Constructor Detail

DefaultProgramState

public DefaultProgramState(HeapConfiguration heap)

Initializes a program state.

Parameters:

heap - The underlying heap configuration.

DefaultProgramState

protected DefaultProgramState(DefaultProgramState state)

Creates a copy of the state.

Parameters:

state - The state to be copied.

Method Detail

shallowCopy

public ProgramState shallowCopy()

Description copied from interface: ProgramState

Creates a shallow copy of this program state in which the underlying heap configuration is the same as in the copied object.

Returns:

A shallow copy of this program state.

shallowCopyUpdatePC

public ProgramState shallowCopyUpdatePC(int newPC)

Description copied from interface: ProgramState

Creates a shallow copy of this program state in which the underlying heap configuration is the same as in the copied object. The program counter of the copy is set to the provided new program counter value.

Parameters:

newPC - The value of the program counter of the copy.

Returns:

A shallow copy of this program state with the given program counter.

                                  SelectorLabel selectorLabel)

Specified by:

getSelectorTargetOf in class GeneralProgramState

removeSelector

protected void removeSelector(int sourceNode,
                              SelectorLabel selectorLabel)

Specified by:

Specified by:

clone in interface ProgramState

Specified by:

clone in class GeneralProgramState

Returns:

A deep copy of this program state.

equals

public boolean equals(Object other)

Overrides:

equals in class Object
