Class Summary

AndBOp	Imposes the constraint x AND y.
BindingConstraint
BNodeBOp	The BNODE()/BNODE(Literal) function as defined in SPARQL 1.1 Query Language for RDF.
CoalesceBOp	Coalesce BOp The COALESCE function form returns the RDF term value of the first expression that evaluates without error.
CompareBOp	Perform open-world value comparison operations per the SPARQL spec.
ComputedIN	"IN" and "NOT IN" operator based on testing of the enumerated value expressions.
ConcatBOp
ConditionalBind<E extends IV>	Operator causes a variable to be bound to the result of its evaluation as a side-effect unless the variable is already bound and the as-bound value does not compare as equals.
DatatypeBOp	Return the datatype of the literal argument.
DateBOp	A date expression involving a left IValueExpression operand.
DateTimeUtility
DigestBOp	A Digest expression involving a IValueExpression operand.
EBVBOp	Calculates the "effective boolean value" of an IValueExpression.
EncodeForURIBOp
FalseBOp	Always evaluates to false.
FuncBOp	Call one of the Sesame casting functions.
IfBOp	Conditional if BOp
InBinaryBOp	A constraint that a variable may only take on the bindings enumerated by some set.
InBOp	Abstract base class for "IN" IConstraint implementations.
InferenceBVE
InHashBOp	A constraint that a value expression which may only take on the bindings enumerated by some set of constants.
IriBOp	The IRI function, as defined in SPARQL 1.1 Query Language for RDF.
IsBNodeBOp	Imposes the constraint isBNode(x).
IsBoundBOp	Imposes the constraint bound(x) for the variable x.
IsInlineBOp	Imposes the constraint isInline(x).
IsLiteralBOp	Imposes the constraint isLiteral(x).
IsMaterializedBOp	Imposes the constraint isMaterialized(x).
IsNumericBOp	Imposes the constraint isLiteral(x).
IsURIBOp	Imposes the constraint isURI(x).
IVValueExpression<T extends IV>	A specialized IValueExpression that evaluates to an IV.
LangBOp	Return the language tag of the literal argument.
LangMatchesBOp	Implements the langMatches SPARQL operator.
LcaseBOp	http://www.w3.org/2005/xpath-functions#lower-case
MathBOp	A math expression involving a left and right IValueExpression operand.
MathUtility
NeedsMaterializationBOp	Attempts to run a constraint prior to materialization.
NotBOp	Imposes the constraint !x.
NumericBOp	A math expression involving a left and right IValueExpression operand.
OrBOp	Imposes the constraint x OR y.
ProjectedConstraint
RandBOp
Range	Represents a numerical range of IVs - a lower bound and an upper bound.
RangeBOp	Operator used to impose a key-range constraint on a variable on access path.
RegexBOp
ReplaceBOp
SameTermBOp	Compare two terms for exact equality.
SPARQLConstraint<X extends XSDBooleanIV>	BOpConstraint that wraps a EBVBOp, which itself computes the effective boolean value of an IValueExpression.
SparqlTypeErrorBOp	Always throws a SparqlTypeError.
StrAfterBOp
StrBeforeBOp
StrBOp	Convert the IV to a xsd:string.
StrcontainsBOp
StrdtBOp
StrendsBOp
StrlangBOp
StrlenBOp
StrstartsBOp
SubstrBOp	This function has an origin of ONE (1) not ZERO (0).
TrueBOp	Always evaluates to true.
TryBeforeMaterializationConstraint	This is useful when a solution can be filtered out before it goes through the materialization pipeline.
UcaseBOp
XSDBooleanIVValueExpression	Base class for RDF value expression BOps that happen to evaluate to an XSDBooleanIV.
XsdStrBOp	Convert the IV to a xsd:string.

Exception Summary

ContextNotAvailableException

This generally indicates a failure to propagate the context wrapper for the binding set to a new binding set during a copy (projection), bind (join), etc.
