Constructor Detail

AreaCodeMap

public AreaCodeMap()

Creates an empty AreaCodeMap. The default constructor is necessary for implementing Externalizable. The empty map could later be populated by readAreaCodeMap(java.util.SortedMap) or readExternal(java.io.ObjectInput).

Method Detail

readAreaCodeMap

public void readAreaCodeMap(java.util.SortedMap<java.lang.Integer,java.lang.String> sortedAreaCodeMap)

Creates an AreaCodeMap initialized with sortedAreaCodeMap. Note that the underlying implementation of this method is expensive thus should not be called by time-critical applications.

Parameters:

sortedAreaCodeMap - a map from phone number prefixes to descriptions of corresponding geographical areas, sorted in ascending order of the phone number prefixes as integers.

readExternal

public void readExternal(java.io.ObjectInput objectInput)
                  throws java.io.IOException

Supports Java Serialization.

Specified by:

readExternal in interface java.io.Externalizable

Throws:

java.io.IOException

writeExternal

public void writeExternal(java.io.ObjectOutput objectOutput)
                   throws java.io.IOException

Supports Java Serialization.

Specified by:

writeExternal in interface java.io.Externalizable

Throws:

java.io.IOException

toString

public java.lang.String toString()

Dumps the mappings contained in the area code map.

Overrides:

toString in class java.lang.Object
