Method Summary

Modifier and Type	Method and Description
long	getDelayMillis(com.tangosol.config.expression.ParameterResolver resolver) Specifies the maximum amount of time that individual execution requests are allowed to be deferred for a purpose of "bundling" them and passing into a corresponding bulk operation.
String	getOperationName(com.tangosol.config.expression.ParameterResolver resolver) Return the operation name for which calls performed concurrently on multiple threads are "bundled" into a functionally analogous "bulk" operation that takes a collection of arguments instead of a single one.
int	getPreferredSize(com.tangosol.config.expression.ParameterResolver resolver) Return the bundle size threshold.
int	getThreadThreshold(com.tangosol.config.expression.ParameterResolver resolver) Return the minimum number of threads that must be concurrently executing individual(non-bundled) requests for the bundler to switch from a pass-through to a bundling mode.
boolean	isAutoAdjust(com.tangosol.config.expression.ParameterResolver resolver) Return true if the auto adjustment of the preferred size value (based on the run-time statistics) is allowed.
void	setAutoAdjust(com.tangosol.config.expression.Expression<Boolean> expr) Set the flag to auto adjust the preferred size value, based on the run-time statistics.
void	setDelayMillis(com.tangosol.config.expression.Expression<Millis> expr) Set the write delay.
void	setOperationName(com.tangosol.config.expression.Expression<String> expr) Set the operation name for which calls performed concurrently on multiple threads are bundled.
void	setPreferredSize(com.tangosol.config.expression.Expression<Integer> expr) Set the bundle size threshold.
void	setThreadThreshold(com.tangosol.config.expression.Expression<Integer> expr) Set the thread threshold.
protected void	validate(com.tangosol.config.expression.ParameterResolver resolver) Validate the bundle configuration.

Method Detail

isAutoAdjust

public boolean isAutoAdjust(com.tangosol.config.expression.ParameterResolver resolver)

Return true if the auto adjustment of the preferred size value (based on the run-time statistics) is allowed.

Parameters:

resolver - the ParameterResolver

Returns:

true if auto-adjust is enabled

setAutoAdjust

@Injectable
public void setAutoAdjust(com.tangosol.config.expression.Expression<Boolean> expr)

Set the flag to auto adjust the preferred size value, based on the run-time statistics.

Parameters:

expr - true if auto adjustment is enabled

getDelayMillis

public long getDelayMillis(com.tangosol.config.expression.ParameterResolver resolver)

Specifies the maximum amount of time that individual execution requests are allowed to be deferred for a purpose of "bundling" them and passing into a corresponding bulk operation. If the preferred-size threshold is reached before the specified delay, the bundle is processed immediately.

Parameters:

resolver - the ParameterResolver

Returns:

the write delay

setDelayMillis

@Injectable
public void setDelayMillis(com.tangosol.config.expression.Expression<Millis> expr)

Set the write delay.

Parameters:

expr - the write delay

getOperationName

public String getOperationName(com.tangosol.config.expression.ParameterResolver resolver)

Return the operation name for which calls performed concurrently on multiple threads are "bundled" into a functionally analogous "bulk" operation that takes a collection of arguments instead of a single one.

Parameters:

resolver - the ParameterResolver

Returns:

the operation name

setOperationName

@Injectable
public void setOperationName(com.tangosol.config.expression.Expression<String> expr)

Set the operation name for which calls performed concurrently on multiple threads are bundled.

Parameters:

expr - the operation name

getPreferredSize

public int getPreferredSize(com.tangosol.config.expression.ParameterResolver resolver)

Return the bundle size threshold. When a bundle size reaches this value, the corresponding "bulk" operation is invoked immediately. This value is measured in context-specific units.

Parameters:

resolver - the ParameterResolver

Returns:

the size threshold

setPreferredSize

@Injectable
public void setPreferredSize(com.tangosol.config.expression.Expression<Integer> expr)

Set the bundle size threshold.

Parameters:

expr - the size threshold

getThreadThreshold

public int getThreadThreshold(com.tangosol.config.expression.ParameterResolver resolver)

Return the minimum number of threads that must be concurrently executing individual(non-bundled) requests for the bundler to switch from a pass-through to a bundling mode.

Parameters:

resolver - the ParameterResolver

Returns:

the thread threshold

setThreadThreshold

@Injectable
public void setThreadThreshold(com.tangosol.config.expression.Expression<Integer> expr)

Set the thread threshold.

Parameters:

expr - the thread threshold

validate

protected void validate(com.tangosol.config.expression.ParameterResolver resolver)

Validate the bundle configuration.

Parameters:

resolver - the ParameterResolver for resolving expressions and runtime parameters
