Method Detail

getValue

public Object getValue(org.jbpm.formModeler.api.model.Field field,
                       String inputName,
                       Map parametersMap,
                       Map filesMap,
                       String desiredClassName,
                       Object previousValue)
                throws Exception

Read a parameter value (normally from a request), and translate it to an object with desired class (that must be one of the returned by this handler)

Returns:

a object with desired class

Throws:

NumericFieldHandler.EmptyNumberException

Exception

getTheValue

public Object getTheValue(org.jbpm.formModeler.api.model.Field field,
                          String[] paramValue,
                          String desiredClassName)
                   throws Exception

Throws:

Exception

getParamValue

public Map getParamValue(String inputName,
                         Object objectValue,
                         String pattern)

Determine the value as a parameter map for a given input value. This is like the inverse operation of getValue()

Parameters:

objectValue - Object value to represent

pattern - Pattern to apply if any

Returns:

a Map representing the parameter values expected inside a request that would cause the form to generate given object value as a result.

buildParamValue

protected String[] buildParamValue(Object value,
                                   String pattern)

Builds a correct paramValue for a given inputValue.

Parameters:

value - Object value to build its paramValue

pattern - pattern to apply if any

Returns:

a String[] with the paramValue on it or null if the value received is null

acceptsPropertyName

public boolean acceptsPropertyName(String propName)

getCompatibleClassNames

public String[] getCompatibleClassNames()

Determine the list of class types this field can generate. That is, normally, a field can generate multiple outputs (an input text can generate Strings, Integers, ...)

Returns:

the set of class types that can be generated by this handler.

isEmpty

public boolean isEmpty(Object value)
