方法详细资料

accept

public boolean accept(Object o)

从类复制的说明: DefaultObjectFilter

Apply the WHERE clause of the statement to the object passed in. If an exception is thrown by the execution of the WHERE clause the Query is marked as "dirty" and the where clause is no longer executed on the passed in objects (since it is likely that the WHERE clause will fail for all objects). You can get access to exception by using: AbstractJoSQLFilter.getException().

覆盖:

accept 在类中 DefaultObjectFilter

参数:

o - The object to evaluate the WHERE on.

返回:

true if the WHERE clause evaluates to true.

isLoggable

public boolean isLoggable(LogRecord l)

Apply the WHERE clause of the statement to the LogRecord passed in. If an exception is thrown by the execution of the WHERE clause the Query is marked as "dirty" and the where clause is no longer executed on the passed in files (since it is likely that the WHERE clause will fail for all LogRecord objects). You can get access to exception by using: AbstractJoSQLFilter.getException().

参数:

l - The log record to evaluate the WHERE on.

返回:

true if the WHERE clause evaluates to true.

getExpectedClass

public Class getExpectedClass()

Always returns LogRecord.

覆盖:

getExpectedClass 在类中 DefaultObjectFilter

返回:

The log record class.
