Types

class ExpressionException(message: String) : RuntimeException

expect class TypedExpressionListener(functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY, constants: (String) -> Any? = { null }) : TypedExpressionListenerBase

actual class TypedExpressionListener(functions: TypedFunctionExtensions, constants: (String) -> Any?) : TypedExpressionListenerBase

TypedExpressionListenerBase

abstract class TypedExpressionListenerBase(val functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY, val constants: (String) -> Any? = { null }) : KeyLangParserBaseListener

A base class for handling typed expressions in a custom language parser. This class provides an extensive set of overrides for various parser rules to allow custom implementation when these rules are triggered during parsing.

TypedFunction0

typealias TypedFunction0 = () -> Any

TypedFunction1

typealias TypedFunction1 = (Any) -> Any

TypedFunction2

typealias TypedFunction2 = (Any, Any) -> Any

TypedFunction3

typealias TypedFunction3 = (Any, Any, Any) -> Any

TypedFunction4

typealias TypedFunction4 = (Any, Any, Any, Any) -> Any

TypedFunction5

typealias TypedFunction5 = (Any, Any, Any, Any, Any) -> Any

TypedFunctionExtensions

class TypedFunctionExtensions(val functions0: Map<String, TypedFunction0> = emptyMap(), val functions1: Map<String, TypedFunction1> = emptyMap(), val functions2: Map<String, TypedFunction2> = emptyMap(), val functions3: Map<String, TypedFunction3> = emptyMap(), val functions4: Map<String, TypedFunction4> = emptyMap(), val functions5: Map<String, TypedFunction5> = emptyMap())

Functions

abs

fun abs(x: Any): Any

compileFunction1

fun <T0, R> compileFunction1(expression: String, parameter0: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY): (T0) -> R

Compiles a string expression into a single-parameter function capable of evaluating the expression.

compileFunction1OrNull

fun <T0, R> compileFunction1OrNull(expression: String, parameter0: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY, onError: (Throwable) -> Unit = { }): (T0) -> R?

Tries to compile a given string expression into a single-parameter function. Returns the compiled function if successful, or null if an error occurs during compilation. Errors are handled using the provided onError callback.

compileFunction2

fun <T0, T1, R> compileFunction2(expression: String, parameter0: String, parameter1: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY): (T0, T1) -> R

Compiles a string expression into a lambda function with two parameters.

compileFunction2OrNull

fun <T0, T1, R> compileFunction2OrNull(expression: String, parameter0: String, parameter1: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY, onError: (Throwable) -> Unit = { }): (T0, T1) -> R?

Attempts to compile a string expression into a lambda function with two parameters, returning null if an error occurs during compilation.

compileFunction3

fun <T0, T1, T2, R> compileFunction3(expression: String, parameter0: String, parameter1: String, parameter2: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY): (T0, T1, T2) -> R

Compiles a 3-parameter function from a given string expression, allowing dynamic evaluation with specified parameters, constants, and external function extensions.

compileFunction3OrNull

fun <T0, T1, T2, R> compileFunction3OrNull(expression: String, parameter0: String, parameter1: String, parameter2: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY, onError: (Throwable) -> Unit = { }): (T0, T1, T2) -> R?

Compiles a 3-parameter function from a given string expression, returning null if an error occurs during compilation.

compileTypedExpression

fun compileTypedExpression(expression: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY): () -> Any

Compiles a typed expression and returns a lambda that can execute the compiled expression.

evaluateTypedExpression

fun evaluateTypedExpression(expression: String, constants: (String) -> Any? = { null }, functions: TypedFunctionExtensions = TypedFunctionExtensions.EMPTY): Any?

Evaluates a typed expression based on the provided string input, constants, and function definitions.
