Method Detail

add

public void add(Op op)

Accumulate an op in the OpN. This exists to help building OpN in the first place. Once built, an OpN, like any Op should be treated as immutable with no calls change the sub ops contents. No calls to .add.

get

public Op get(int idx)

apply

public abstract Op apply(Transform transform,
                         java.util.List<Op> elts)

copy

public abstract OpN copy(java.util.List<Op> elts)

size

public int size()

hashCode

public int hashCode()

Specified by:

hashCode in class OpBase

getElements

public java.util.List<Op> getElements()

iterator

public java.util.Iterator<Op> iterator()
