Field Detail

field1

public Winevt.EVT_VARIANT.field1_union field1

Exposed to follow JNA rules, use the getValue() method to manipulate values!

Count

public int Count

The number of elements in the array of values. Use Count if the Type member has the EVT_VARIANT_TYPE_ARRAY flag set.

Exposed to follow JNA rules, use getValue() and setValue(com.sun.jna.platform.win32.Winevt.EVT_VARIANT_TYPE, java.lang.Object) methods to manipulate values!

Type

public int Type

A flag that specifies the data type of the variant. For possible values, see the Winevt.EVT_VARIANT_TYPE enumeration. The variant contains an array of values, if the EVT_VARIANT_TYPE_ARRAY flag is set. The members that end in "Arr" contain arrays of values. For example, you would use the StringArr member to access the variant data if the type is EvtVarTypeString and the EVT_VARIANT_TYPE_ARRAY flag is set. You can use the Winevt.EVT_VARIANT_TYPE_MASK constant to mask out the array bit to determine the variant's type.

Exposed to follow JNA rules, use getValue() and setValue(com.sun.jna.platform.win32.Winevt.EVT_VARIANT_TYPE, java.lang.Object) methods to manipulate values!

Method Detail

getFieldOrder

protected List<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

use

public void use(Pointer m)

isArray

public boolean isArray()

getVariantType

public Winevt.EVT_VARIANT_TYPE getVariantType()

setValue

public void setValue(Winevt.EVT_VARIANT_TYPE type,
                     Object value)

Parameters:

type -

value -

getValue

public Object getValue()

Returns:

value contained in the EVT_VARIANT
