Examples with Buffer io.vertx.core.buffer.Buffer used on opensource projects

Example 71 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class BufferTest method testAppendBytes.

@Test
public void testAppendBytes() throws Exception {
    int bytesLen = 100;
    byte[] bytes = TestUtils.randomByteArray(bytesLen);
    Buffer b = Buffer.buffer();
    b.appendBytes(bytes);
    assertEquals(b.length(), bytes.length);
    assertTrue(TestUtils.byteArraysEqual(bytes, b.getBytes()));
    b.appendBytes(bytes);
    assertEquals(b.length(), 2 * bytes.length);
    assertNullPointerException(() -> b.appendBytes(null));
}

Example 72 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class BufferTest method testGetString.

@Test
public void testGetString() throws Exception {
    String str = TestUtils.randomAlphaString(100);
    // encode ascii as UTF-8 so one byte per char
    Buffer b = Buffer.buffer(str, "UTF-8");
    assertEquals(100, b.length());
    String substr = b.getString(10, 20);
    assertEquals(str.substring(10, 20), substr);
    substr = b.getString(10, 20, "UTF-8");
    assertEquals(str.substring(10, 20), substr);
}

Example 73 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class BufferTest method testAppendByte2.

@Test
public void testAppendByte2() throws Exception {
    int bytesLen = 100;
    Buffer b = Buffer.buffer(TestUtils.randomByteArray(bytesLen));
    b.setByte(b.length(), (byte) 9);
}

Example 74 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class BufferTest method testGetSetMedium.

private void testGetSetMedium(boolean isLE) throws Exception {
    int numInts = 100;
    Buffer b = Buffer.buffer(numInts * 3);
    for (int i = 0; i < numInts; i++) {
        if (isLE) {
            b.setMediumLE(i * 3, MEDIUM_MAX_VALUE + i);
        } else {
            b.setMedium(i * 3, MEDIUM_MAX_VALUE + i);
        }
    }
    for (int i = 0; i < numInts; i++) {
        if (isLE) {
            assertEquals((MEDIUM_MAX_VALUE + i - MEDIUM_MAX_VALUE), b.getMediumLE(i * 3));
        } else {
            assertEquals((MEDIUM_MAX_VALUE + i - MEDIUM_MAX_VALUE), b.getMedium(i * 3));
        }
    }
}

Example 75 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class BufferTest method testToString.

@Test
public void testToString() throws Exception {
    String str = TestUtils.randomUnicodeString(100);
    Buffer buff = Buffer.buffer(str);
    assertEquals(str, buff.toString());
//TODO toString with encoding
}
