Interface UninterruptibleHashtable

All Known Implementing Classes:

AbstractUninterruptibleHashtable

public interface UninterruptibleHashtable

Common interface for all uninterruptible hashtable implementations. Please note that we don't use generics as this sometimes breaks the Uninterruptible annotation when ECJ is used for compiling the Java sources.

Method Summary

Modifier and Type	Method and Description
void	clear() Clear all entries from map.
UninterruptibleEntry	get(UninterruptibleEntry valueOnStack) Returns the matching value for valueOnStack from the hashtable.
UninterruptibleEntry	getOrPut(UninterruptibleEntry valueOnStack) If the hashtable contains an existing entry that matches valueOnStack, then this existing entry will be returned and no value will be inserted.
int	getSize() Gets the number of entries that are in the hashtable.
UninterruptibleEntry[]	getTable() Returns the internal array of the hashtable.
boolean	putIfAbsent(UninterruptibleEntry valueOnStack) Tries to insert valueOnStack into the hashtable.
void	teardown() Teardown hashtable.

Method Detail

getSize

int getSize()

Gets the number of entries that are in the hashtable.

getTable

UninterruptibleEntry[] getTable()

Returns the internal array of the hashtable.

get

UninterruptibleEntry get(UninterruptibleEntry valueOnStack)

Returns the matching value for valueOnStack from the hashtable. If there is no matching value in the hashtable, a null pointer is returned.

putIfAbsent

boolean putIfAbsent(UninterruptibleEntry valueOnStack)

Tries to insert valueOnStack into the hashtable. Returns false if there was already a matching entry in the hashtable or if an error occurred while insert the entry. Returns true if the entry was inserted successfully.

getOrPut

UninterruptibleEntry getOrPut(UninterruptibleEntry valueOnStack)

If the hashtable contains an existing entry that matches valueOnStack, then this existing entry will be returned and no value will be inserted. If there wasn't already a matching entry, this method tries to create and insert a new entry hashtable. If an error occurred while inserting the entry, a null pointer is returned instead.

clear

void clear()

Clear all entries from map.

teardown

void teardown()

Teardown hashtable.
