Constructor Detail

NestedModel

public NestedModel(int labelNum,
                   String specs)
            throws Exception

Throws:

Exception

Method Detail

main

public static void main(String[] args)

getEdgeIterator

public EdgeIterator getEdgeIterator()

Returns:

the iterator for edges

innerEdgeIterator

public EdgeIterator innerEdgeIterator()

getStateNum

public int getStateNum()

Description copied from interface: ModelGraph

Gets the number of states. It is always equal to the number of labels except for the nested model.

Specified by:

getStateNum in interface ModelGraph

Overrides:

getStateNum in class AbstractModel

Returns:

the number of states

getEdgeNum

public int getEdgeNum()

Returns:

the number of edges

getLabel

public int getLabel(int stateNum)

Description copied from interface: ModelGraph

Gets the label of the state. The label and the state should be the same except for nested models.

Parameters:

stateNum - the index of the state

Returns:

the label of the state

getStartStateNum

public int getStartStateNum()

Returns:

the number of states which can serve as starting states

getEndStateNum

public int getEndStateNum()

Returns:

the number of states which can serve as ending states

getStartState

public int getStartState(int i)

Description copied from interface: ModelGraph

Gets the index-th starting state. The index is between zero and the number of starting states minor one

Parameters:

i - the index-th starting state

Returns:

the index-th starting state.

getEndState

public int getEndState(int i)

Description copied from interface: ModelGraph

Gets the index-th ending state. The index is between zero and the number of ending states minor one

Parameters:

i - the index-th ending state

Returns:

the index-th ending state.

isEndState

public boolean isEndState(int i)

Description copied from interface: ModelGraph

Tests if the i-th state is an ending state

Parameters:

i - the i-th state

Returns:

true if the i-th state is an ending state

isStartState

public boolean isStartState(int i)

Description copied from interface: ModelGraph

Tests if the i-th state is a starting state

Parameters:

i - the i-th state

Returns:

true if the i-th state is a starting state

mapStateToLabel

public boolean mapStateToLabel(DataSequence dataSeq)

Description copied from interface: ModelGraph

Maps states to labels. It does nothing unless nested model

Specified by:

mapStateToLabel in interface ModelGraph

Overrides:

mapStateToLabel in class AbstractModel

Parameters:

dataSeq - the sequence for mapping

Returns:

true if mapping successfully

mapLabelToState

public boolean mapLabelToState(DataSequence data)

Description copied from interface: ModelGraph

Maps labels to states. It does nothing unless nested model.

Specified by:

mapLabelToState in interface ModelGraph

Overrides:

mapLabelToState in class AbstractModel

Parameters:

data - the sequence for mapping

Returns:

true if mapping successfully
