Method Summary

List<QueryLiteral>	getValues(com.atlassian.crowd.embedded.api.User searcher, String field, Operand operand)
boolean	isEmptyOperand(com.atlassian.crowd.embedded.api.User searcher, String field, Operand operand) Returns true if the operand represents an EMPTY operand.
boolean	isFunctionOperand(com.atlassian.crowd.embedded.api.User searcher, String field, Operand operand) Returns true if the passed operand is a function call.
boolean	isListOperand(com.atlassian.crowd.embedded.api.User searcher, String field, Operand operand) Returns true if the passed operand returns a list of values.

Method Detail

getValues

List<QueryLiteral> getValues(com.atlassian.crowd.embedded.api.User searcher,
                             String field,
                             Operand operand)

Parameters:

searcher - the User performing the lookup

field - a String representing the field over which you are searching

operand - the Operand containing the values used to search

Returns:

a List of values obtained from the operand

isEmptyOperand

boolean isEmptyOperand(com.atlassian.crowd.embedded.api.User searcher,
                       String field,
                       Operand operand)

Returns true if the operand represents an EMPTY operand.

Parameters:

operand - the operand to check if it is a EMPTY operand

Returns:

true if the operand is an EMPTY operand, false otherwise.

isFunctionOperand

boolean isFunctionOperand(com.atlassian.crowd.embedded.api.User searcher,
                          String field,
                          Operand operand)

Returns true if the passed operand is a function call.

Parameters:

operand - the operand to check. Cannot be null.

Returns:

true of the passed operand is a function operand, false otherwise.

isListOperand

boolean isListOperand(com.atlassian.crowd.embedded.api.User searcher,
                      String field,
                      Operand operand)

Returns true if the passed operand returns a list of values.

Parameters:

operand - the operand to check. Cannot be null.

Returns:

true if the passed operand returns a list of values or false otherwise.
