java	Provides all default Java QL imports.

backEdge	Holds if `inp` is an input to `phi` along a back edge.
eqFlowCond	Gets a condition that tests whether `v` equals `e + delta`.
getArrayDef	Gets the definition of `v` provided that `v` is a non-null array with an explicit `ArrayCreationExpr` definition and that the definition does not go through a back edge.
guardControlsSsaRead	Holds if `guard` controls the position `controlled` with the value `testIsTrue`.
guardDirectlyControlsSsaRead	Holds if `guard` directly controls the position `controlled` with the value `testIsTrue`.
ssaRead	Gets an expression that equals `v - d`.
ssaUpdateStep	Holds if `v` is an `SsaExplicitUpdate` that equals `e + delta`.
valueFlowStep	Holds if `e1 + delta` equals `e2`.

ConstantBooleanExpr	An expression that always has the same boolean value.
ConstantIntegerExpr	An expression that always has the same integer value.
ConstantStringExpr	An expression that always has the same string value.
