Class BulkEditValueMap

java.lang.Object

com.adobe.granite.ui.components.BulkEditValueMap

All Implemented Interfaces:

java.util.Map<java.lang.String,java.lang.Object>, ValueMap

public class BulkEditValueMap
extends java.lang.Object
implements ValueMap

BulkEditValueMap is a ValueMap specific to the needs of Bulk Editing. It is aimed at merging the given Resources' ValueMaps.

Please not that the merge is actually "virtual" since under the hood the ValueMap will always be empty. In other words, get(Object key) performs an on-demand merge for the passed key.

In addition to providing the actual (merged) value for a given key, this specific ValueMap can also tell if a given key has a mixed value using #get(key + Field.IS_MIXED_SUFFIX).

public BulkEditValueMap(java.util.List<Resource> resources)

Method Detail

get

public java.lang.Object get(java.lang.Object key)

Retrieves the merged value for the passed key. Calling #get(key + Field.IS_MIXED_SUFFIX) returns true if the value is mixed; false otherwise. If the value is non-existent null is returned.

Specified by:

get in interface java.util.Map<java.lang.String,java.lang.Object>

Parameters:

key - The key of the value to retrieve.

Returns:

The merged value for the passed key; or a boolean telling if the value is mixed or not (if the key ends with Field.IS_MIXED_SUFFIX).

get

public <T> T get(java.lang.String name,
                 java.lang.Class<T> type)

Description copied from interface: ValueMap

Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return null in this case.

Specified by:

get in interface ValueMap

Type Parameters:

T - The class of the type

Parameters:

name - The name of the property

type - The class of the type

Returns:

Return named value converted to type T or null if non existing or can't be converted.

get

public <T> T get(java.lang.String name,
                 T defaultValue)

Description copied from interface: ValueMap

Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return the default value in this case.

Implementation hint: In the past it was allowed to call this with a 2nd parameter being null. Therefore all implementations should internally call Map.get(Object) when the 2nd parameter has value null.

Specified by:

get in interface ValueMap

Type Parameters:

T - The expected type

Parameters:

name - The name of the property

defaultValue - The default value to use if the named property does not exist or cannot be converted to the requested type. The default value is also used to define the type to convert the value to. Must not be null. If you want to return null by default rather rely on ValueMap.get(String, Class).

Returns:

Return named value converted to type T or the default value if non existing or can't be converted.
