AbstractPageMapEntry

public AbstractPageMapEntry()

Method Detail

getNumericId

public int getNumericId()

Specified by:

getNumericId in interface IPageMapEntry

Returns:

A stable identifier for this page map entry

See Also:

IPageMapEntry.getNumericId()

getPage

public abstract Page getPage()

Specified by:

getPage in interface IPageMapEntry

Returns:

Gets the page, possibly creating it on the fly.

See Also:

IPageMapEntry.getPage()

getPageClass

public java.lang.Class getPageClass()

Failing to override this method could be pretty expensive because this default implementation calls getPage(), which probably creates the page. That's a lot of work to do in order to simply determine the page's class. So, if there's an easy way to implement this method, that might be desirable.

Specified by:

getPageClass in interface IPageMapEntry

Returns:

The class of page stored in this page map entry (which can be used by an eviction strategy to prioritize evictions)

See Also:

IPageMapEntry.getPageClass()

setNumericId

public void setNumericId(int id)

Specified by:

setNumericId in interface IPageMapEntry

Parameters:

id - The numeric id for this entry

IPageMapEntry.setNumericId(int)
