### Question:
DirSyncControl extends AbstractControl implements RequestControl, ResponseControl { @Override public byte[] encode() { final ConstructedDEREncoder se = new ConstructedDEREncoder( UniversalDERTag.SEQ, new IntegerType(BigInteger.valueOf(getFlags())), new IntegerType(getMaxAttributeCount()), new OctetStringType(getCookie() != null ? getCookie() : EMPTY_COOKIE)); return se.encode(); } DirSyncControl();  DirSyncControl(final boolean critical);  DirSyncControl(final Flag[] f);  DirSyncControl(final Flag[] f, final boolean critical);  DirSyncControl(final Flag[] f, final int count);  DirSyncControl(final Flag[] f, final int count, final boolean critical);  DirSyncControl(final Flag[] f, final byte[] value, final boolean critical);  DirSyncControl(final Flag[] f, final byte[] value, final int count, final boolean critical); @Override boolean hasValue(); long getFlags(); void setFlags(final long l); int getMaxAttributeCount(); void setMaxAttributeCount(final int count); byte[] getCookie(); void setCookie(final byte[] value); @Override boolean equals(final Object o); @Override int hashCode(); @Override String toString(); @Override byte[] encode(); @Override void decode(final DERBuffer encoded); static final String OID; }### Answer:
@Test(groups = "control", dataProvider = "request-response") public void encode(final DERBuffer berValue, final DirSyncControl expected) throws Exception { Assert.assertEquals(expected.encode(), berValue.getRemainingBytes()); }
