Examples with StringWriter java.io.StringWriter used on opensource projects

Example 51 with StringWriter

use of java.io.StringWriter in project hadoop by apache.

the class TestTextCommand method inputStreamToString.

private String inputStreamToString(InputStream stream) throws IOException {
    StringWriter writer = new StringWriter();
    IOUtils.copy(stream, writer);
    return writer.toString();
}

Example 52 with StringWriter

use of java.io.StringWriter in project hadoop by apache.

the class TestLog4Json method testNestedException.

@Test
public void testNestedException() throws Throwable {
    Exception e = new NoRouteToHostException("that box caught fire 3 years ago");
    Exception ioe = new IOException("Datacenter problems", e);
    ThrowableInformation ti = new ThrowableInformation(ioe);
    Log4Json l4j = new Log4Json();
    long timeStamp = Time.now();
    String outcome = l4j.toJson(new StringWriter(), "testNestedException", timeStamp, "INFO", "quoted\"", "new line\n and {}", ti).toString();
    println("testNestedException", outcome);
    ContainerNode rootNode = Log4Json.parse(outcome);
    assertEntryEquals(rootNode, Log4Json.LEVEL, "INFO");
    assertEntryEquals(rootNode, Log4Json.NAME, "testNestedException");
    assertEntryEquals(rootNode, Log4Json.TIME, timeStamp);
    assertEntryEquals(rootNode, Log4Json.EXCEPTION_CLASS, ioe.getClass().getName());
    JsonNode node = assertNodeContains(rootNode, Log4Json.STACK);
    assertTrue("Not an array: " + node, node.isArray());
    node = assertNodeContains(rootNode, Log4Json.DATE);
    assertTrue("Not a string: " + node, node.isTextual());
    //rather than try and make assertions about the format of the text
    //message equalling another ISO date, this test asserts that the hypen
    //and colon characters are in the string.
    String dateText = node.textValue();
    assertTrue("No '-' in " + dateText, dateText.contains("-"));
    assertTrue("No '-' in " + dateText, dateText.contains(":"));
