Prototype

public int available() throws IOException 

Source Link

Document

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.

Usage

From source file:net.krotscheck.util.ResourceUtilTest.java

/**
 * Assert that nonexistent files provide the expected response.
 *
 * @throws Exception Should not be thrown.
 *///w  ww. jav a2 s.  c o m
@Test
public void testGetDirectoryResource() throws Exception {
    String name = "/dir";
    InputStream stream = ResourceUtil.getResourceAsStream(name);
    Assert.assertFalse(stream.available() > 0);

    String content = ResourceUtil.getResourceAsString(name);
    Assert.assertEquals("", content);
}
