org.springframework.beans.propertyeditors.CustomMapEditor
| Constructor Summary | |
| public | CustomMapEditor(Class mapType)
Create a new CustomMapEditor for the given target type,
keeping an incoming null as-is. | | public | CustomMapEditor(Class mapType, boolean nullAsEmptyMap)
Create a new CustomMapEditor for the given target type. |
| Method Summary | |
| protected boolean | alwaysCreateNewMap()
Return whether to always create a new Map,
even if the type of the passed-in Map already matches. | | protected Object | convertKey(Object key)
Hook to convert each encountered Map key.
The default implementation simply returns the passed-in key as-is.
Can be overridden to perform conversion of certain keys,
for example from String to Integer.
Only called if actually creating a new Map!
This is by default not the case if the type of the passed-in Map
already matches. | | protected Object | convertValue(Object value)
Hook to convert each encountered Map value.
The default implementation simply returns the passed-in value as-is.
Can be overridden to perform conversion of certain values,
for example from String to Integer.
Only called if actually creating a new Map!
This is by default not the case if the type of the passed-in Map
already matches. | | protected Map | createMap(Class mapType, int initialCapacity)
Create a Map of the given type, with the given
initial capacity (if supported by the Map type). | | public String | getAsText()
This implementation returns null to indicate that
there is no appropriate text representation. | | public void | setAsText(String text)
Convert the given text value to a Map with a single element. | | public void | setValue(Object value)
Convert the given value to a Map of the target type. |
| CustomMapEditor | | public CustomMapEditor(Class mapType, boolean nullAsEmptyMap)(Code) | | Create a new CustomMapEditor for the given target type.
If the incoming value is of the given type, it will be used as-is.
If it is a different Map type or an array, it will be converted
to a default implementation of the given Map type.
If the value is anything else, a target Map with that single
value will be created.
The default Map implementations are: ArrayList for List,
TreeSet for SortedSet, and LinkedHashSet or HashSet for Set.
Parameters:
mapType - the target type, which needs to be asub-interface of Map or a concrete Map class
Parameters:
nullAsEmptyMap - ap whether to convert an incoming nullvalue to an empty Map (of the appropriate type)

| alwaysCreateNewMap | | protected boolean alwaysCreateNewMap()(Code) | | Return whether to always create a new Map,
even if the type of the passed-in Map already matches.
Default is "false"; can be overridden to enforce creation of a
new Map, for example to convert elements in any case.

| convertKey | | protected Object convertKey(Object key)(Code) | | Hook to convert each encountered Map key.
The default implementation simply returns the passed-in key as-is.
Can be overridden to perform conversion of certain keys,
for example from String to Integer.
Only called if actually creating a new Map!
This is by default not the case if the type of the passed-in Map
already matches. Override
CustomMapEditor.alwaysCreateNewMap() to
enforce creating a new Map in every case.
Parameters:
key - the source key the key to be used in the target Map
See Also: CustomMapEditor.alwaysCreateNewMap |
| convertValue | | protected Object convertValue(Object value)(Code) | | Hook to convert each encountered Map value.
The default implementation simply returns the passed-in value as-is.
Can be overridden to perform conversion of certain values,
for example from String to Integer.
Only called if actually creating a new Map!
This is by default not the case if the type of the passed-in Map
already matches. Override
CustomMapEditor.alwaysCreateNewMap() to
enforce creating a new Map in every case.
Parameters:
value - the source value the value to be used in the target Map

| createMap | | protected Map createMap(Class mapType, int initialCapacity)(Code) | | Create a Map of the given type, with the given
initial capacity (if supported by the Map type).
Parameters:
mapType - a sub-interface of Map
Parameters:
initialCapacity - the initial capacity the new Map instance |
| getAsText | | public String getAsText()(Code) | | This implementation returns null to indicate that
there is no appropriate text representation.
|
| setValue | | public void setValue(Object value)(Code) | | Convert the given value to a Map of the target type.
