JvmOptionBag (admin-config-api 7.0.0-M2 API)

All Superinterfaces:

org.jvnet.hk2.config.ConfigBeanProxy

All Known Subinterfaces:

JavaConfig, Profiler
```
public interface JvmOptionBag
extends org.jvnet.hk2.config.ConfigBeanProxy
```
Factored out the list of jvm-options from at least two other interfaces that have them: java-config and profiler. Similar to PropertyBag

- Method Detail
  - getJvmOptions
```
List<String> getJvmOptions()
```
  - setJvmOptions
```
void setJvmOptions(List<String> options)
            throws PropertyVetoException
```
    Throws:
    
    PropertyVetoException
  - getXmxMegs
```
@DuckTyped
int getXmxMegs()
```
    It's observed that many a time we need the value of max heap size. This is useful when deciding if a user is misconfiguring the JVM by specifying -Xmx that is smaller than -Xms. Sun's JVM for example, bails out with Incompatible minimum and maximum heap sizes specified when that happens. It's generally better to do some basic validations in those cases and that's when this method may be useful.
    
    Returns:
    
    an integer specifying the actual max heap memory (-Xmx) configured. If it's specified as -Xmx2g, then 2*1024 i.e. 2048 is returned. Returns -1 if no -Xmx is specified.
  - getXmsMegs
```
@DuckTyped
int getXmsMegs()
```
    see #getXmxMegs
    
    Returns:
    
    integer specifying -Xms in megabytes, or -1
  - contains
