### Question:
Varnode { public boolean intersects(Varnode varnode) { if (spaceID != varnode.spaceID) { return false; } if (isConstant() || isUnique() || isHash()) { return offset == varnode.getOffset(); } long endOtherOffset = varnode.offset; if (varnode.size > 0) { endOtherOffset = varnode.offset + varnode.size - 1; } return rangeIntersects(varnode.offset, endOtherOffset); } Varnode(Address a, int sz);  Varnode(Address a, int sz, int symbolKey); int getSize(); int getSpace(); Address getAddress(); Address getPCAddress(); long getOffset(); long getWordOffset(); boolean isFree(); boolean contains(Address address); boolean intersects(Varnode varnode); boolean intersects(AddressSetView set); boolean isAddress(); boolean isRegister(); boolean isConstant(); boolean isUnique(); boolean isHash(); boolean isInput(); boolean isPersistant(); boolean isAddrTied(); boolean isUnaffected(); PcodeOp getDef(); Iterator<PcodeOp> getDescendants(); PcodeOp getLoneDescend(); HighVariable getHigh(); short getMergeGroup(); void buildXML(StringBuilder buf); static void buildXMLAddress(StringBuilder resBuf, Address addr, int size); static String buildXMLAddress(Address addr); static String buildXMLAddress(Varnode[] varnodes, int logicalsize); static void appendSpaceOffset(StringBuilder buf, Address addr); static Varnode readXML(XmlPullParser parser, PcodeFactory factory); void trim(); @Override String toString(); String toString(Language language); @Override boolean equals(Object o); @Override int hashCode(); static Address readXMLAddress(XmlElement el, AddressFactory addrFactory); static Address readXMLAddress(String localName, Attributes attr,
			AddressFactory addrFactory); static Address readXMLAddress(String addrstring, AddressFactory addrfactory,
			AddressSpace refSpace);  }### Answer:
@Test public void testRamIntersects() { for (int i = 0; i < RAM_NODES.length; i++) { assertTrue("Varnodes expected to intersect [" + i + "]", RAM_NODES[i].intersects(INTERSECTING_RAM_NODES[i])); } for (int i = 0; i < RAM_NODES.length; i++) { assertTrue("Varnodes expected to not intersect [" + i + "]", !RAM_NODES[i].intersects(NON_INTERSECTING_RAM_NODES[i])); } }
@Test public void testStackIntersects() { for (int i = 0; i < STACK_NODES.length; i++) { assertTrue("Varnodes expected to intersect [" + i + "]", STACK_NODES[i].intersects(INTERSECTING_STACK_NODES[i])); } for (int i = 0; i < STACK_NODES.length; i++) { assertTrue("Varnodes expected to not intersect [" + i + "]", !STACK_NODES[i].intersects(NON_INTERSECTING_STACK_NODES[i])); } }
