public ModelImpl()

Method Detail

getFieldNames

public String[] getFieldNames()

Returns the complete set of properties associated with the model instance.

Specified by:

getFieldNames in interface Model

Returns:

a string array

hasField

public boolean hasField(String fieldName)

Returns true if a value is associated with the specified field name, false otherwise.

Specified by:

hasField in interface Model

Parameters:

fieldName - name of field to look up

Returns:

a boolean value

getField

public Object getField(String fieldName)

Returns the value of the specified field as an Object.

Specified by:

getField in interface Model

Parameters:

fieldName - name of field whose value is to be returned

Returns:

an object associated with fieldName

getFieldAsMap

public Map getFieldAsMap(String fieldName)

Returns the value of the specified field as a Map. Equivalent to (Map) getField(fieldName), hence this method will throw a ClassCastException if the field does not implement Map.

Specified by:

getFieldAsMap in interface Model

Parameters:

fieldName - name of field whose value is to be returned

Returns:

a map associated with fieldName

See Also:

ClassCastException

getFieldAsList

public List getFieldAsList(String fieldName)

Returns the value of the specified field as a List. Equivalent to (List) getField(fieldName), hence this method will throw a ClassCastException if the field does not implement List.

Specified by:

getFieldAsList in interface Model

Parameters:

fieldName - name of field whose value is to be returned

Returns:

a list associated with fieldName

See Also:

ClassCastException

getFieldAsString

public String getFieldAsString(String fieldName)

Returns the value of the specified field as a String. Equivalent to (String) getField(fieldName), hence this method will throw a ClassCastException if the field is not of type String.

Specified by:

getFieldAsString in interface Model

Parameters:

fieldName - name of field whose value is to be returned

Returns:

a string associated with fieldName

See Also:

ClassCastException

isFieldMultikeyed

public boolean isFieldMultikeyed(String fieldName)

Returns true if the value of the specified field implements Map, false otherwise.

Specified by:

isFieldMultikeyed in interface Model

Parameters:

fieldName - name of field to look up

Returns:

a boolean value

isFieldMultivalued

public boolean isFieldMultivalued(String fieldName)

Returns true if the value of the specified field implements List, false otherwise.

Specified by:

isFieldMultivalued in interface Model

Parameters:

fieldName - name of field to look up

Returns:

a boolean value

setField

public void setField(String fieldName,
                     Object value)

Sets the value of the specified field to the passed Object.

Specified by:

setField in interface Model

Parameters:

fieldName - name of field to set

value - object to associate with passed field name

addToListField

public void addToListField(String fieldName,
                           Object item)

Adds the passed Object to the list field with the specified name.

Specified by:

addToListField in interface Model

Parameters:

fieldName - name of list field for which the passed item should be added

item - item to add

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a property change event listener to this model

Specified by:

addPropertyChangeListener in interface Model

Parameters:

listener - The listener to be added

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a property change event listener which was added to this model.

Specified by:

removePropertyChangeListener in interface Model

Parameters:

listener - The listener to be removed.

findPropertyChangeListeners

public PropertyChangeListener[] findPropertyChangeListeners()

Gets the property change listeners registered and associated with this property change listener. If this property change has no listeners registered, a zero-length array is returned.

Specified by:

findPropertyChangeListeners in interface Model

Returns:

an array of listeners
