public abstract class AbstractUserBasedFunction
extends AbstractJqlFunction

This is an abstract parent to user based functions that rely on returning a list of a list of QueryLiteral based on either the current user or a user passed as a parameter.

This function expects zero or one argument. If zero arguments are supplied the current logged in user will be used.

Since:

v4.2

Method Summary

protected abstract List<QueryLiteral>	getFunctionValuesList(QueryCreationContext queryCreationContext, FunctionOperand operand, com.atlassian.crowd.embedded.api.User user) Get the function return values based on the actual user.
int	getMinimumNumberOfExpectedArguments() This method must return the number of arguments that the function expects to perform its operation correctly.
protected abstract String	getUserNotFoundMessageKey() Get the I18n message key for the error when the passed in user does not exist.
List<QueryLiteral>	getValues(QueryCreationContext queryCreationContext, FunctionOperand functionOperand, TerminalClause terminalClause) Gets the unexpanded values provided by the user on input.
MessageSet	validate(com.atlassian.crowd.embedded.api.User searcher, FunctionOperand functionOperand, TerminalClause terminalClause) Will validate the function operand's arguments and report back any errors.

Method Detail

validate

public MessageSet validate(com.atlassian.crowd.embedded.api.User searcher,
                           FunctionOperand functionOperand,
                           TerminalClause terminalClause)

Description copied from interface: JqlFunction

Will validate the function operand's arguments and report back any errors.

Parameters:

searcher - the user performing the search

functionOperand - the operand to validate

terminalClause - the terminal clause that contains the operand

Returns:

a MessageSet which will contain any validation errors or warnings or will be empty if there is nothing to report; never null.

getMinimumNumberOfExpectedArguments

public int getMinimumNumberOfExpectedArguments()

Description copied from interface: JqlFunction

This method must return the number of arguments that the function expects to perform its operation correctly. If the function can accept a variable number of arguments this value should be the lower limit. It is perfectly legal for a function to take no arguments and return 0 for this method.

Returns:

the number of arguments that the function expects to perform its operation correctly. Must be >=0.

getValues

public List<QueryLiteral> getValues(QueryCreationContext queryCreationContext,
                                    FunctionOperand functionOperand,
                                    TerminalClause terminalClause)

Description copied from interface: JqlFunction

Gets the unexpanded values provided by the user on input. This is the output values that will later be transformed into index values.

For example, a function who returns all the released versions of a specified project should return QueryLiterals representing the ids of those versions. For correctness, always opt to return the most specific identifier for the object; if you can return either the id (which is stored in the index) or a string name (that would require resolving to get the index value), choose the id.

Parameters:

queryCreationContext - the context of query creation

functionOperand - the operand to get values from

terminalClause - the terminal clause that contains the operand

Returns:

a List of objects that represent this Operands raw values. Cannot be null.

getFunctionValuesList

protected abstract List<QueryLiteral> getFunctionValuesList(QueryCreationContext queryCreationContext,
                                                            FunctionOperand operand,
                                                            com.atlassian.crowd.embedded.api.User user)

Get the function return values based on the actual user. transformed into index values.

Parameters:

queryCreationContext - the context of query creation

operand - the operand to get values from

user - the user

Returns:

a List of objects that represent this Operands raw values. Cannot be null.

getUserNotFoundMessageKey

protected abstract String getUserNotFoundMessageKey()

Get the I18n message key for the error when the passed in user does not exist.

Returns:

message key.
