Constructor Detail

NestedDoStatement

public NestedDoStatement(Xnode outerDoStatement)

Constructs a group of nested do statements from the outer statement.

Parameters:

outerDoStatement - Do statement on the outer level.

NestedDoStatement

public NestedDoStatement(Xnode outerDoStatement,
                         int nb)

Constructs a group of nested do statements from the outer statement with maximum Nb do statements.

Parameters:

outerDoStatement - Do statement node to start the nested group.

nb - Number of do statements. If nb ≤ 0 match all possible nested do statement.

NestedDoStatement

public NestedDoStatement(java.util.List<DimensionDefinition> dimensions,
                         XcodeProgram xcodeml)

Constructs a group of nested do statements from a list of dimension objects. The outer statement represents the first element of the list and the inner statement represents the last element of the list.

Parameters:

dimensions - A list of dimension objects.

xcodeml - The current XcodeML program unit in which the elements will be created.

Method Detail

getOuterStatement

public Xnode getOuterStatement()

Get the outer do statements. First do statement in the nested group.

Returns:

XdoStatement holding information about the outer do statement.

get

public Xnode get(int i)

Get statement at level i

Parameters:

i - Level index starts at 0 for outer do statement.

Returns:

The do statement at level i.

getInductionVariables

public java.util.List<java.lang.String> getInductionVariables()

Get all the induction variable in the nested do statement group.

Returns:

List of induction variable as string.

computeSwappingIndices

public int computeSwappingIndices(java.util.List<java.lang.String> newInductionVarOrder)

Compute the swapping indices for the new ordering. Gives new position position of the xth index from right to left. E.g. current to new position: i,j,k → k,i,j = 120 i goes to pos 1, j goes to pos 2 and k goes to pos 0.

Parameters:

newInductionVarOrder - List of induction variable in their new order.

Returns:

Computed new position indices.

getInnerStatement

public Xnode getInnerStatement()

Get the inner do statements. Last do statement in the nested group.

Returns:

XdoStatement holding information about the inner do statement.

size

public int size()

Get the size of the group of nested do statements.

Returns:

Size of the group.

cloneNestedGroup

public NestedDoStatement cloneNestedGroup()

Clone current nested group with all its elements.

Returns:

Newly created nested do statements group.
