Class | Sass::Tree::Node |
In: |
lib/sass/tree/node.rb
|
Parent: | Object |
The abstract superclass of all parse-tree nodes.
children | [RW] |
The child nodes of this node.
@return [Array<Tree::Node>] |
filename | [W] |
The name of the document on which this node appeared.
@return [String] |
has_children | [RW] |
Whether or not this node has child nodes. This may be true even when
\{children} is empty, in which case this node has an empty block (e.g.
`{}`).
@return [Boolean] |
line | [RW] |
The line of the document on which this node appeared.
@return [Fixnum] |
options | [R] |
The options hash for the node. See {file:SASS_REFERENCE.md#sass_options the
Sass options documentation}.
@return [{Symbol => Object}] |
Appends a child to the node.
@param child [Tree::Node, Array<Tree::Node>] The child node or nodes @raise [Sass::SyntaxError] if `child` is invalid
Compares this node and another object (only other {Tree::Node}s will be equal). This does a structural comparison; if the contents of the nodes and all the child nodes are equivalent, then the nodes are as well.
Only static nodes need to override this.
@param other [Object] The object to compare with @return [Boolean] Whether or not this node and the other object
are the same
@see Sass::Tree
Return a deep clone of this node. The child nodes are cloned, but options are not.
@return [Node]
Converts a static CSS tree (e.g. the output of \{Tree::Visitors::Cssize}) into another static CSS tree, with the given extensions applied to all relevant {RuleNode}s.
@todo Link this to the reference documentation on `@extend`
when such a thing exists.
@param extends [Sass::Util::SubsetMap{Selector::Simple => Selector::Sequence}]
The extensions to perform on this tree
@return [Tree::Node] The resulting tree of static CSS nodes. @raise [Sass::SyntaxError] Only if there‘s a programmer error
and this is not a static CSS tree
True if \{to_s} will return `nil`; that is, if the node shouldn‘t be rendered. Should only be called in a static tree.
@return [Boolean]
Sets the options hash for the node and all its children.
@param options [{Symbol => Object}] The options @see options
Computes the CSS corresponding to this static CSS tree.
@return [String, nil] The resulting CSS @see Sass::Tree
