 package com.fasterxml.jackson.core;

Shared base class for streaming processing contexts used during reading and writing of Json content using Streaming API. This context is also exposed to applications: context object can be used by applications to get an idea of relative position of the parser/generator within json content being processed. This allows for some contextual processing: for example, output within Array context can differ from that of Object context.
 
 public abstract class JsonStreamContext
 {
     // // // Type constants used internally
 
     protected final static int TYPE_ROOT = 0;
     protected final static int TYPE_ARRAY = 1;
     protected final static int TYPE_OBJECT = 2;
 
     protected int _type;

    
Index of the currently processed entry. Starts with -1 to signal that no entries have been started, and gets advanced each time a new entry is started, either by encountering an expected separator, or with new values if no separators are expected (the case for root context).
 
     protected int _index;

Accessor for finding parent context of this context; will return null for root context.
 
     public abstract JsonStreamContext getParent();

    
Method that returns true if this context is an Array context; that is, content is being read from or written to a Json Array.
 
     public final boolean inArray() { return  == ; }

    
Method that returns true if this context is a Root context; that is, content is being read from or written to without enclosing array or object structure.
 
     public final boolean inRoot() { return  == ; }

    
Method that returns true if this context is an Object context; that is, content is being read from or written to a Json Object.
 
     public final boolean inObject() { return  == ; }

    
Method for accessing simple type description of current context; either ROOT (for root-level values), OBJECT (for field names and values of JSON Objects) or ARRAY (for values of JSON Arrays)
 
     public final String getTypeDesc() {
         switch () {
         case return "ROOT";
         case return "ARRAY";
         case return "OBJECT";
         }
         return "?";
     }

    

Returns:
Number of entries that are complete and started.
    public final int getEntryCount()
    {
        return  + 1;
    }

    

Returns:
Index of the currently processed entry, if any
    public final int getCurrentIndex()
    {
        return ( < 0) ? 0 : ;
    }

    
Method for accessing name associated with the current location. Non-null for FIELD_NAME and value events that directly follow field names; null for root level and array values.
    public abstract String getCurrentName();
