The ruleset rules
read / write, inherited
runtimeType Type
A representation of the runtime type of the object.

selectors List<Selector>
The ruleset selectors
read / write, inherited
treeField Map<String, dynamic>
Fields to show with genTree
read-only, override
type String
Node generic name == class name
unit Unit
read / write
value double
the node value
covariant, read / write, override
visibilityBlocks int
Node visibility control
read / write, inherited


accept(covariant VisitorBase visitor) → void
addVisibilityBlock() → void
blocksVisibility() bool
Returns true if this node represents root of was imported by reference
compare(Node otherNode) int
Returns -1, 0 or +1
convertTo(dynamic conversions) Dimension
Converts a number from one unit into another conversions == 'px', 's' , ... or { length: 'px', duration: 's', angle: 'rad' } String | Map<String, String>
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) Dimension
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. [...]
genCleanCSS(Contexts context, Output output) → void
clean-css output
genCSS(Contexts context, Output output) → void
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
isUnit(String unitString) bool
True if unit is unitString
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. [...]
operate(Contexts context, String op, Dimension other) Dimension
In an operation between two Dimensions, we default to the first Dimension's unit, so 1px + 2 will yield 3px.
removeVisibilityBlock() → void
setParent(dynamic nodes, Node parent) → void
Update parent property in nodes. [...]
throwAwayComments() → void
toColor() Color
toCSS(Contexts context) String
Returns node transformed to css code
toString() String
A string representation of this object. [...]
toTree(LessOptions options) StringBuffer
debug print the node tree
unify() Dimension
Normalize the units to px, s, or rad
visibilityInfo() VisibilityInfo


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