public BoolAndExpr(BooleanExpression lhs,
                   BooleanExpression rhs)

Method Detail

substitute

public BooleanExpression substitute(Substitution substitutions)

Description copied from interface: Expression

Substitutes variables using the given function.

Specified by:

substitute in interface BooleanExpression

Specified by:

substitute in interface Expression

Parameters:

substitutions - a function mapping variable expressions to their replacement expressions

Returns:

the expression after substitution

evaluate

public java.lang.Boolean evaluate(Substitution substitutions)

Description copied from interface: Expression

Evaluates the expression after substituting contained variables.

Specified by:

evaluate in interface BooleanExpression

Specified by:

evaluate in interface Expression

Parameters:

substitutions - a function mapping variables to expressions that can be evaluated

Returns:

the result of evaluation

evaluateLazy

public LazyBoolEvaluationResult evaluateLazy(Substitution substitutions)

Description copied from interface: BooleanExpression

Evaluates the result of this expression (with the given substitutions) concurrently in the background.
The result can be retrieved by calling getResult() on the return value.

Specified by:

evaluateLazy in interface BooleanExpression

forEachChild

public void forEachChild(java.util.function.Consumer<Expression> action)

Description copied from interface: Expression

Calls action on every (direct) child of this expression. For example, for a GroupOpExpr, this would call action on the left- and right-hand-side and then return.

Specified by:

forEachChild in interface Expression

getLhs

public BooleanExpression getLhs()

Retrieves the Boolean expression on the left hand side of this Boolean AND.

getRhs

public BooleanExpression getRhs()

Retrieves the Boolean expression on the right hand side of this Boolean AND.
