Class AFlatLinguist.GrammarState

java.lang.Object

edu.cmu.sphinx.linguist.aflat.AFlatLinguist.GrammarState

All Implemented Interfaces:

SearchState, SearchStateArc

Enclosing class:

AFlatLinguist

public class AFlatLinguist.GrammarState
extends java.lang.Object

Represents a grammar node in the search graph. A grammar state needs to keep track of the associated grammar node as well as the left context and next base unit.

Method Detail

getLanguageProbability

public float getLanguageProbability()

Gets the language probability of entering this state

Specified by:

getLanguageProbability in interface SearchStateArc

Returns:

the log probability

hashCode

public int hashCode()

Generate a hashcode for an object. Equality for a grammar state includes the grammar node, the lc and the next base ID

Overrides:

hashCode in class java.lang.Object

Returns:

the hashcode

equals

public boolean equals(java.lang.Object o)

Determines if the given object is equal to this object

Overrides:

equals in class java.lang.Object

Parameters:

o - the object to test

Returns:

true if the object is equal to this

isFinal

public boolean isFinal()

Determines if this is a final state in the search graph

Specified by:

isFinal in interface SearchState

Returns:

true if this is a final state in the search graph

getSuccessors

public SearchStateArc[] getSuccessors()

Gets the set of successors for this state

Specified by:

getSuccessors in interface SearchState

Returns:

the set of successors

getSignature

public java.lang.String getSignature()

Returns a unique string representation of the state. This string is suitable (and typically used) for a label for a GDL node

Specified by:

getSignature in interface SearchState

Returns:

the signature

getOrder

public int getOrder()

Returns the order of this state type among all of the search states

Specified by:

getOrder in interface SearchState

Returns:

the order

toString

public java.lang.String toString()

Returns a string representation of this object

Returns:

a string representation

isEmitting

public boolean isEmitting()

Determines if this state is an emitting state

Specified by:

isEmitting in interface SearchState

Returns:

true if this is an emitting state

getLexState

public java.lang.Object getLexState()

Returns a lex state associated with the searc state (not applicable to this linguist)

Specified by:

getLexState in interface SearchState

toPrettyString

public java.lang.String toPrettyString()

Returns a well formatted string representation of this state

Specified by:

toPrettyString in interface SearchState

Returns:

the formatted string

getWordHistory

public WordSequence getWordHistory()

Returns the word history for this state (not applicable to this linguist)

Specified by:

getWordHistory in interface SearchState

Returns:

the word history (null for this linguist)

getState

public SearchState getState()

Gets a successor to this search state

Specified by:

getState in interface SearchStateArc

Returns:

the successor state

getProbability

public float getProbability()

Gets the composite probability of entering this state

Specified by:

getProbability in interface SearchStateArc

Returns:

the log probability

getInsertionProbability

public float getInsertionProbability()

Gets the insertion probability of entering this state

Specified by:

getInsertionProbability in interface SearchStateArc

Returns:

the log probability
