makepattern

public static Pattern makepattern(String s)

A small helper function generating a regular expression pattern. The pattern generated is meant to define the begin of a comment line. When using this pattern, use the Pattern.search() method instead of match. The pattern holds essentially the following regular expression

 ^\s*\Q{s}\E
 

where {s} denotes parameter s and where \Q means: treat upcoming chars literally until reaching \E. In other words, meta regular expression characters like * and the like are not honoured.

Parameters:

s - null allowed

Returns:

null if s is null, otherwise proper RE pattern.

ignore

protected boolean ignore(String line)

A method checking whether a input line shall be ignored or not. The given line is expected to hold any character but newline terminators. Such a line is typically given using the readLine() method of a Reader class. A line is ignored if

1. being a comment line
2. empty

However, checks wheather a comment line are only executed if a comment pattern has been installed. Empty lines are removed if attribute skipempty has been set to true.

Parameters:

line - not null

Returns:

true if line to be ignored

stripws

public static final String stripws(String text)

A helper method to strip unwanted whitespace from an input text. This method is expected to be called on a input text consiting of multiple lines.

Parameters:

text -

Returns:

resolvecontlines

public static final String resolvecontlines(String text)

A helper function to resolve continuation lines.

Parameters:

text -

Returns:

tobufreader

public static final BufferedReader tobufreader(String text)

readLine

public String readLine()

Returns:

read

public String read()
