Method Detail

getFieldOrder

protected java.util.List<java.lang.String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names

getMajor

public int getMajor()

Returns:

The major version number of the operating system.

getMinor

public int getMinor()

Returns:

The minor version number of the operating system.

getBuildNumber

public int getBuildNumber()

Returns:

The build number of the operating system.

getPlatformId

public int getPlatformId()

Returns:

The operating system platform. This member can be VER_PLATFORM_WIN32_NT.

getServicePack

public java.lang.String getServicePack()

Returns:

String, such as "Service Pack 3", that indicates the latest Service Pack installed on the system.
If no Service Pack has been installed, the string is empty.

getSuiteMask

public int getSuiteMask()

Returns:

A bit mask that identifies the product suites available on the system.

getProductType

public byte getProductType()

Returns:

Any additional information about the system.
