Constructor Detail

VariableNode

public VariableNode(String name,
                    SassListItem expr,
                    boolean guarded)

Method Detail

getExpr

public SassListItem getExpr()

setExpr

public void setExpr(SassListItem expr)

getName

public String getName()

Specified by:

getName in interface Definition

isGuarded

public boolean isGuarded()

getVariable

public Variable getVariable()

printState

public String printState()

Description copied from class: Node

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

Overrides:

printState in class Node

Returns:

State as a string

toString

public String toString()

Overrides:

toString in class Object

replaceVariables

public void replaceVariables(ScssContext context)

Specified by:

replaceVariables in interface IVariableNode

traverse

public Collection<Node> traverse(ScssContext context)

Description copied from class: Node

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.

Specified by:

traverse in class Node

Parameters:

context - current compilation context

Returns:

nodes replacing the current node

copy

public VariableNode copy()

Description copied from class: Node

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.

Specified by:

copy in class Node

Returns:

copy of the node

updateUrl

public VariableNode updateUrl(String prefix)

Description copied from interface: NodeWithUrlContent

Returns a new Node that is otherwise identical to this but has all urls updated by adding the specified prefix and cleaning the resulting path to, e.g., eliminate redundant parent folder references. Does not modify this node.

Specified by:

updateUrl in interface NodeWithUrlContent

Parameters:

prefix - the prefix to be added to all urls contained in this Node.
