Evaluate()

virtual ExpressionResult ExpressionEvaluation::ExpressionEvaluationRequests::Evaluate ( const ExpressionTree &  expressionTree ) const

pure virtual

Evalutes the specified ExpressionTree /param expressionTree The ExpressionTree to be evaluated /return Returns the result of the expression evaluation.

EvaluateExpression()

virtual EvaluateStringOutcome ExpressionEvaluation::ExpressionEvaluationRequests::EvaluateExpression ( AZStd::string_view  expression ) const

pure virtual

Parses then Evaluates the specified Expression, and returns the result or parse error. /param expressionString The string to parse/evaluate /return Returns the result of the expression evaluation, or a Parsing Error.

ParseExpression()

virtual ParseOutcome ExpressionEvaluation::ExpressionEvaluationRequests::ParseExpression ( AZStd::string_view  expressionString ) const

pure virtual

Parses the expression into the returned ExpressionTree. /param expressionString The string to parse. /return Returns an Expression Tree, or a Parsing Error.

ParseExpressionInPlace()

virtual ParseInPlaceOutcome ExpressionEvaluation::ExpressionEvaluationRequests::ParseExpressionInPlace ( AZStd::string_view  expressionString, ExpressionTree &  expressionTree  ) const

pure virtual

Parses the expression into the supplied ExpressionTree. /param expressionString The string to parse. /param expressionTree The ExpressionTree that will contain the parsed tree on Success. /return Returns Success or a Parsing Error.

ParseRestrictedExpression()

virtual ParseOutcome ExpressionEvaluation::ExpressionEvaluationRequests::ParseRestrictedExpression ( const AZStd::unordered_set< ExpressionParserId > &  availableParsers, AZStd::string_view  expressionString  ) const

pure virtual

Parses the expression into the returned ExpressionTree using the specified list of parsers. /param availableParsers The list of parsers to use when parsing the expression. /param expressionString The string to parse. /return Returns an Expression Tree, or a Parsing Error.

ParseRestrictedExpressionInPlace()

virtual ParseInPlaceOutcome ExpressionEvaluation::ExpressionEvaluationRequests::ParseRestrictedExpressionInPlace ( const AZStd::unordered_set< ExpressionParserId > &  availableParsers, AZStd::string_view  expressionString, ExpressionTree &  expressionTree  ) const

pure virtual

Parses the expression into the supplied ExpressionTree using the specified list of parsers. /param availableParsers The list of parsers to use when parsing the expression. /param expressionString The string to parse. /param expressionTree The ExpressionTree that will contain the parsed tree on Success. /return Returns Success, or a Parsing Error.
