Method Summary

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

Method Detail

containsKey	back to summary
public boolean containsKey(byte[] key) throws IOException Returns true iff `key` is present.

get	back to summary
public byte[] get(byte[] key) throws IOException Gets the byte array associated with key, or none if this key is not present.

keys	back to summary
public IOByteArrayEnumeration keys() throws IOException 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.

put	back to summary
public void put(byte[] key, byte[] value) throws IOException 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`.

putNoReplace	back to summary
public boolean putNoReplace(byte[] key, byte[] value) throws IOException Associates the byte[] key with the byte[] value in the hash. Fails (and returns false) if key is already present in the map.

remove	back to summary
public boolean remove(byte[] key) throws IOException Removes the key, value pair whose key is the argument.
