Constructor Detail

ValueMapDecorator

public ValueMapDecorator(java.util.Map<java.lang.String,java.lang.Object> base)

Creates a new wrapper around a given map.

Parameters:

base - wrapped object

Method Detail

get

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

Get a named property and convert it into the given type.

Specified by:

get in interface ValueMap

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)

Get a named property and convert it into the given type.

Specified by:

get in interface ValueMap

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. If this is null any existing propert is not converted.

Returns:

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