Method Detail
-
getAtomicComparer
AtomicComparer getAtomicComparer()
Get the AtomicComparer used to compare atomic values. This encapsulates any collation that is used
-
getSingletonOperator
int getSingletonOperator()
Get the primitive (singleton) operator used: one of Token.FEQ, Token.FNE, Token.FLT, Token.FGT, Token.FLE, Token.FGE
-
getOperands
Expression[] getOperands()
Get the two operands of the comparison
-
convertsUntypedToOther
boolean convertsUntypedToOther()
Determine whether untyped atomic values should be converted to the type of the other operand- Returns:
- true if untyped values should be converted to the type of the other operand, false if they should be converted to strings.
