Constructor Detail

MultiBinaryLongMap.AbstractDelegateBinaryLongMap

public MultiBinaryLongMap.AbstractDelegateBinaryLongMap(BinaryLongMap blm,
                                                        MultiBinaryLongMap.LongStorage store,
                                                        int iIndex)

Construct an AbstractDelegateBinaryLongMap based on the specified key tree, long storage, and storage index.

Parameters:

blm - the BinaryLongMap holding the keys

store - the long storage

iIndex - the storage index

Method Detail

get

public long get(Binary binKey)

Find the specified key in the map and return the value associated with it.

Specified by:

get in interface BinaryLongMap

Parameters:

binKey - a Binary key

Returns:

the value associated with the specified key, or 0L if the specified key is not in the map

internKeys

public void internKeys(java.lang.Object o)

Internal opaque method: De-duplicate keys.

Specified by:

internKeys in interface BinaryLongMap

Parameters:

o - some implementation-specific object

keys

public java.util.Iterator keys()

Obtain an iterator of the keys stored in the map.

Specified by:

keys in interface BinaryLongMap

Returns:

an Iterator of Binary keys

keys

public java.util.Iterator keys(com.oracle.common.base.Predicate predicate)

Obtain an iterator of the keys stored in the map whose corresponding Entry matches the passed Predicate<Entry>.

The entry passed to the predicate should be treated as read-only, and any attempt to modify the entry may have undefined behavior and/or throw an Exception. Modifications to entries should instead be performed using an BinaryLongMap.EntryVisitor via the BinaryLongMap.visit(com.tangosol.util.Binary, com.tangosol.util.BinaryLongMap.EntryVisitor) or BinaryLongMap.visitAll(com.tangosol.util.BinaryLongMap.EntryVisitor) methods.

Specified by:

keys in interface BinaryLongMap

Parameters:

predicate - a Predicate<Entry> to apply to each Entry

Returns:

an Iterator of Binary keys

visit

public void visit(Binary binKey,
                  BinaryLongMap.EntryVisitor visitor)

Apply the specified visitor to the entry associated with the specified key, if the entry exists or may be added. The visited entry may or may not logically exist in the BinaryLongMap (e.g. it may be associated with a value of 0L) but is guaranteed to be safe to be added or removed (via BinaryLongMap.Entry.setValue(long)).

Specified by:

visit in interface BinaryLongMap

Parameters:

binKey - the key to visit

visitor - the visitor to apply

visitAll

public void visitAll(BinaryLongMap.EntryVisitor visitor)

Apply the specified visitor to all entries in the BinaryLongMap.

Specified by:

visitAll in interface BinaryLongMap

Parameters:

visitor - the visitor to apply

getIndex

protected int getIndex()

Determine the index into the LongStorage that this DelegatingBinaryLongMap is assigned.

Returns:

the index into the LongStorage

setIndex

protected void setIndex(int iIndex)

Set the index into the LongStorage assigned to this DelegatingBinaryLongMap.

Parameters:

iIndex - the index into the LongStorage

getSlot

protected int getSlot(Binary binKey)

Return the slot index associated with the specified key.

Parameters:

binKey - the key to return the slot for

Returns:

the slot index associated with the specified key

updateValue

protected boolean updateValue(int iSlot,
                              long lValueOld,
                              long lValueNew,
                              boolean fForce)

Associate the passed value with the specified key, optionally performing the operation only if the value currently associated with the key matches the passed "old" value.

Parameters:

iSlot - the slot whose value to update

lValueOld - the value that is assumed to be currently associated with the key

lValueNew - the value to associate with the key

fForce - true iff the value should be associated regardless of the old value

Returns:

if fForce is true, then the return value is true iff an item was added as the result of this operation; if fForce is false, then the return value is true iff the operation affected a change to the BinaryLongMap
