Method Detail

closeImp

protected void closeImp()
                 throws java.lang.Exception

Description copied from class: AbstractIterableInput

Subclass implementation of guts of close() method.

Subclasses must implement this to do the actual work required by close(). Feel free to throw exceptions; these are caught inside the close() itself and applied to the exception variable. Thus, you can focus on the actual task instead of paperwork.

Specified by:

closeImp in class AbstractIterableInput<Naming<java.lang.Object>>

Throws:

java.lang.Exception

fetchImp

protected boolean fetchImp()
                    throws java.lang.Exception

Description copied from class: AbstractIterableInput

Subclass implementation of guts of fetch() method.

Subclasses must implement this to do the actual work required by fetch(). Feel free to throw exceptions; these are caught inside the fetch() itself and applied to the exception variable. Thus, you can focus on the actual task instead of paperwork.

Specified by:

fetchImp in class AbstractIterableInput<Naming<java.lang.Object>>

Returns:

true if fetch successful

Throws:

java.lang.Exception

openImp

protected void openImp()
                throws java.lang.Exception

Description copied from class: AbstractIterableInput

Subclass implementation of guts of open() method.

Subclasses must implement this to do the actual work required by open(). Feel free to throw exceptions; these are caught inside the open() itself and applied to the exception variable. Thus, you can focus on the actual task instead of paperwork.

Specified by:

openImp in class AbstractIterableInput<Naming<java.lang.Object>>

Throws:

java.lang.Exception

copy

public DataRecordSource copy()

Description copied from class: DataRecordSource

Makes a copy of this DataRecordSource, that you can iterate over separately.

Specified by:

Returns:

copy of this source
