Constructor Detail

Attribute

public Attribute(String name,
                 boolean nameIsLocalizable,
                 ValueType type,
                 Object defaultValue,
                 boolean permanent,
                 boolean editable,
                 boolean showAsLabel,
                 String ownerTypeName,
                 String modelExtensionId)

Constructor.

Parameters:

name - name of the attribute

nameIsLocalizable - whether the name is localizable

type - value type

defaultValue - default attribute value

permanent - whether the attribute is permanent

editable - whether the attribute can be edited

showAsLabel - whether the attribute should be displayed in label

ownerTypeName - the name of the type (in some domain model) which defines this attribute - it might be null, if the attribute is created, but it doesn't matter since such attributes are not localizable

modelExtensionId - the ID of the model extension in which this attribute is defined. It might be null if the attribute is created by user or it is some predefined attribute. In the first case, the attribute is not localizable, in the second, the localized message is taken from the Core plug-in.

Method Detail

getType

public ValueType getType()

isPermanent

public boolean isPermanent()

isNameLocalizable

public boolean isNameLocalizable()

isEditable

public boolean isEditable()

isShowAsLabel

public boolean isShowAsLabel()

getName

public String getName()

getDefaultValue

public Object getDefaultValue()

getDisplayName

public String getDisplayName()

The human readable name of the attribute. If the attribute is localizable (i.e. is a predefined attribute or is defined in some domain model) the localized representation of the name is returned. Otherwise the raw name is returned.

Returns:

The human readable name of the attribute.

validateValue

public boolean validateValue(Object value)

Checks if given value is valid for this attribute.

Parameters:

value - value to check

Returns:

validation result

equals

public boolean equals(Object obj)

Two Attributes are considered equal if their names are equal.

Overrides:

equals in class Object

See Also:

Overrides:

hashCode in class Object

See Also:

Object.hashCode()
