Method Detail

getParamFromQueryParams

public static String getParamFromQueryParams(org.apache.sling.api.SlingHttpServletRequest request,
                                             String parameterName)

Parameters:

request - the request object.

parameterName - The request query parameter name.

Returns:

a String representation of the query parameter parameterName. If no request parameter can be found with that name, the empty string is returned.

isOptionInInitialValues

public static boolean isOptionInInitialValues(com.adobe.cq.wcm.core.components.models.form.OptionItem optionItem,
                                              org.apache.sling.api.resource.ValueMap initialValues)

Determines if the optionItem's value exists as a value in the initialValues map.

Parameters:

optionItem - the option item.

initialValues - the initial values.

Returns:

true if optionItem's value is in initialValues.

isOptionInInitialValues

public static boolean isOptionInInitialValues(String value,
                                              org.apache.sling.api.resource.ValueMap initialValues)

Determines if the value exists as a value in the initialValues map. Only String and String[] intialValues values are supported.

Parameters:

value - the value to check.

initialValues - the initial values.

Returns:

true if value is in initialValues.

getInitialValue

public static String getInitialValue(org.apache.sling.api.SlingHttpServletRequest request,
                                     Predicate predicate,
                                     String predicateValueName)

Finds initial predicate value from the request.

Parameters:

request - the request.

predicate - the predicate.

predicateValueName - the predicate value name.

Returns:

a map of the initial values.

getInitialValues

public static org.apache.sling.api.resource.ValueMap getInitialValues(org.apache.sling.api.SlingHttpServletRequest request,
                                                                      Predicate predicate,
                                                                      String predicateValueName)

Finds initial predicate values from the request.

Parameters:

request - the request.

predicate - the predicate.

predicateValueName - the predicate value name.

Returns:

a map of the initial values.

findPredicate

public static org.apache.sling.api.resource.ValueMap findPredicate(Map<String,String> queryBuilderParams,
                                                                   String predicateName,
                                                                   String predicateValueName)

Finds the QueryBuilder map entries that pertain to the parameterized predicate. This is helpful to find out what/which parameters are already present in a parameter map.

Parameters:

queryBuilderParams - the params to search through.

predicateName - the predicate name to find.

predicateValueName - the predicateName's predicate value to find. If null, it is set to the predicateName.

Returns:

a map that contains the QueryBuilder params (keys and values) that match the predicateName/predicateValueName param pair.
