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
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
