Example 1 with DataFormatMatcher

use of com.fasterxml.jackson.core.format.DataFormatMatcher in project jackson-core by FasterXML.

the class TestJsonFormatDetection method testSimpleValidObject.

public void testSimpleValidObject() throws Exception {
    JsonFactory jsonF = new JsonFactory();
    DataFormatDetector detector = new DataFormatDetector(jsonF);
    final String JSON = "{  \"field\" : true }";
    DataFormatMatcher matcher = detector.findFormat(new ByteArrayInputStream(JSON.getBytes("UTF-8")));
    // should have match
    assertTrue(matcher.hasMatch());
    assertEquals("JSON", matcher.getMatchedFormatName());
    assertSame(jsonF, matcher.getMatch());
    // no "certain" match with JSON, but solid:
    assertEquals(MatchStrength.SOLID_MATCH, matcher.getMatchStrength());
    // and thus:
    JsonParser jp = matcher.createParserWithMatch();
    assertToken(JsonToken.START_OBJECT, jp.nextToken());

    final String NON_JSON = "<root />";
    DataFormatMatcher matcher = detector.findFormat(new ByteArrayInputStream(NON_JSON.getBytes("UTF-8")));
    // should not have match
    assertFalse(matcher.hasMatch());
    // and thus:

    // also:
    assertNull(matcher.createParserWithMatch());
}

Example 3 with DataFormatMatcher

use of com.fasterxml.jackson.core.format.DataFormatMatcher in project jackson-core by FasterXML.

the class TestJsonFormatDetection method testSimpleValidString.

    JsonFactory jsonF = new JsonFactory();
    DataFormatDetector detector = new DataFormatDetector(jsonF);
    final String JSON = "\"JSON!\"";
    DataFormatMatcher matcher = detector.findFormat(new ByteArrayInputStream(JSON.getBytes("UTF-8")));
    // should have match
    assertTrue(matcher.hasMatch());
    assertEquals("JSON", matcher.getMatchedFormatName());

    JsonFactory jsonF = new JsonFactory();
    DataFormatDetector detector = new DataFormatDetector(jsonF);
    final String ARRAY_JSON = "[ 1, 2 ]";
    DataFormatMatcher matcher = detector.findFormat(new ByteArrayInputStream(ARRAY_JSON.getBytes("UTF-8")));
    // should have match
    assertTrue(matcher.hasMatch());
    assertEquals("JSON", matcher.getMatchedFormatName());
    assertSame(jsonF, matcher.getMatch());
    // no "certain" match with JSON, but solid:
    assertEquals(MatchStrength.SOLID_MATCH, matcher.getMatchStrength());
    // and thus:
