The context model keeps track of all known variables and functions.
It is structured hierarchically to offer nested scopes.
Constructors
- ContextModel()
-
Creates a new, empty root context model.
Properties
- functions → Set<MathFunction>
-
Function set of this scope.
read / write - hashCode → int
-
Get a hash code for this object.…
read-only, inherited - parentScope → ContextModel
-
The parent scope.
read / write - runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited - variables → Map<String, Expression>
-
Variable map of this scope (name -> expression).
read / write
Operators
-
operator ==(
other) → bool -
The equality operator.…

Methods
-
bindFunction(
MathFunction f) → void -
Binds a function to this context.
-
bindVariable(
Variable v, Expression e) → void -
Binds a variable to an expression in this context.
-
bindVariableName(
String vName, Expression e) → void -
Binds a variable name to an expression in this context.
-
createChildScope(
) → ContextModel -
Returns a new child scope of this scope.
-
getExpression(
String varName) → Expression -
Returns the bound expression for the given variable. Performs recursive lookup through
parentScope
.… -
getFunction(
String name) → MathFunction -
Returns the function for the given function name. Performs recursive lookup through
parentScope
.… -
noSuchMethod(
Invocation invocation) → dynamic -
noSuchMethod
is invoked when users invoke a non-existent method on an object. The name of the method and the arguments of the invocation are passed tonoSuchMethod
in anInvocation
. IfnoSuchMethod
returns a value, that value becomes the result of the original invocation.…inherited -
toString(
) → String -
Returns a string representation of this object.
