Member Function Documentation

aggregate_size()

virtual size_t PHV::ClusterStats::aggregate_size ( ) const

pure virtual

Returns

the sum of the widths of slices in this cluster.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

contains() [1/2]

virtual bool PHV::ClusterStats::contains ( const PHV::Field * f ) const

pure virtual

Returns

true if this cluster contains f.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

contains() [2/2]

virtual bool PHV::ClusterStats::contains ( const PHV::FieldSlice & slice ) const

pure virtual

Returns

true if this cluster contains slice.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

deparsed()

virtual bool PHV::ClusterStats::deparsed ( ) const

pure virtual

Returns

true if any slice in the cluster is deparsed (either to the wire or the TM).

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

exact_containers()

virtual int PHV::ClusterStats::exact_containers ( ) const

pure virtual

Returns

the number of slices in this container with the exact_containers constraint.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

gress()

virtual gress_t PHV::ClusterStats::gress ( ) const

pure virtual

Returns

the gress requiremnt of this cluster.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

max_width()

virtual int PHV::ClusterStats::max_width ( ) const

pure virtual

Returns

the width of the widest slice in this cluster.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

num_constraints()

virtual int PHV::ClusterStats::num_constraints ( ) const

pure virtual

Returns

the total number of constraints summed over all slices in this cluster.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.

okIn()

virtual bool PHV::ClusterStats::okIn ( PHV::Kind kind ) const

pure virtual

Returns

true if this cluster can be assigned to containers of kind kind.

Implemented in PHV::AlignedCluster, PHV::RotationalCluster, and PHV::SuperCluster.
