Method Detail

beforeQuery

public void beforeQuery(QueryExecutionInfo execInfo)

Description copied from interface: ProxyExecutionListener

Called before executing a query (Batch.execute() or Statement.execute()).

Note: this callback is called when the publisher, result of the execute(), is being subscribed. Not at the time of execute() is called,

Specified by:

beforeQuery in interface ProxyExecutionListener

Parameters:

execInfo - query execution context

afterQuery

public void afterQuery(QueryExecutionInfo execInfo)

Description copied from interface: ProxyExecutionListener

Called after executing a query (Batch.execute() or Statement.execute()).

The callback order is:

• ProxyExecutionListener.beforeQuery(QueryExecutionInfo)
• ProxyExecutionListener.eachQueryResult(QueryExecutionInfo) for 1st result
• ProxyExecutionListener.eachQueryResult(QueryExecutionInfo) for 2nd result
• ...
• ProxyExecutionListener.eachQueryResult(QueryExecutionInfo) for Nth result
• ProxyExecutionListener.afterQuery(QueryExecutionInfo)

QueryExecutionInfo.getExecuteDuration() is available in this callback and it holds the duration since ProxyExecutionListener.beforeQuery(QueryExecutionInfo).

Note: this callback is called when the publisher, result of the execute(), is being subscribed. Not at the time of execute() is called,

Specified by:

afterQuery in interface ProxyExecutionListener

Parameters:

execInfo - query execution context

eachQueryResult

public void eachQueryResult(QueryExecutionInfo execInfo)

Description copied from interface: ProxyExecutionListener

Called on processing each query Result.

While processing query results Result, this callback is called per result.

QueryExecutionInfo.getCurrentMappedResult() contains the mapped result.

Specified by:

eachQueryResult in interface ProxyExecutionListener

Parameters:

execInfo - query execution context

beforeMethod

public void beforeMethod(MethodExecutionInfo executionInfo)

Description copied from interface: ProxyExecutionListener

Called before every invocation of methods.

Specified by:

beforeMethod in interface ProxyExecutionListener

Parameters:

executionInfo - method execution context

afterMethod

public void afterMethod(MethodExecutionInfo executionInfo)

Description copied from interface: ProxyExecutionListener

Called after every invocation of methods.

Specified by:

afterMethod in interface ProxyExecutionListener

Parameters:

executionInfo - method execution context

getEachQueryResultExecutionInfo

public QueryExecutionInfo getEachQueryResultExecutionInfo()

Get the last used QueryExecutionInfo in ProxyExecutionListener.eachQueryResult(QueryExecutionInfo).

Returns:

last used QueryExecutionInfo. Can be null if not invoked yet.

public MethodExecutionInfo getBeforeMethodExecutionInfo()

Get the last used MethodExecutionInfo in ProxyExecutionListener.beforeMethod(MethodExecutionInfo).

Returns:

last used MethodExecutionInfo. Can be null if not invoked yet.

getAfterMethodExecutionInfo

public MethodExecutionInfo getAfterMethodExecutionInfo()

Get the last used MethodExecutionInfo in ProxyExecutionListener.afterMethod(MethodExecutionInfo).

Returns:

last used MethodExecutionInfo. Can be null if not invoked yet.
