Examples with ByteBuffer java.nio.ByteBuffer used on opensource projects

Example 6 with ByteBuffer

use of java.nio.ByteBuffer in project camel by apache.

the class NIOConverter method toByteBuffer.

@Converter
public static ByteBuffer toByteBuffer(String value, Exchange exchange) {
    ByteBuffer buf = ByteBuffer.allocate(value.length());
    byte[] bytes = null;
    if (exchange != null) {
        String charsetName = exchange.getProperty(Exchange.CHARSET_NAME, String.class);
        if (charsetName != null) {
            try {
                bytes = value.getBytes(charsetName);
            } catch (UnsupportedEncodingException e) {
                LOG.warn("Cannot convert the byte to String with the charset " + charsetName, e);
            }
        }
    }
    if (bytes == null) {
        bytes = value.getBytes();
    }
    buf.put(bytes);
    buf.flip();
    return buf;
}

Example 7 with ByteBuffer

use of java.nio.ByteBuffer in project camel by apache.

the class NIOConverterTest method testToByteArrayBigBuffer.

/**
     * Test if returned array size is only to limit of ByteBuffer.
     * 
     * If byteBuffer capacity is bigger that limit, we MUST return data only to the limit.
     */
public void testToByteArrayBigBuffer() {
    ByteBuffer bb = ByteBuffer.allocate(100);
    bb.put("Hello".getBytes());
    bb.flip();
    byte[] out = NIOConverter.toByteArray(bb);
    assertNotNull(out);
    assertEquals(5, out.length);
}

Example 8 with ByteBuffer

use of java.nio.ByteBuffer in project camel by apache.

the class NIOConverterTest method testToString.

public void testToString() throws Exception {
    ByteBuffer bb = ByteBuffer.wrap("Hello".getBytes());
    String out = NIOConverter.toString(bb, null);
    assertNotNull(out);
    assertEquals("Hello", out);
}

Example 9 with ByteBuffer

use of java.nio.ByteBuffer in project camel by apache.

the class NIOConverterTest method testToByteBufferInteger.

public void testToByteBufferInteger() {
    ByteBuffer bb = NIOConverter.toByteBuffer(Integer.valueOf("2"));
    assertNotNull(bb);
    assertEquals(2, bb.getInt());
}

Example 10 with ByteBuffer

use of java.nio.ByteBuffer in project camel by apache.

the class XmlConverterTest method testToStreamSourceByByteBuffer.

public void testToStreamSourceByByteBuffer() throws Exception {
    Exchange exchange = new DefaultExchange(context);
    XmlConverter conv = new XmlConverter();
    ByteBuffer bytes = context.getTypeConverter().convertTo(ByteBuffer.class, "<foo>bar</foo>");
    StreamSource out = conv.toStreamSource(bytes, exchange);
    assertNotNull(out);
    assertEquals("<foo>bar</foo>", conv.toString(out, null));
}
