示例1: doReceiveBlocking

/**
* First tries and perform a {@link org.openspaces.core.GigaSpace#readMultiple(Object,int,int)} using
* the provided template, configured maxEntries (defaults to <code>50</code>) and the configured fifoGroups (default to <code>false</code>).
* If no values are returned, will perform a blocking read operation using
* {@link org.openspaces.core.GigaSpace#read(Object,long,int)}.
*
* <p>Read operations are performed under an exclusive read lock which mimics the similar behavior
* as take without actually taking the entry from the space.
