walk

public void walk(Consumer<Expression> r)

Description copied from interface: Expression

Traverse this expression.

If this expression is a composite then all its sub-expressions will be traversed.

Specified by:

walk in interface Expression

Parameters:

r - will be called for each Expression contained within this Expression.

replace

public Multiply replace(Function<LeafExpression,LeafExpression> r)

Description copied from interface: Expression

Returns a Expression with LeafExpressions in this Expression replaced with values returned from the given function.

Specified by:

replace in interface Expression

Parameters:

r - returns the LeafExpression to use as a replacement for the LeafExpression it is called with, or null if the original LeafExpression should continue to be used.

Returns:

a new Expression with LeafExpressions in this Expression replaced with versions returned from function.

toString

public String toString()

Overrides:

toString in class Object
