Examples of MemoryUsage

flex2.compiler.util.Benchmark.MemoryUsage
This class handles MXML language specific configuration options. This includes things like compatibility-version, minimum-supported-version, and qualified-type-selectors. This class should not to be confused with flex2.compiler.mxml.MxmlConfiguration, which is where MXML subcompiler configuration options are declared and flex2.compiler.common.CompilerConfiguration, which is where flex2.compiler.mxml.MxmlConfiguration is defined. @author Clement Wong

MXBean Mapping
MemoryUsage is mapped to a {@link CompositeData CompositeData}with attributes as specified in the {@link #from from} method. @author Mandy Chung @version 1.17, 11/17/05 @since 1.5
org.apache.activemq.usage.MemoryUsage
Used to keep track of how much of something is being used so that a productive working set usage can be controlled. Main use case is manage memory usage. @org.apache.xbean.XBean
