ICacheAble

public class SimpleMDAGNode
extends Object
implements ICacheAble

The class capable of representing a MDAG node, its _transition set, and one of its incoming transitions; objects of this class are used to represent a MDAG after its been simplified in order to save space.

构造方法详细信息

SimpleMDAGNode

public SimpleMDAGNode(char letter,
                      boolean isAcceptNode,
                      int transitionSetSize)

Constructs a SimpleMDAGNode.

参数：

letter - a char representing the _transition label leading to this SimpleMDAGNode

isAcceptNode - a boolean representing the accept state status of this SimpleMDAGNode

transitionSetSize - an int denoting the size of this _transition set

SimpleMDAGNode

public SimpleMDAGNode()

方法详细信息

getLetter

public char getLetter()

Retrieves the character representing the _transition laben leading up to this node.

返回：

the char representing the _transition label leading up to this node

isAcceptNode

public boolean isAcceptNode()

Retrieves the accept state status of this node.

返回：

true if this node is an accept state, false otherwise

getTransitionSetBeginIndex

public int getTransitionSetBeginIndex()

Retrieves the index in this node's containing array that its _transition set begins at.

返回：

an int of the index in this node's containing array at which its _transition set begins

getOutgoingTransitionSetSize

public int getOutgoingTransitionSetSize()

Retrieves the size of this node's outgoing _transition set.

返回：

an int denoting the size of this node's outgoing _transition set

setTransitionSetBeginIndex

public void setTransitionSetBeginIndex(int transitionSetBeginIndex)

Records the index in this node's containing array that its _transition set begins at.

参数：

transitionSetBeginIndex - an int denoting the index in this node's containing array that is _transition set beings at

transition

public SimpleMDAGNode transition(SimpleMDAGNode[] mdagDataArray,
                                 char letter)

Follows an outgoing _transition from this node.

参数：

mdagDataArray - the array of SimpleMDAGNodes containing this node

letter - the char representation of the desired _transition's label

返回：

the SimpleMDAGNode that is the target of the _transition labeled with letter, or null if there is no such labeled _transition from this node

transition

public SimpleMDAGNode transition(SimpleMDAGNode[] mdagDataArray,
                                 String str)

Follows a _transition path starting from this node.

参数：

mdagDataArray - the array of SimpleMDAGNodes containing this node

str - a String corresponding a _transition path in the MDAG

返回：

the SimpleMDAGNode at the end of the _transition path corresponding to str, or null if such a _transition path is not present in the MDAG

transition

public SimpleMDAGNode transition(SimpleMDAGNode[] mdagDataArray,
                                 char[] str)

transition

public SimpleMDAGNode transition(SimpleMDAGNode[] mdagDataArray,
                                 char[] str,
                                 int offset)

traverseMDAG

public static SimpleMDAGNode traverseMDAG(SimpleMDAGNode[] mdagDataArray,
                                          SimpleMDAGNode sourceNode,
                                          String str)

Follows a _transition path starting from the source node of a MDAG.

参数：

mdagDataArray - the array containing the data of the MDAG to be traversed

sourceNode - the dummy SimpleMDAGNode which functions as the source of the MDAG data in mdagDataArray

str - a String corresponding to a _transition path in the to-be-traversed MDAG

返回：
