getMetadata

public QueryMetadata getMetadata()

Description copied from interface: SQLListenerContext

Return the underlying query metadata

Specified by:

getMetadata in interface SQLListenerContext

Returns:

the underlying query metadata

getEntity

public RelationalPath<?> getEntity()

Description copied from interface: SQLListenerContext

Return the underlying entity affected

NOTE : This can be null depending on the stage of the query execution

Specified by:

getEntity in interface SQLListenerContext

Returns:

the underlying entity affected

getSQL

public String getSQL()

Description copied from interface: SQLListenerContext

Return the underlying sql or first in a batch query

NOTE : This can be null depending on the stage of the query execution

Specified by:

getSQL in interface SQLListenerContext

Returns:

the underlying sql or first in a batch query

getSQLStatements

public Collection<String> getSQLStatements()

Description copied from interface: SQLListenerContext

Return the underlying sql collection if the query is a batch query

NOTE : This can be empty depending on the stage of the query execution

Specified by:

getSQLStatements in interface SQLListenerContext

Returns:

the underlying sql collection if the query is a batch query

getException

public Exception getException()

Description copied from interface: SQLListenerContext

Return the underlying exception that has happened during query execution

NOTE : This can be null depending on whether an exception occurred

Specified by:

getException in interface SQLListenerContext

Returns:

the underlying exception that has happened during query execution

getConnection

public Connection getConnection()

Description copied from interface: SQLListenerContext

Return the underlying connection if there is one

NOTE : This can be null depending on the stage of the query execution

Specified by:

getConnection in interface SQLListenerContext

Returns:

the underlying connection if there is one

getPreparedStatements

public Collection<PreparedStatement> getPreparedStatements()

Description copied from interface: SQLListenerContext

Return the underlying set of prepared statements

NOTE : This can be empty depending on the stage of the query execution

Specified by:

getPreparedStatements in interface SQLListenerContext

Returns:

the underlying set of prepared statements

getPreparedStatement

public PreparedStatement getPreparedStatement()

Description copied from interface: SQLListenerContext

getPreparedStatement in interface SQLListenerContext

Returns:

the underlying prepared statement or the first if its batch query

getData

public Object getData(String dataKey)

Description copied from interface: SQLListenerContext

The context getData is a general purpose place that listeners can place objects. It allows listeners to pass context between themselves during callbacks.

Specified by:

getData in interface SQLListenerContext

Parameters:

dataKey - the key to look up

Returns:

the context object under that key

setData

public void setData(String dataKey,
                    Object value)

Description copied from interface: SQLListenerContext

The context setData is a general purpose place that listeners can place objects. It allows listeners to pass context between themselves during callbacks.

A good time to place objects into the context is during SQLDetailedListener.start(SQLListenerContext) and then access if after that.

Specified by:

setData in interface SQLListenerContext

Parameters:

dataKey - the key to use

value - the value to place under that key

toString

public String toString()

Overrides:

toString in class Object
