Constructor Detail

ConsecutiveOperations

public ConsecutiveOperations(java.util.List<VtreeOperation> ops)

Creates the operation defined as the application of the specified list of vtree operations.

Parameters:

ops - the list of operations to apply.

Method Detail

isApplicable

public boolean isApplicable(Vtree tree)

Description copied from interface: VtreeOperation

Indicates whether this operation is applicable for the specified vtree.

Specified by:

isApplicable in interface VtreeOperation

Parameters:

tree - the vtree on which we want to perform this operation.

Returns:

true if this operation can be applied on tree.

apply

public Vtree apply(Vtree tree)

Description copied from interface: VtreeOperation

Computes the new vtree after application of this operation on the specified vtree.

Specified by:

apply in interface VtreeOperation

Parameters:

tree - the vtree on which the operation is applied.

Returns:

the vtree obtained by applying this operation on tree.

applyToSDD

public SDDTree applyToSDD(SDDTree sdd,
                 SDDMemory mem)

Description copied from interface: VtreeOperation

Computes the SDD tree (associated with the vtree on which this operation is applied) that are equivalent to the specified SDD tree defined for the specified vtree.

Specified by:

applyToSDD in interface VtreeOperation

Parameters:

sdd - the SDD tree that is reformulated.

mem - the memory used to store known results.

Returns:

an SDD tree equivalent to sdd but over apply(tree).
