Method Detail

add

void add(String key,
         Object obj)

Adds a request scoped variable. It is recommended that you prefixe the name of the key with the name of your class (for example : this.getClass().getName()), so it doesn't clash with other keys!

add

void add(Map<String,Object> variables)

Adds request scoped variables. It is recommended that you prefixe the name of the keys with the name of your class (for example : this.getClass().getName()), so they don't clash with other keys!

getAll

Map<String,Object> getAll()

Gets all the request scoped variables. The map is immutable.

get

Object get(String key)

Gets the specified request scoped variable.

get

<T> T get(String key,
          Class<T> clazz)

Gets the specified request scoped variable as the specified class.

Throws:

an - exception is the object is not of the specified class.

get

<T> T get(String key,
          com.google.inject.Key<T> typeKey)

Gets the specified request scoped variable as the specified Key.

Throws:

an - exception is the object is not of the specified Key.

getAsJsonObject

JsonObject getAsJsonObject(String key)

Gets the specified request scoped variable as JsonObject.

getAsString

String getAsString(String key)

Gets the specified request scoped variable as a String. toString will be called on the Object.

remove
