FieldHandler

public class CharacterFieldHandler
extends DefaultFieldHandler

Handler for char/Character input

Constructor Summary

CharacterFieldHandler()

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)

Constructor Detail

CharacterFieldHandler

public CharacterFieldHandler()

Method Detail

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.

isEmpty

public boolean isEmpty(Object value)
