Represents a lambda expression that can be invoked. This class is thread safe.

Invoke the expression with the given parameters values.

Order of parameters must be the same of the parameters used during parse (DeclaredParameters).

Generate the given delegate by compiling the lambda expression.

The delegate to generate. Delegate parameters must match the one defined when creating the expression, see UsedParameters.

Generate a lambda expression.

The lambda expression. The delegate to generate. Delegate parameters must match the one defined when creating the expression, see UsedParameters.

Gets the parameters actually used in the expression parsed.

The used parameters.

Gets the parameters actually used in the expression parsed.

The used parameters.

Gets the parameters declared when parsing the expression.

The declared parameters.

Class used to parse and compile a text expression into an Expression or a Delegate that can be invoked. Expression are written using a subset of C# syntax. Only get properties, Parse and Eval methods are thread safe.

Creates a new Interpreter using InterpreterOptions.Default.

Creates a new Interpreter using the specified options.

Allows to enable/disable assignment operators. For security when expression are generated by the users is more safe to disable assignment operators.

Enable reflection expression (like x.GetType().GetMethod() or typeof(double).Assembly) by removing the DisableReflectionVisitor.

Allow the specified function delegate to be called from a parsed expression.

Allow the specified variable to be used in a parsed expression.

Allow the specified variable to be used in a parsed expression.

Allow the specified Expression to be used in a parsed expression. Basically add the specified expression as a known identifier.

Allow the specified list of identifiers to be used in a parsed expression. Basically add the specified expressions as a known identifier.

Allow the specified identifier to be used in a parsed expression. Basically add the specified expression as a known identifier.

Allow the specified type to be used inside an expression. The type will be available using its name. If the type contains method extensions methods they will be available inside expressions.

Allow the specified type to be used inside an expression. See Reference(Type, string) method.

Allow the specified type to be used inside an expression by using a custom alias. If the type contains extensions methods they will be available inside expressions.

Public name that must be used in the expression.

Allow the specified type to be used inside an expression by using a custom alias. If the type contains extensions methods they will be available inside expressions.

Parse a text expression and returns a Lambda class that can be used to invoke it.

Expression statement

Parse a text expression and returns a Lambda class that can be used to invoke it. If the expression cannot be converted to the type specified in the expressionType parameter an exception is throw.

Expression statement The expected return type. Use void or object type if there isn't an expected return type.

Parse a text expression and convert it into a delegate.

Delegate to use Expression statement Names of the parameters. If not specified the parameters names defined inside the delegate are used.

Parse a text expression and convert it into a lambda expression.

Delegate to use Expression statement Names of the parameters. If not specified the parameters names defined inside the delegate are used.

Parse and invoke the specified expression.

Parse and invoke the specified expression.

Parse and invoke the specified expression.

The return type of the expression. Use void or object if you don't know the expected return type.

Gets a list of registeres types. Add types by using the Reference method.

Gets a list of known identifiers. Add identifiers using SetVariable, SetFunction or SetExpression methods.

Gets the available assignment operators.

An expression parameter. This class is thread safe.
