Method Detail

getAs

public <T> T getAs(Class<T> targetType,
          String key,
          T defaultValue)

Gets the value to which the specified key is mapped, and coerces that value to the specified target type. If this map contains no mapping for the key, a specified default value is returned instead.

Type Parameters:

T - the target type

Parameters:

targetType - the type to coerce the retrieved value to

key - the key of the value to retrieve

defaultValue - the default value

Returns:

the value, coerced to targetType, to which key is mapped or defaultValue

See Also:

#getAs(Class, String)

requireAs

public <T> T requireAs(Class<T> targetType,
              String key)

Gets the value to which the specified key is mapped, and coerces that value to a specified type. If this map contains no mapping for the key, or the key is mapped to a null value, a user-friendly exception is thrown.

Type Parameters:

T - the target type

Parameters:

targetType - the type to coerce the retrieved value to

key - the key of the value to retrieve

Returns:

the value, coerced to valueType, to which key is mapped
