Method Detail

### getName

    String getName()

  Gets the name of this Type.

  Returns:
    the name of this Type

### setName

    void setName(String aName)

    the description of this Type

### setDescription

    void setDescription(String aDescription)

  Sets the verbose description of this Type.

  Parameters:
    `aDescription` - the description of this Type

### getSupertypeName

    String getSupertypeName()

  Gets the name of the supertype for this Type. This is the Type from which this Type inherits.

  Returns:
    the name of the supertype for this Type

### setSupertypeName

    void setSupertypeName(String aTypeName)

  Sets the name of the supertype for this Type. This is the Type from which this Type inherits.

  Parameters:
    `aTypeName` - the name of the supertype for this Type

### getFeatures

    FeatureDescription[] getFeatures()

  Gets the descriptions of the features for this Type.

  Returns:
    the descriptions of the features for this Type.

### setFeatures

    void setFeatures(FeatureDescription[] aFeatures)

  Sets the descriptions of the features for this Type.

  Parameters:
    `aFeatures` - descriptions of the features for this Type.

### getAllowedValues

    AllowedValue[] getAllowedValues()

  Gets the allowed values for instances of this Type. This is used only for special "enumerated types" that extend the String type and define a specific set of allowed values. For all other Types this will return `null`. Note that if a type has allowed values, it may not have features.

  Returns:
    the allowed values for instances of this Type

### setAllowedValues

    void setAllowedValues(AllowedValue[] aAllowedValues)

  Sets the allowed values for instances of this Type. This is used only for special "enumerated types" that extend the String type and define a specific set of allowed values. For all other Types this property should be `null`. Note that if a type has allowed values, it may not have features.

  Parameters:
    `aAllowedValues` - the allowed values for instances of this Type

### addFeature

    FeatureDescription addFeature(String aFeatureName,
                                  String aDescription,
                                  String aRangeTypeName)

  Convenience method which adds a FeatureDescription to this TypeDescription.

  Parameters:
    `aFeatureName` - name of feature to add
    `aDescription` - verbose description of the feature
    `aRangeTypeName` - name of feature's range type
  Returns:
    description of the new Feature

### addFeature

    FeatureDescription addFeature(String aFeatureName,
                                  String aDescription,
                                  String aRangeTypeName,
                                  String aElementTypeName,
                                  Boolean aMultipleReferencesAllowed)

  Convenience method which adds a FeatureDescription to this TypeDescription. Used for array or list valued features, which have additional attributes.

  Parameters:
    `aFeatureName` - name of feature to add
    `aDescription` - verbose description of the feature
    `aRangeTypeName` - name of feature's range type
    `aElementTypeName` - type of element expected to be contained in the array or list
    `aMultipleReferencesAllowed` - whether an array or list that's assigned to this feature can also be referenced from another feature. This is a Boolean object so that the null value can be used to represent the case where the user has not specified a value.
  Returns:
    description of the new Feature
