Detailed Description

template<typename CharType>
struct TIOperatorEvaluationEnvironment< CharType >

Structures used for managing the evaluation environment for operators in an expression. This class manages the evaluation context to avoid templating the whole evaluation code on a context type

Member Function Documentation

ExecBinary()

template<typename CharType >

virtual FExpressionResult TIOperatorEvaluationEnvironment< CharType >::ExecBinary ( const TExpressionToken< CharType > &  Operator, const TExpressionToken< CharType > &  L, const TExpressionToken< CharType > &  R  ) const

pure virtual

Execute the specified token as a binary operator, if such an overload exists

Implemented in TOperatorEvaluationEnvironment< ContextType, CharType >.

ExecPostUnary()

template<typename CharType >

virtual FExpressionResult TIOperatorEvaluationEnvironment< CharType >::ExecPostUnary ( const TExpressionToken< CharType > &  Operator, const TExpressionToken< CharType > &  L  ) const

pure virtual

Execute the specified token as a unary operator, if such an overload exists

Implemented in TOperatorEvaluationEnvironment< ContextType, CharType >.

ExecPreUnary()

template<typename CharType >

virtual FExpressionResult TIOperatorEvaluationEnvironment< CharType >::ExecPreUnary ( const TExpressionToken< CharType > &  Operator, const TExpressionToken< CharType > &  R  ) const

pure virtual

Execute the specified token as a unary operator, if such an overload exists

Implemented in TOperatorEvaluationEnvironment< ContextType, CharType >.

ShouldShortCircuit()

template<typename CharType >

virtual bool TIOperatorEvaluationEnvironment< CharType >::ShouldShortCircuit ( const TExpressionToken< CharType > &  Operator, const TExpressionToken< CharType > &  L  ) const

pure virtual

Check whether we should short circuit the specified operator

Implemented in TOperatorEvaluationEnvironment< ContextType, CharType >.
