方法详细资料

accept

public boolean accept(Object o)

指定者:

accept 在类中 AbstractJoSQLFilter

accept

public boolean accept(File f)

Apply the WHERE clause of the statement to the File 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 File objects). You can get access to exception by using: AbstractJoSQLFilter.getException().

指定者:

accept 在接口中 FileFilter

参数:

f - The file to evaluate the WHERE on.

返回:

true if the WHERE clause evaluates to true.

getExpectedClass

public Class getExpectedClass()

Always returns File.

指定者:

getExpectedClass 在类中 AbstractJoSQLFilter

返回:

The file class.
