Method Detail

replaceNodeAt

public void replaceNodeAt(int index,
                          Node newChild)

Replace the child at the given position with another node.

Parameters:

index - the position of the old node that is to be replaced

newChild - replacing node

replaceNode

public void replaceNode(Node oldChild,
                        Collection<? extends Node> newNodes)

Replace the child oldChild with a collection of nodes.

Parameters:

oldChild - child to replace

newNodes - replacing nodes, can be an empty collection

appendChild

public void appendChild(Node node)

Append a new child node to the end of the child list. This method should only be used when constructing the Node tree, not when modifying it.

Parameters:

node - new child to append

getChildren

public List<Node> getChildren()

setChildren

@Deprecated
protected void setChildren(Collection<Node> newChildren)

Deprecated.

traverse

public abstract Collection<Node> traverse(ScssContext context)

Method for manipulating the data contained within the Node. Traversing a node is allowed to modify the node, replace it with one or more nodes at the same or later position in its parent and modify the children of the node, but not modify or remove preceding nodes in its parent. Traversing a node is also allowed to modify the definitions currently in scope as its side-effect.

Parameters:

context - current compilation context

Returns:

nodes replacing the current node

printState

public String printState()

Prints out the current state of the node tree. Will return SCSS before compile and CSS after. Result value could be null.

Returns:

State as a string

getParentNode

public Node getParentNode()

getNormalParentNode

public Node getNormalParentNode()

copy

public abstract Node copy()

Copy a node (deep copy including children). The copy is detached from the original tree, with null as parent, and data that is not relevant to handling of function or mixin expansion is not copied.

Returns:

copy of the node

copyChildren

protected Collection<Node> copyChildren()

traverseChildren

public Collection<Node> traverseChildren(ScssContext context)

traverseChildren

protected Collection<Node> traverseChildren(ScssContext context,
                                            boolean newScope)
