Method Detail

add

protected boolean add(java.lang.Object oKey)

Add the specified key to the Bundle.

Note: a call to this method must be externally synchronized for this Bundle object.

Parameters:

oKey - the key to add to this Bundle

Returns:

true if this Bundle was empty prior to this call

addAll

protected boolean addAll(java.util.Collection colKeys)

Add the specified collection of keys to the Bundle.

Note: a call to this method must be externally synchronized for this Bundle object.

Parameters:

colKeys - the collection of keys to add to this Bundle

Returns:

true if this Bundle was empty prior to this call

process

protected java.lang.Object process(boolean fBurst,
                                   java.lang.Object oKey)

Process the specified key according to this Bundle state.

Parameters:

fBurst - true if this thread is supposed to perform an actual bundled operation (burst); false otherwise

oKey - the key to process

Returns:

an execution result according to the caller's contract

processAll

protected java.util.Map processAll(boolean fBurst,
                                   java.util.Collection colKeys)

Process the specified key collection according to this Bundle state.

Parameters:

fBurst - true if this thread is supposed to perform an actual bundled operation (burst); false otherwise

colKeys - the collection of keys to process

Returns:

an execution result according to the caller's contract

getBundleSize

protected int getBundleSize()

Obtain this bundle size. The return value should be expressed in the same units as the value returned by the getSizeThreshold method.

Overrides:

getBundleSize in class AbstractBundler.Bundle

Returns:

the bundle size

ensureResults

protected void ensureResults()

Obtain results of the bundled requests. This method should be implemented by concrete Bundle implementations using the most efficient mechanism.

Specified by:

ensureResults in class AbstractBundler.Bundle

releaseThread

protected boolean releaseThread()

Release all bundle resources associated with the current thread.

Overrides:

releaseThread in class AbstractBundler.Bundle

Returns:

true iff all entered threads have released
