Method Detail

isPrioritized

public boolean isPrioritized()

Returns false (the default) if the runtimedoes not consider statement priority and preemptive instructions, or true to enable priority-based statement execution order.

Returns:

false by default to indicate unprioritized statement execution

setPrioritized

public void setPrioritized(boolean prioritized)

Set to false (the default) if the runtimedoes not consider statement priority and preemptive instructions, or true for enable priority-based statement execution order.

Parameters:

prioritized - false by default to indicate unprioritized statement execution

isFairlock

public boolean isFairlock()

Returns true for fair locking, false for unfair locks.

Returns:

fairness flag

setFairlock

public void setFairlock(boolean fairlock)

Set to true for fair locking, false for unfair locks.

Parameters:

fairlock - fairness flag

isDisableLocking

public boolean isDisableLocking()

Returns indicator whether statement-level locks are disabled. The default is false meaning statement-level locks are taken by default and depending on EPL optimizations. If set to true statement-level locks are never taken.

Returns:

indicator for statement-level locks

setDisableLocking

public void setDisableLocking(boolean disableLocking)

Set to true to indicate that statement-level locks are disabled. The default is false meaning statement-level locks are taken by default and depending on EPL optimizations. If set to true statement-level locks are never taken.

Parameters:

disableLocking - false to take statement-level locks as required, or true to disable statement-level locking

getFilterServiceProfile

public FilterServiceProfile getFilterServiceProfile()

Returns the filter service profile for tuning filtering operations.

Returns:

filter service profile

setFilterServiceProfile

public void setFilterServiceProfile(FilterServiceProfile filterServiceProfile)

Set the filter service profile for tuning filtering operations.

Parameters:

filterServiceProfile - filter service profile

getDeclaredExprValueCacheSize

public int getDeclaredExprValueCacheSize()

Returns the cache size for declared expression values

Returns:

value

setDeclaredExprValueCacheSize

public void setDeclaredExprValueCacheSize(int declaredExprValueCacheSize)

Sets the cache size for declared expression values

Parameters:

declaredExprValueCacheSize - value
