Environment class - parser library

Constructors

Environment.new([Map<String, dynamic> data = const {}, Map<String, dynamic>? register, bool strictMode = false]): Constructs a new Environment instance with the provided initial data.
Environment.withStrictMode([Map<String, dynamic> data = const {}, Map<String, dynamic>? register])

Properties

hashCode → int: The hash code for this object.
no setterinherited
registers → Map<String, dynamic>: no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
strictMode → bool: Gets the current strict mode setting.
no setter

Methods

all() → Map<String, dynamic>: Returns a map containing all variables in the current context.
call(String key) → dynamic
clear() → void: Clears the variable stack and adds a new global scope.
clone() → Environment: Creates a new Environment instance that is a deep copy of the current instance.
getAvailableFilters() → List<String>: Returns a list of all available filter names (local + global unless in strict mode).
getAvailableTags() → List<String>: Returns a list of all available tag names (local + global unless in strict mode).
getFilter(String name) → FilterFunction?: Gets the filter function registered with the given name.
getRegister(String key) → dynamic
getRoot() → Root?
getTag(String name) → TagCreator?: Gets a tag creator function, checking local registrations first, then global.
getVariable(String name) → dynamic: Retrieves the value of a variable from the current scope or any parent scopes.
merge(Map<String, dynamic> newData) → void: Merges new data into the current scope.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
popScope() → void: Removes the most recently added scope from the variable stack.
pushScope() → void: Pushes a new scope onto the variable stack.
registerFilter(String name, FilterFunction function) → void: Registers a new filter function with the given name.
registerLocalFilter(String name, FilterFunction function) → void: Registers a local filter function that is only available in this environment.
registerLocalTag(String name, TagCreator creator) → void: Registers a local tag creator function that is only available in this environment.
removeRegister(String s) → void
setRegister(String key, dynamic value) → void
setRoot(Root? root) → void
setStrictMode(bool strict) → void: Sets strict mode for the environment. When strict mode is enabled, only locally registered filters and tags are accessible. Global registries are ignored in strict mode.
setVariable(String name, dynamic value) → void: Sets a variable in the current scope.
toString() → String: A string representation of this object.

Operators

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