp.MATCH_MULTILINE s - Regexp.MATCH_SINGLELINE param flags the string containing the flags return the Regexp option bits if (flags == null) { return 0; } int options = 0; if (flags.indexOf('g") != -1) { options |= Regexp.REPLACE_ALL; } if (flags.indexOf('i") != -1) { options |= Regexp.MATCH_CASE_INSENSITIVE; } if (flags.indexOf('m") != -1) { options |= Regexp.MATCH_MULTILINE; } if (flags.indexOf('s") != -1) { options |= Regexp.MATCH_SINGLELINE; } return options;
public int	read() Returns the next character in the filtered stream, only including lines from the original stream which match all of the specified regular expressions. return the next character in the resulting stream, or -1 if the end of the resulting stream has been reached exception IOException if the underlying stream throws an IOException during reading if (tokenizer == null) { tokenizer = new LineTokenizer(); } while (line == null || line.length() == 0) { line = tokenizer.getToken(in); if (line == null) { return -1; } for (Enumeration e = filters.elements(); e.hasMoreElements();) { Filter filter = (Filter) e.nextElement(); line = filter.filter(line); if (line == null) { break; } } linePos = 0; if (line != null) { if (tokenizer.getPostToken().length() != 0) { if (delimOutput != null) { line = line + delimOutput; } else { line = line + tokenizer.getPostToken(); } } } } int ch = line.charAt(linePos); linePos++; if (linePos == line.length()) { line = null; } return ch;
public static java.lang.String	resolveBackSlash(java.lang.String input) xml does not do "c" like interpretation of strings. i.e. \n\r\t etc. this method processes \n, \r, \t, \f, \\ also subs \s -> " \n\r\t\f" a trailing '\' will be ignored param input raw string with possible embedded '\'s return converted string return StringUtils.resolveBackSlash(input);
public void	setDelimOutput(java.lang.String delimOutput) set the output delimiter. param delimOutput replaces the delim string returned by the tokenizer, if present. this.delimOutput = resolveBackSlash(delimOutput);
