Returns the byte array which this buffer is based on, if there is one.

Usage

From source file:Main.java

private static byte[] longToBytes(long paramLong) {
    ByteBuffer localByteBuffer = ByteBuffer.allocate(8);
    localByteBuffer.putLong(paramLong);//from w w w .  j  ava 2 s .  co  m
    return localByteBuffer.array();
}

From source file:com.google.step2.util.EncodingUtil.java

public static byte[] getUtf8Bytes(String s) {
    if (s == null) {
        return ArrayUtils.EMPTY_BYTE_ARRAY;
    }//from   w w  w.  ja v a2  s.c  o m
    ByteBuffer bb = UTF8.encode(s);
    return ArrayUtils.subarray(bb.array(), 0, bb.limit());
}

From source file:org.hawkular.metrics.core.api.AvailabilityType.java

public static AvailabilityType fromBytes(ByteBuffer bytes) {
    switch (bytes.array()[bytes.position()]) {
    case 0://from   w w  w  .j  av  a 2  s .c  o m
        return UP;
    case 1:
        return DOWN;
    case 2:
        return UNKNOWN;
    default:
        throw new IllegalArgumentException(bytes.array()[0] + " is not a recognized availability type");
    }
}

From source file:Main.java

public static final boolean startsWith(final ByteBuffer bb, final byte[] prefix) {
    return startsWith(bb.array(), 0, bb.limit(), prefix, 0, prefix.length);
}

From source file:Main.java

}

From source file:Main.java
