Examples with RegularExpression org.apache.tools.ant.types.RegularExpression used on opensource projects

Example 1 with RegularExpression

use of org.apache.tools.ant.types.RegularExpression in project JikesRVM by JikesRVM.

the class SelectRegexTask method setPattern.

public void setPattern(final String pattern) {
    this.pattern = new RegularExpression();
    this.pattern.setPattern(pattern);
    this.patternLines = pattern.split(System.getProperty("line.separator")).length;
}

Example 2 with RegularExpression

use of org.apache.tools.ant.types.RegularExpression in project ant by apache.

the class LineContainsRegExp method 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

Example 3 with RegularExpression

use of org.apache.tools.ant.types.RegularExpression in project ant by apache.

the class FilenameSelector method isSelected.

/**
 * The heart of the matter. This is where the selector gets to decide
 * on the inclusion of a file in a particular fileset. Most of the work
 * for this selector is offloaded into SelectorUtils, a static class
 * that provides the same services for both FilenameSelector and
 * DirectoryScanner.
 *
 * @param basedir the base directory the scan is being done from
 * @param filename is the name of the file to check
 * @param file is a java.io.File object the selector can use
 * @return whether the file should be selected or not
