Method Detail

setIDPrefix

public void setIDPrefix(String identifierPrefix)

set the prefix of identifier keys

Parameters:

identifierPrefix - the prefix that is used to create key values

excludeKey

public void excludeKey(String keyToExclude)

Description copied from interface: IDGeneratorService

excludes a key as a possible value to generate. This is used when Project35 reads a file that contains identifiers. This method ensures that the service won't return a value that already appears somewhere in the data set.

Specified by:

excludeKey in interface IDGeneratorService

Parameters:

keyToExclude - an identifier value that can't be generated by the ID Generator service

getParameters

public Parameter[] getParameters()

generateKey

public String generateKey(Project35FormContext project35FormContext)

Description copied from interface: IDGeneratorService

generates an identifier value that Project35 can insert into a field that takes ID values

Specified by:

generateKey in interface IDGeneratorService

Parameters:

project35FormContext - collection of environment variables that can be used to access different parts of the Project35 application. Information in these variables may help determine the best identifier to return.
