Constructor Detail

State

public State()

Constructor with default capacity.

State

public State(boolean threadSafe)

Constructor with default capacity, optionally thread-safe.

Parameters:

threadSafe - if true, then a ConcurrentHashMap is used

State

public State(int size)

Constructor for a given default size.

public State(int size,
     boolean threadSafe)

Constructor for a given default size, optionally thread-safe.

Parameters:

threadSafe - if true, then a ConcurrentHashMap is used

Method Detail

size

public int size()

Gets the number of elements.

isEmpty

public boolean isEmpty()

Checks if the state is empty.

get

public Serializable get(Object key)

Gets a value for a key, or null if the key is not present.

putInternal

public void putInternal(String key,
               Serializable value)

Sets a key/value.

put

public void put(String key,
       Serializable value)

Sets a key/value, dealing with deltas.

remove

public Serializable remove(Object key)

Removes the mapping for a key.

Returns:

the previous value associated with the key, or null if there was no mapping for the key

keySet

public Set<String> keySet()

Gets the key set. IT MUST NOT BE MODIFIED.

containsKey

public boolean containsKey(Object key)

Checks if there is a mapping for the given key.

entrySet

public Set<Map.Entry<String,Serializable>> entrySet()

Gets the entry set. IT MUST NOT BE MODIFIED.

toString

public String toString()

Overridden to display Calendars and arrays better, and truncate long strings and arrays.

Also displays some keys first (ecm:id, ecm:name, ecm:primaryType)
