PropertiesloadFixture(String fixtureId)
Return Properties loaded from a fixture configuration file, or null if not found. 
File fixtureFile = getFixtureFile(getFixtureDirectory(), fixtureId);
if (fixtureFile.exists()) {
    return loadProperties(fixtureFile);
} else {
    printSkipNotice(fixtureId, fixtureFile);
    return null;
FileloadGradleResource(String fileName)
This can load a gradle resource, such as a .properties file. 
File junitFile = new File(fileName);
if (junitFile.exists()) {
    LOGGER.info("The file '" + junitFile.getAbsolutePath() + "' exists.");
} else {
    LOGGER.info("Problem loading Gradle resource: " + junitFile.getAbsolutePath());
return junitFile;
StringloadHeader(String fileName)
Read the header part of a properties file into a String. 
FileReader fr = null;
BufferedReader br = null;
try {
    fr = new FileReader(fileName);
    br = new BufferedReader(fr);
    String header = br.readLine();
    if (header != null && header.indexOf('#') == 0) {
        header = header.substring(1);
...
voidloadIncludes(String propertyName, boolean mandatory, File file, Properties configProps)
load Includes 
String includes = configProps.getProperty(propertyName);
if (includes != null) {
    StringTokenizer st = new StringTokenizer(includes, "\" ", true);
    if (st.countTokens() > 0) {
        String location;
        do {
            location = nextLocation(st);
            if (location != null) {

StringloadInputAsString(InputStream is)
Something really straight forward to read the content of the file. 
StringBuilder sb = new StringBuilder();
try {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8")); 
    String newline = System.getProperty("line.separator"); 
    String line = null;
    while ((line = reader.readLine()) != null) {
        sb.append(line + newline);
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        is.close();
    } catch (IOException e) {
        e.printStackTrace();
return sb.toString();
PropertiesloadInstallProps()
load Install Props 
try {
    Properties prop = new Properties();
    prop.load(new FileInputStream("caTissueInstall.properties"));
    return prop;
} catch (Exception e) {
    throw new RuntimeException("Error loading install properties file", e);
PropertiesloadJZ(File file)
load JZ 
Properties props = new Properties();
if (file.exists()) {
    try {
        FileReader reader = new FileReader(file);
        char[] buf = new char[1024];
        StringBuffer buffer = new StringBuffer();
        int read = 0;
        boolean isStarted = false;
...
SetloadKeys(String propertiesFileName, InputStream in)
load Keys 
Set<String> keys = new HashSet<String>();
Properties prop = new Properties();
if (in == null)
    throw new IOException("unable to get resource file " + propertiesFileName);
prop.load(in);
in.close();
for (Object key : prop.keySet()) {
    keys.add((String) key);
...
voidloadLibrary(String libFileName)
Attempts to load the given library from all paths in java.libary.path. 
boolean found = false;
String javaLibPath = System.getProperty("java.library.path");
for (String path : javaLibPath.split(":")) {
    File libFile = new File(path + File.separator + libFileName);
    if (libFile.exists()) {
        System.load(libFile.getPath());
        found = true;
        break;
...
voidloadLibrarySmart(String libraryName)
load Library Smart 
if (loadLibrary(libraryName))
    return;
String classPath = System.getProperty("java.class.path");
String stuff[] = classPath.split(":");
for (String s : stuff) {
    File f = new File(s);
    if (!f.isDirectory())
        continue;
