Modifier and Type	Method	Description
boolean	add(IndexArg indexArg, State state)
int	argSize(IndexArg indexArg)
protected IndexArgs	checkIfList(IndexArg indexArg, State state)
int	count()	Only works if there are no wildcards! This counts the number of indices that will be computed.
ArrayList<IndexList>	createSourceIndices()	indexArgs are [a1,a2,a3,a4,a5,...,ak] with sizes [n1,n2,n3,n4,n5,...,nk] nu = n1*n2*...*nk Each iteration has nu passes.
ArrayList<IndexList>	createTargetIndices()	These are the indices for the result.
boolean	hasWildcard()	Does one of the index args have a wildcard?
boolean	isAllWildcards()	If one (except the zero-th element, which is the actual stem) is all wildcards.

IndexArgs

public IndexArgs()

Method Detail

hasWildcard

public boolean hasWildcard()

Does one of the index args have a wildcard?

Returns:

isAllWildcards

public boolean isAllWildcards()

If one (except the zero-th element, which is the actual stem) is all wildcards.

Returns:

count

public int count()

Only works if there are no wildcards! This counts the number of indices that will be computed.

Returns:

argSize

public int argSize(IndexArg indexArg)

createSourceIndices

public ArrayList<IndexList> createSourceIndices()

 indexArgs are [a1,a2,a3,a4,a5,...,ak] with sizes [n1,n2,n3,n4,n5,...,nk]
 nu = n1*n2*...*nk
 Each iteration has nu passes.
 each period is nu1= nu/n1, nu2 = nu/(nu1*n2), nu3 = nu/(nu2*n3),...
 

Returns:

createTargetIndices

public ArrayList<IndexList> createTargetIndices()

These are the indices for the result.

Returns:

add

public boolean add(IndexArg indexArg,
                   State state)

checkIfList

protected IndexArgs checkIfList(IndexArg indexArg,
                                State state)
