Method Detail

applyTo

public void applyTo(Cube cube,
                    boolean inverse)

Applies the symbol represented by this node to the cube.

Overrides:

applyTo in class Node

Parameters:

cube - A cube to be transformed by this symbol.

inverse - If true, the transform will be done in inverse order.

resolvedEnumeration

public java.util.Enumeration resolvedEnumeration(boolean inverse)

Enumerate this symbol and all of its children. Special operators (i. e. repeat and inverse) are resolved before the children are returned.

Overrides:

resolvedEnumeration in class Node

Parameters:

inverse - Set to true if you wish to get an inverted enumeration.

writeTokens

public void writeTokens(java.io.PrintWriter w,
                        Notation p,
                        java.util.Map<java.lang.String,MacroNode> macroMap)
                 throws java.io.IOException

Description copied from class: Node

Writes the token(s) represented by the subtree starting at this node. The syntax and the string representations of the tokens are provided by the parser.

Overrides:

writeTokens in class Node

Parameters:

w - This is where the tokens are written to.

p - The notation which provides the tokens.

macroMap - Local macros which are preserved by the translation.

Throws:

java.io.IOException

toResolvedList

public java.util.List toResolvedList()

Overrides:

toResolvedList in class Node
