A concrete implementation of DartBlockArbiter.

This class keeps track of the console output of the executed DartBlockProgram, as well as the actual execution behavior.

Methods

assignValueToVariable(String name, DartBlockValue? value) → void
Used by VariableAssignmentStatement to update an existing (declared) variable's value.
inherited
beginScope(int key, {dynamic isIsolated = false}) → void
Begin a new scope for variables, represented by a DartBlockEnvironment object.
inherited
copyFrom(DartBlockExecutor executor) → void
Copy the state of another DartBlockExecutor into this one.
declareVariable(DartBlockDataType dataType, String name, DartBlockValue? value) → void
Used by VariableDeclarationStatement to declare a new variable with an optional initial value, i.e., its initial value can be null.
inherited
endScope(int key) → void
End the current scope (DartBlockEnvironment) and return to the previous ('higher-up' or parent) scope. This is done by retrieving and removing the last element in the _blockHistory list.
inherited
execute({Duration duration = const Duration(seconds: 5)}) → Future<void>
Execute the DartBlockProgram.
getVariableValue(String name) → DartBlockValue?
Retrieve the value assigned to the given variable in the current scope (DartBlockEnvironment), based on its unique name.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
printToConsole(String message) → void
Print a message to the console.
override
retrieveCustomFunction(String name) → DartBlockFunction?
Retrieve a DartBlockFunction based on its unique name.
inherited
toString() → String
A string representation of this object.
inherited
verifyDataTypeOfConcreteValue(DartBlockDataType expectedType, dynamic value) → (bool, Type?)
Whether a given value's type matches expectedType.
inherited
verifyDataTypeOfNeoValue(DartBlockDataType expectedType, DartBlockValue value) → (bool, Type?)
Whether a given value's type matches expectedType.

Operators

operator ==(Object other) → bool
The equality operator.
