### ContainsRegexpSelector

    public ContainsRegexpSelector()

  Creates a new `ContainsRegexpSelector` instance.

Method Detail

### toString

    public java.lang.String toString()

  Description copied from class: `DataType`
  Basic DataType toString().

  Overrides:
    `toString` in class `DataType`
  Returns:
    a string describing this object

### setExpression

    public void setExpression(java.lang.String theexpression)

  The regular expression used to search the file.

  Parameters:
    `theexpression` - this must match a line in the file to be selected.

### setCaseSensitive

    public void setCaseSensitive(boolean b)

  Whether to ignore case or not.

  Parameters:
    `b` - if false, ignore case.
  Since:
    Ant 1.8.2

### setMultiLine

    public void setMultiLine(boolean b)

    `b` - the value to set.
  Since:
    Ant 1.8.2

### setSingleLine

    public void setSingleLine(boolean b)

  Whether to treat input as singleline ('.' matches newline). Corresponds to java.util.regex.Pattern.DOTALL.

  Parameters:
    `b` - the value to set.
  Since:
    Ant 1.8.2

### setParameters

    public void setParameters(Parameter[] parameters)

  When using this as a custom selector, this method will be called. It translates each parameter into the appropriate setXXX() call.

  Specified by:
    `setParameters` in interface `Parameterizable`
  Overrides:

                              java.lang.String filename,
                              java.io.File file)

  Tests a regular expression against each line of text in the file.

  Specified by:
    `isSelected` in interface `FileSelector`
  Specified by:
    `isSelected` in class `BaseExtendSelector`
  Parameters:
    `basedir` - the base directory the scan is being done from
