BoolConstantExpr

public BoolConstantExpr(boolean value)

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:
