Interface ComparisonExpression

public interface ComparisonExpression extends Serializable

Interface implemented by expressions that perform a comparison
Method Summary
booleanconvertsUntypedToOther()
Determine whether untyped atomic values should be converted to the type of the other operand
AtomicComparergetAtomicComparer()
Get the AtomicComparer used to compare atomic values.
Expression[]getOperands()
Get the two operands of the comparison
intgetSingletonOperator()
Get the primitive (singleton) operator used: one of Token.FEQ, Token.FNE, Token.FLT, Token.FGT, Token.FLE, Token.FGE

Method Detail

convertsUntypedToOther

public 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.

getAtomicComparer

public AtomicComparer getAtomicComparer()
Get the AtomicComparer used to compare atomic values. This encapsulates any collation that is used

getOperands

public Expression[] getOperands()
Get the two operands of the comparison

getSingletonOperator

public int getSingletonOperator()
Get the primitive (singleton) operator used: one of Token.FEQ, Token.FNE, Token.FLT, Token.FGT, Token.FLE, Token.FGE
