Method Detail

getName

public java.lang.String getName()

Get the name of the type.

Specified by:

getName in interface Type

Returns:

The name of the type.

getSuperType

public Type getSuperType()

Get the super type.

Returns:

The super type or null for Top.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getAppropriateFeatures

@Deprecated
public java.util.Vector<Feature> getAppropriateFeatures()

Deprecated.

Get a vector of the features for which this type is the domain. Features will be returned in no particular order.

Specified by:

getAppropriateFeatures in interface Type

Returns:

The vector.

getNumberOfFeatures

public int getNumberOfFeatures()

Get the number of features for which this type defines the range.

Specified by:

getNumberOfFeatures in interface Type

Returns:

The number of features.

isAnnotationType

public boolean isAnnotationType()

Check if this is an annotation type.

Returns:

true, if this is an annotation type; false, else.

getTypeSystem

public TypeSystem getTypeSystem()

Get the type hierarchy that this type belongs to.

Returns:

The type hierarchy.

getCode

public int getCode()

Return the internal integer code for this type. This is only useful if you want to work with the low-level API.

Returns:

The internal code for this type, >=0.

compareTo

public int compareTo(TypeImpl t)

Note: you can only compare types from the same type system. If you compare types from different type systems, the result is undefined.

Specified by:

compareTo in interface java.lang.Comparable<TypeImpl>

getFeatureByBaseName

public Feature getFeatureByBaseName(java.lang.String featureName)

Description copied from interface: Type

Retrieve a feature for this type. Inherited features can also be retrieved this way.

Specified by:

getFeatureByBaseName in interface Type

Parameters:

featureName - The short, unqualified name of the feature.

Returns:

The feature, if it exists; null, else.

org.apache.uima.cas.Type#getFeature(java.lang.String)

getShortName

public java.lang.String getShortName()

Description copied from interface: Type

Get the unqualified, short name of this type.

Specified by:

getShortName in interface Type

Returns:

The short name of this type.

See Also:

Type.getShortName()

isPrimitive

public boolean isPrimitive()

Description copied from interface: Type

Check if the type is one of the primitive types.

Specified by:

isPrimitive in interface Type

Returns:

true iff type is a primitive type.

See Also:

Type.isPrimitive()

isFeatureFinal

public boolean isFeatureFinal()

Description copied from interface: Type

Check if type is feature final, i.e., if no more new features may be defined for it.

Specified by:

isFeatureFinal in interface Type

Returns:

If type is feature final.

See Also:

Type.isFeatureFinal()

isInheritanceFinal

public boolean isInheritanceFinal()

Description copied from interface: Type

Check if type is inheritance final, i.e., if new types can be derived from it.

Specified by:

isInheritanceFinal in interface Type

Returns:

If type is inheritance final.

See Also:

Type.isInheritanceFinal()

getFeature

@Deprecated
public Feature getFeature(java.lang.String featureName)

Deprecated.

getFeatures

public java.util.List<Feature> getFeatures()

Description copied from interface: Type

Get a vector of the features for which this type is a subtype of the features' domain (i.e., inherited features are also returned). If you need to know which type introduces a feature, use Feature.getDomain. Features will be listed in no particular order.

Specified by:

getFeatures in interface Type

Returns:

The List of features defined for this type.

isArray

public boolean isArray()

Description copied from interface: Type

Check if the type is an array type.

Specified by:

isArray in interface Type

Returns:

true iff the type is an array type.

getComponentType

Description copied from interface: Type

For array types, returns the component type of the array type. For all other types, it will return null.

Specified by:

getComponentType in interface Type

Returns:

The component type of an array type.
