Method Detail

convertListOfMapsToObjects

public <T> List<T> convertListOfMapsToObjects(List<Map> list,
                                     Class<T> componentType)

This converts a list of maps to objects. I always forget that this exists. I need to remember.

Type Parameters:

T - generics

Parameters:

list - the input list

Returns:

a new list

fromMap

public <T> T fromMap(Map<String,Object> map,
            Class<T> cls)

fromMap converts a map into a java object

Type Parameters:

T - map to create teh object from.

Parameters:

map - map to create the object from.

cls - class type of new object

Returns:

new object of type cls

fromList

public <T> T fromList(List<?> argList,
             Class<T> clazz)

Convert an item from a list into a class using the classes constructor. REFACTOR: Can't this just be from collection? REFACTOR

Type Parameters:

T - generics

Parameters:

argList - list if arguments

clazz - the type of the object we are creating

Returns:

the new object that we just created.

fromValueMap

public Object fromValueMap(Map<String,Value> valueMap)

Creates an object from a value map. This does some special handling to take advantage of us using the value map so it avoids creating a bunch of array objects and collections. Things you have to worry about when writing a high-speed JSON serializer.

Returns:

new object from value map

fromValueMap

public <T> T fromValueMap(Map<String,Value> valueMap,
                 Class<T> cls)

Creates an object from a value map. This does some special handling to take advantage of us using the value map so it avoids creating a bunch of array objects and collections. Things you have to worry about when writing a high-speed JSON serializer.

Parameters:

cls - the new type

Returns:

new object from value map

fromMap

public Object fromMap(Map<String,Object> map)

fromMap converts a map into a Java object. This version will see if there is a class parameter in the map, and dies if there is not.

Parameters:

map - map to create the object from.

Returns:

new object

toMap

public Map<String,Object> toMap(Object object)

This could be refactored to use core.Type class and it would run faster. Converts an object into a map

Parameters:

object - the object that we want to convert

Returns:

map map representation of the object

toListOfMaps

public List<Map<String,Object>> toListOfMaps(Collection<?> collection)

Creates a list of maps from a list of class instances.

Parameters:

collection - the collection we are coercing into a field value

Returns:

the return value.

toList

public List<?> toList(Object object)

Convert an object to a list.

Parameters:

object - the object we want to convert to a list

Returns:

new list from an object
