m_capacity
int m_capacity
- The capacity of the map
m_size
int m_size
- The current number of elements of the map
m_keys
Object[] m_keys
- Array keeping the keys of the entries in the map. It is "synchrnized"
with the m_values array - the Nth position in both arrays correspond
to one and the same entry
m_values
Object[] m_values
- Array keeping the values of the entries in the map. It is "synchrnized"
with the m_keys array - the Nth position in both arrays correspond
to one and the same entry
g_akey
transient Object g_akey
serialVersionUID
static final long serialVersionUID
- Freeze the serialization UID.
nullKey
static transient Object nullKey
- the Object instance that will represent the NULL keys in the map
theKeysHere
public static transient HashMap theKeysHere
