Constructor Detail

SignedRedirectedStringMap

public SignedRedirectedStringMap(long numberOfDocuments,
                                 Object2LongFunction<CharSequence> signedFunction,
                                 long[] target)

Creates a new signed redirected map.

Parameters:

numberOfDocuments - the threshold after which the target array will be used to compute the output.

signedFunction - the base signed function.

target - an array providing the output for items beyond numberOfDocuments; it must be long as the size of signedFunction minus numberOfDocuments.
