## com.tangosol.util
Class SegmentedHashMap.GetEntryAction

    java.lang.Object
      com.tangosol.util.SegmentedHashMap.GetEntryAction

All Implemented Interfaces:
  SegmentedHashMap.EntryAction

Enclosing class:
  SegmentedHashMap

    protected class SegmentedHashMap.GetEntryAction

extends java.lang.Object
implements SegmentedHashMap.EntryAction

Action support for getEntryInternal. The action performs an Entry lookup by key and is not required to run while holding segment locks.

The context object for a GetEntryAction is either `Boolean.TRUE` or `Boolean.FALSE` indicating whether or not to return synthetic entries.

The result of invoking a GetEntryAction is the (possibly synthetic) Entry corresponding to a given key, `null` if no matching Entry is found, or `NO_VALUE` indicating that a concurrent resize occurred, and the operation must be repeated.

Constructor Summary
`protected` | `SegmentedHashMap.GetEntryAction()`

Method Summary
`java.lang.Object` | `invokeFound(java.lang.Object oKey, java.lang.Object oContext, SegmentedHashMap.Entry[] aeBucket, int nBucket, SegmentedHashMap.Entry entryPrev, SegmentedHashMap.Entry entryCur)` Invoke some action, holding the segment lock, when a matching Entry is found.
`java.lang.Object` | `invokeNotFound(java.lang.Object oKey, java.lang.Object oContext, SegmentedHashMap.Entry[] aeBucket, int nBucket)` Invoke some action, holding the segment lock, when no matching Entry is found.

  Invoke some action, holding the segment lock, when a matching Entry is found.

  Specified by:
    `invokeFound` in interface `SegmentedHashMap.EntryAction`
  Parameters:

    `oContext` - opaque context specific to the action
    `aeBucket` - the bucket array
    `nBucket` - the index into the bucket array
    `entryPrev` - the Entry object immediately preceding the Entry that was found, or null
    `entryCur` - the Entry object that was found
  Returns:
    an opaque result value

### invokeNotFound

    public java.lang.Object invokeNotFound(java.lang.Object oKey,
                                           java.lang.Object oContext,
                                           SegmentedHashMap.Entry[] aeBucket,
                                           int nBucket)

  Invoke some action, holding the segment lock, when no matching Entry is found.

  Specified by:
    `invokeNotFound` in interface `SegmentedHashMap.EntryAction`
  Parameters:
    `oKey` - the key to which the action is applied
    `oContext` - opaque context specific to the action
