## Uses of Interface
net.sf.jasperreports.engine.JRVirtualizable

Packages that use JRVirtualizable
net.sf.jasperreports.engine | Provides access to the library's main functionality through façade classes for compiling, filling and exporting reports and also publishes the library's main interfaces and classes.
net.sf.jasperreports.engine.base | Contains base implementations for the library's main interfaces.
net.sf.jasperreports.engine.fill | Contains fill time implementations for the library's main interfaces and the entire engine used in the filling process (the actual core of JasperReports).

Uses of JRVirtualizable in net.sf.jasperreports.engine

Methods in net.sf.jasperreports.engine with parameters of type JRVirtualizable
`void` | `JRVirtualizer.clearData(JRVirtualizable o)` Called when the virtual object paged-out data should be freed.
`void` | `JRVirtualizer.deregisterObject(JRVirtualizable o)` Lets this virtualizer know that it no longer must track the object.
`void` | `JRVirtualizer.registerObject(JRVirtualizable o)` Lets this virtualizer know that it must track the object.
`void` | `JRVirtualizer.requestData(JRVirtualizable o)` Called when the virtual object must be paged-in.
`void` | `JRVirtualizer.touch(JRVirtualizable o)` Lets the virtualizer know that this object is still being used.
`void` | `JRVirtualizer.virtualizeData(JRVirtualizable o)` Called when the virtual object should be paged-out.
