read / write
elements ↔ List<Element>: Selector elements
read / write

read-only, inherited
id ↔ int: hashCode own or inherited for object comparation
read / write
index ↔ int: index from this node or their parent, position in the less file
read / write

read / write
name → dynamic: Node name
read-only
nodeVisible ↔ bool: Only output css code for nodeVisible = true
read / write
operands ↔ List<Node>: For operation node
read / write
originalRuleset ↔ Node: for Rulesets and mixins process
read / write
parens ↔ bool: The node has been parsed inside parenthesis ()
read / write
parensInOp ↔ bool: for expression evaluation
read / write
parent ↔ Node: parent Node, used by index and fileInfo.
read / write
parsed ↔ bool: Some anonymous nodes are lazy parsed
read / write
rootNode ↔ bool: read / write
rules ↔ List<Node>: The ruleset rules
read / write
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited
selectors ↔ List<Selector>: The ruleset selectors
read / write
treeField → Map<String, dynamic>: Fields to show with genTree
read-only
type → String: Node generic name == class name
read-only

read / write

Methods

accept(VisitorBase visitor) → void
addVisibilityBlock() → void
blocksVisibility() → bool: Returns true if this node represents root of was imported by reference
copyVisibilityInfo(VisibilityInfo info) → void: This node get the visibility from info
ensureInvisibility() → void: Turns off node visibility - if called node will NOT be shown in output regardless of whether it comes from import by reference or not
ensureVisibility() → void: Turns on node visibility, that is, if called node will be shown in output regardless of whether it comes from import by reference or not
eval(Contexts context) → Node: Default evaluation - returns the node
fileInfo() → FileInfo: returns fileInfo from this node or their parent
fround(Contexts context, num value, [int precision]) → num: Adjust the precision of value according to context.numPrecision. 8 By default. [...]
genCSS(Contexts context, Output output) → void: Writes in output the node transformed to CSS.
genTree(Contexts env, Output output, [String prefix = '']) → void: Writes in output the tree, for debug
genTreeField(Contexts env, Output output, String fieldName, dynamic fieldValue) → void: Build the subtree for a fieldName, fieldValue
genTreeTitle(Contexts env, Output output, String prefix, String type, String value) → void: Build the node tree title
getIndex() → int: returns index from this node or their parent
isCharset() → bool: Directive overrides it
isRulesetLike() → bool
isVisible() → bool: return values: false - the node must not be visible true - the node must be visible null - the node has the same visibility as its parent
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
removeVisibilityBlock() → void
setParent(dynamic nodes, Node parent) → void: Update parent property in nodes. [...]
throwAwayComments() → void
toCSS(Contexts context) → String: Returns node transformed to css code
toString() → String: Returns a string representation of this object.
inherited
toTree(LessOptions options) → StringBuffer: debug print the node tree
visibilityInfo() → VisibilityInfo

Operators

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

Static Methods

compareNodes(Node a, Node b) → int: Compares two nodes a and b [...]
numericCompare(num a, num b) → int: numeric comparision between two number a and b [...]
