Constructor Details

PhonePrefixMap

public PhonePrefixMap()

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

Method Details

readPhonePrefixMap

public void readPhonePrefixMap(SortedMap<Integer,String> sortedPhonePrefixMap)

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

Parameters:

sortedPhonePrefixMap - a map from phone number prefixes to descriptions of those prefixes sorted in ascending order of the phone number prefixes as integers.

readExternal

public void readExternal(ObjectInput objectInput)
                  throws IOException

Supports Java Serialization.

Specified by:

readExternal in interface Externalizable

Throws:

IOException

writeExternal

public void writeExternal(ObjectOutput objectOutput)
                   throws IOException

Supports Java Serialization.

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

lookup

public String lookup(Phonenumber.PhoneNumber number)

As per lookup(long), but receives the number as a PhoneNumber instead of a long.

Parameters:

number - the phone number to look up

Returns:

the description corresponding to the prefix that best matches this phone number

toString

public String toString()

Dumps the mappings contained in the phone prefix map.

Overrides:

toString in class Object
