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

Usage

From source file:Main.java

public static byte[] floatsToBytes(float[] floats) {
    ByteBuffer byteBuffer = ByteBuffer.allocate(floats.length * 4);
    byteBuffer.asFloatBuffer().put(floats);
    return byteBuffer.array();
}

From source file:Main.java

public final static boolean equalsP(final ByteBuffer bb, final byte[] bytes) {
    return equals(bb.array(), bb.position(), bytes);
}

From source file:Main.java

public final static boolean equals(final ByteBuffer bb1, final ByteBuffer bb2) {
    final byte[] array1 = bb1.array();
    final byte[] array2 = bb2.array();
    final int end1 = bb1.limit();
    final int end2 = bb2.limit();
    return equals(array1, 0, end1, array2, 0, end2);
}
