Constructor Detail

BooleanUnaryExpr

public BooleanUnaryExpr(FilterConstants.UnaryLogicOperator operator,
                        BooleanExpr operand)

Create a new BooleanUnaryExpr.

Parameters:

operator - the operator

operand - the operand

Method Detail

isBooleanUnary

public boolean isBooleanUnary()

Description copied from interface: Expr

Check if this expression is a boolean unary expression.

Specified by:

isBooleanUnary in interface Expr

Returns:

if it is a unary boolean expression

asBooleanUnary

public java.util.Optional<BooleanUnaryExpr> asBooleanUnary()

Description copied from interface: Expr

Get this expression as a boolean unary expression

Specified by:

asBooleanUnary in interface Expr

Returns:

the expression or Optional.empty() if the type does not match

accept

public <T,X extends java.lang.Throwable> T accept(ExprVisitor<T,X> visitor)
                                           throws X extends java.lang.Throwable

Description copied from interface: Expr

Accepts visitor for this expression.

Specified by:

accept in interface Expr

Type Parameters:

T - the visitor's return type

X - the exception type the visitor may throw

Parameters:

visitor - the visitor

Returns:

the result of the visit

Throws:

X - if the visitor fails to visit this expression

X extends java.lang.Throwable

getOperand

public BooleanExpr getOperand()

Description copied from class: UnaryExpr

Get the operand

Overrides:

getOperand in class UnaryExpr<FilterConstants.UnaryLogicOperator>

Returns:

the operand
