Class PropertyFlags

java.lang.Object
  com.sap.netweaver.bc.rf.common.property.PropertyFlags

public final class PropertyFlags

extends Object

Class implementing the internal system attributes of a property. They are mapped into a bit array hold by the flags field in the property class for greater performance and less memory consumption.

Field Summary

static int	HIDDEN_BIT_MASK Bit mask for the internal system attribute named "hidden".
static int	LIVE_BIT_MASK Bit mask for the internal system attribute named "live".
static int	READONLY_BIT_MASK Bit mask for the internal system attribute named "read only".
static int	REQUIRED_BIT_MASK Bit mask for the internal system attribute named "required".

Constructor Summary

PropertyFlags()

Method Summary

static int	constructFlags(boolean required, boolean live, boolean readOnly, boolean hidden) Construct property flags based on given explicit internal system attributes.
static boolean	isHidden(int flags) Returns true if these property flags indicate that its holding property has the internal system attribute "hidden".
static boolean	isLive(int flags) Returns true if these property flags indicate that its holding property has the internal system attribute "live".
static boolean	isReadOnly(int flags) Returns true if these property flags indicate that its holding property has the internal system attribute "read only".
static boolean	isRequired(int flags) Returns true if these property flags indicate that its holding property has the internal system attribute "required".

Method Detail

constructFlags

public static final int constructFlags(boolean required,
                                       boolean live,
                                       boolean readOnly,
                                       boolean hidden)

Construct property flags based on given explicit internal system attributes.

Parameters:

required - true if this property should be required

live - true if this property should be live

readOnly - true if this property should be read only

hidden - true if this property should be hidden

Returns:

property flags

isRequired

public static final boolean isRequired(int flags)

Returns true if these property flags indicate that its holding property has the internal system attribute "required".

Parameters:

flags - bit array holding internal system attributes according to PropertyFlags bit mask fields

Returns:

true if this property is required

isLive

public static final boolean isLive(int flags)

Returns true if these property flags indicate that its holding property has the internal system attribute "live".

Parameters:

flags - bit array holding internal system attributes according to PropertyFlags bit mask fields

Returns:

true if this property is live

isReadOnly

public static final boolean isReadOnly(int flags)

Returns true if these property flags indicate that its holding property has the internal system attribute "read only".

Parameters:

flags - bit array holding internal system attributes according to PropertyFlags bit mask fields

Returns:

true if this property is read only

isHidden

public static final boolean isHidden(int flags)

Returns true if these property flags indicate that its holding property has the internal system attribute "hidden".

Parameters:

flags - bit array holding internal system attributes according to PropertyFlags bit mask fields

Returns:

true if this property is hidden
