JCas (Apache UIMA Java SDK 2.10.0 User-Level API Documentation)

All Superinterfaces:

AbstractCas
```
public interface JCas
extends AbstractCas
```
Java Cover Classes based Object-oriented CAS (Common Analysis System) API.
A JCas object provides the starting point for working with the CAS using Java Cover Classes for each type, generated by the utility JCasGen.
This interface extends the CAS Interface, providing all the same functionality, plus some specific to the JCas.
It supports the creation of new instances of CAS types, using the normal Java "new" operator.
You can create a JCas object from a CAS object by calling the getJCas() method on the CAS object.

    Parameters:
    sofaID - -

  - createView
```
JCas createView(String sofaID)
                throws CASException
```
    Create a view and its underlying Sofa (subject of analysis). The view provides access to the Sofa data and the index repository that contains metadata (annotations and other feature structures) pertaining to that Sofa.
    This method creates the underlying Sofa feature structure, but does not set the Sofa data. Setting ths Sofa data must be done by calling setSofaDataArray(FeatureStructure, String), setSofaDataString(String, String) or setSofaDataURI(String, String) on the JCas view returned by this method.
    
    Parameters:
    sofaID - the local view name, before any sofa name mapping is done, for this view (note: this is the same as the associated Sofa name).
    
    Returns:
    The view corresponding to this local name.
    
    Throws:
    
    CASException - - if a View with this name already exists in this CAS
  - getJCas
```
JCas getJCas(Sofa sofa)

    sofa - a Sofa feature structure in this CAS.
    
    Returns:
    The JCas view for the given Sofa.
    
    Throws:
    
    CASException - -
  - getJFSIndexRepository
```
JFSIndexRepository getJFSIndexRepository()
```
    Gets the JCas-based interface to the Index Repository. Provides the same functionality as getFSIndexRepository() except that the methods that take a "type" argument take type arguments obtainable easily from the JCas type.
    
    Returns:
    the JCas-based interface to the index repository
  - getDocumentAnnotationFs
```
TOP getDocumentAnnotationFs()
```
    Gets the document annotation. The object returned from this method can be typecast to org.apache.uima.jcas.tcas.DocumentAnnotation
    The reason that the return type of this method is not DocumentAnnotation is because of problems that arise when using the UIMA Extension ClassLoader to load annotator classes. The DocumentAnnotation type may be defined in the UIMA extension ClassLoader, differently than in the framework ClassLoader.
    
    Returns:
    The one instance of the DocumentAnnotation annotation.
    See Also:
    CAS.getDocumentAnnotation()
  - getStringArray0L
```
StringArray getStringArray0L()
```
    A constant for each cas which holds a 0-length instance. Since this can be a common value, we avoid creating multiple copies of it. All uses can use the same valuee because it is not updatable (it has no subfields). This is initialized lazily on first reference, and reset when the CAS is reset.
    
    Returns:
    0-length instance of a StringArray
  - getIntegerArray0L
```
IntegerArray getIntegerArray0L()
```
    A constant for each cas which holds a 0-length instance. Since this can be a common value, we avoid creating multiple copies of it. All uses can use the same valuee because it is not updatable (it has no subfields). This is initialized lazily on first reference, and reset when the CAS is reset.
    
    Returns:
    0-length instance of an IntegerArray
  - getFSArray0L
```
FSArray getFSArray0L()
```
    A constant for each cas which holds a 0-length instance. Since this can be a common value, we avoid creating multiple copies of it. All uses can use the same valuee because it is not updatable (it has no subfields). This is initialized lazily on first reference, and reset when the CAS is reset.
    
    Returns:
    0-length instance of a FloatArray public abstract FloatArray getFloatArray0L(); /** A constant for each cas which holds a 0-length instance. Since this can be a common value, we avoid creating multiple copies of it. All uses can use the same valuee because it is not updatable (it has no subfields).

                                                         throws CASRuntimeException
```
    Get the standard annotation index restricted to a specific annotation type.
    
    Type Parameters:
    T - the Java class clazz
    Parameters:
    clazz - The JCas cover class for the annotation type the index is restricted to,

  - getAllIndexedFS
```
<T extends TOP> FSIterator<T> getAllIndexedFS(Class<T> clazz)
```
    Gets an iterator over all indexed FeatureStructures of the specified Type (and any of its subtypes). The elements are returned in arbitrary order, and duplicates (if they exist) are not removed.
    
    Type Parameters:
    T - the Java clazz
    Parameters:
    clazz - - the JCas Java class specifing which type and subtypes are included
    
    Returns:
    An iterator that returns all indexed FeatureStructures of the JCas clazz and its subtypes, in no particular order.
  - getViewIterator
```
Iterator<JCas> getViewIterator()
                               throws CASException
```
    Get iterator over all views in this JCas. Each view provides access to Sofa data and the index repository that contains metadata (annotations and other feature structures) pertaining to that Sofa.
    
    Returns:
    an iterator which returns all views. Each object returned by the iterator is of type JCas.
    
    Throws:
    
    CASException - -
  - getViewIterator
```
Iterator<JCas> getViewIterator(String localViewNamePrefix)
                               throws CASException
```
    Get iterator over all views with the given name prefix. Each view provides access to Sofa data and the index repository that contains metadata (annotations and other feature structures) pertaining to that Sofa.
    When passed the prefix namePrefix, the iterator will return all views who name is either exactly equal to namePrefix or is of the form namePrefix.suffix, where suffix can be any String.
    
    Parameters:
    localViewNamePrefix - the local name prefix, before any sofa name mapping is done, for this view (note: this is the same as the associated Sofa name prefix).
    
    Returns:
    an iterator which returns all views with the given name prefix. Each object returned by the iterator is of type JCas.
    
    Throws:
    
    CASException - -
  - protectIndexes
```
AutoCloseable protectIndexes()
```
    Call this method to set up a region, ended by a close() call on the returned object, You can use this or the protectIndexes(Runnable) method to protected the indexes.
    This approach allows arbitrary code between the protectIndexes and the associated close method.
    The close method is best done in a finally block, or using the try-with-resources statement in Java 8.
    
    Returns:
    an object used to record things that need adding back
  - protectIndexes
```
void protectIndexes(Runnable runnable)
```
    Runs the code in the runnable inside a protection block, where any modifications to features done while in this block will be done in a way to protect any indexes which otherwise might become corrupted by the update action; the protection is achieved by temporarily removing the FS (if it is in the indexes), before the update happens. At the end of the block, affected indexes have any removed-under-the-covers FSs added back.
    
    Parameters:
    runnable - code to execute while protecting the indexes.
  - getIndex
```
<T extends TOP> FSIndex<T> getIndex(String label,
                                  Class<T> clazz)
```
    Retrieve an index according to a label and a type specified using a JCas class. The type is used to narrow down the index of a more general type to a more specific one. Generics: T is the associated Java cover class for the type.
    
    Type Parameters:
    T - the Java clazz
    Parameters:
    label - The name of the index.
    clazz - The JCas class (mostly likely written as MyJCasClass.class), which must correspond to a subtype of the type of the index.
    
    Returns:
    The specified, or null if an index with that name doesn't exist.
    
    Throws:
    
    CASRuntimeException - When clazz doesn't correspond to a subtype of the index's type.
