IOByteArrayMap

public interface ByteArrayMap
extends IOByteArrayMap

Method Summary

Modifier and Type	Method and Description
boolean	containsKey(byte[] key) Returns true iff key is present.
byte[]	get(byte[] key) Gets the byte array associated with key, or none if this key is not present.
IOByteArrayEnumeration	keys() Returns a list of all keys in the hash, provided no inserts or deletes are made while the Enumeration is untraversed.
ByteArrayEnumeration	mkeys() returns a simple Enumeration (that does not throw IOExceptions)
void	put(byte[] key, byte[] value) Associates the byte[] key with the byte[] value in the hash.
boolean	putNoReplace(byte[] key, byte[] value) Associates the byte[] key with the byte[] value in the hash.
boolean	remove(byte[] key) Removes the key, value pair whose key is the argument.

Method Detail

get

byte[] get(byte[] key)

Gets the byte array associated with key, or none if this key is not present.

Specified by:

get in interface IOByteArrayMap

put

void put(byte[] key,
         byte[] value)

Associates the byte[] key with the byte[] value in the hash. If key is already present in the map, the old value associated with it is replaced by value.

Specified by:

put in interface IOByteArrayMap

putNoReplace

boolean putNoReplace(byte[] key,
                     byte[] value)

Associates the byte[] key with the byte[] value in the hash. Fails (and returns false) if key is already present in the map.

Specified by:

putNoReplace in interface IOByteArrayMap

remove

boolean remove(byte[] key)

Removes the key, value pair whose key is the argument.

Specified by:

remove in interface IOByteArrayMap

containsKey

boolean containsKey(byte[] key)

Returns true iff key is present.

Specified by:

containsKey in interface IOByteArrayMap

keys

IOByteArrayEnumeration keys()

Returns a list of all keys in the hash, provided no inserts or deletes are made while the Enumeration is untraversed. If inserts or deletes are made. the behavior is undefined.

Specified by:

keys in interface IOByteArrayMap

mkeys

ByteArrayEnumeration mkeys()

returns a simple Enumeration (that does not throw IOExceptions)
