CheckBoxFieldHandler()

Method Summary

String[]	getCompatibleClassNames() Determine the list of class types this field can generate.
Map	getParamValue(String inputName, Object objectValue, String pattern) Determine the value as a parameter map for a given input value.
Object	getValue(org.jbpm.formModeler.api.model.Field field, String inputName, Map parametersMap, Map filesMap, String desiredClassName, Object previousValue) 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)

Constant Field Values

Constructor Detail

CheckBoxFieldHandler

public CheckBoxFieldHandler()

Method Detail

isEmpty

public boolean isEmpty(Object value)

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.

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:

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.
