walk

public void walk(Consumer<Expression> r)

Description copied from interface: Constraint

Traverse this constraint.

Specified by:

walk in interface Constraint

Specified by:

walk in interface Expression

Parameters:

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

replace

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

Description copied from interface: Constraint

Returns new Constraint with LeafExpressions in this Constraint replaced with values returned from the given function.

Specified by:

replace in interface Constraint

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 Constraint with LeafExpressions in this Constraint replaced with versions returned from function.
