Parameters:

token - The token

Returns:

The frequency or null

hasTokenFrequencyInfo

public boolean hasTokenFrequencyInfo()

getSuggestions

public Map<Token,LinkedHashMap<String,Integer>> getSuggestions()

All the suggestions. The ordering of the inner LinkedHashMap is by best suggestion first.

Returns:

The Map of suggestions for each Token. Key is the token, value is a LinkedHashMap whose key is the Suggestion and the value is the frequency or NO_FREQUENCY_INFO if frequency info is not available.

getTokenFrequency

public Map<Token,Integer> getTokenFrequency()

getTokens

public Collection<Token> getTokens()

Returns:

The original tokens

setTokens

public void setTokens(Collection<Token> tokens)
