Interface ComparisonExpression

public interface ComparisonExpression extends Serializable

Interface implemented by expressions that perform a comparison

Method Summary
boolean	convertsUntypedToOther() Determine whether untyped atomic values should be converted to the type of the other operand
AtomicComparer	getAtomicComparer() Get the AtomicComparer used to compare atomic values.
Expression[]	getOperands() Get the two operands of the comparison
int	getSingletonOperator() Get the primitive (singleton) operator used: one of Token.FEQ, Token.FNE, Token.FLT, Token.FGT, Token.FLE, Token.FGE

Method Detail

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.

public AtomicComparer getAtomicComparer()

Get the AtomicComparer used to compare atomic values. This encapsulates any collation that is used

public Expression[] getOperands()

Get the two operands of the comparison

public int getSingletonOperator()

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