RepeatedFieldBuilder (Protocol Buffers [Core] - shaded version 3.5.1 0.9 API)

java.lang.Object
- com.github.os72.protobuf351.RepeatedFieldBuilder<MType,BType,IType>

Type Parameters:
MType - the type of message for the field
BType - the type of builder for the field
IType - the common interface for the message and the builder

All Implemented Interfaces:

AbstractMessage.BuilderParent, GeneratedMessage.BuilderParent
```
public class RepeatedFieldBuilder<MType extends GeneratedMessage,BType extends GeneratedMessage.Builder,IType extends MessageOrBuilder>
extends Object
implements GeneratedMessage.BuilderParent
```
RepeatedFieldBuilder implements a structure that a protocol message uses to hold a repeated field of other protocol messages. It supports the classical use case of adding immutable Message's to the repeated field and is highly optimized around this (no extra memory allocations and sharing of immutable arrays).
It also supports the additional use case of adding a Message.Builder to the repeated field and deferring conversion of that Builder to an immutable Message. In this way, it's possible to maintain a tree of Builder's that acts as a fully read/write data structure.
Logically, one can think of a tree of builders as converting the entire tree to messages when build is called on the root or when any method is called that desires a Message instead of a Builder. In terms of the implementation, the SingleFieldBuilder and RepeatedFieldBuilder classes cache messages that were created so that messages only need to be created when some change occurred in its builder or a builder for one of its descendants.

public RepeatedFieldBuilder(List<MType> messages,
                    boolean isMessagesListMutable,

```
    Constructs a new builder with an empty list of messages.
    
    Parameters:
    messages - the current list of messages
    isMessagesListMutable - Whether the messages list is mutable
    parent - a listener to notify of changes
    isClean - whether the builder is initially marked clean
- Method Detail
  - dispose
```
public void dispose()
```
  - getCount
```
public int getCount()

    Gets the count of items in the list.
    
    Returns:
    the count of items in the list.
  - isEmpty
```
public boolean isEmpty()
```

    Returns:
    whether the list is empty
  - getMessage
```
public MType getMessage(int index)
```
    Get the message at the specified index. If the message is currently stored as a Builder, it is converted to a Message by calling Message.Builder.buildPartial() on it.
    
    Parameters:
    index - the index of the message to get
    
    Returns:
    the message for the specified index
  - getBuilder
```
public BType getBuilder(int index)
```
    Gets a builder for the specified index. If no builder has been created for that index, a builder is created on demand by calling Message.toBuilder().
    
    Parameters:
    index - the index of the message to get
    
    Returns:
    The builder for that index
  - getMessageOrBuilder
```
public IType getMessageOrBuilder(int index)
```
    Gets the base class interface for the specified index. This may either be a builder or a message. It will return whatever is more efficient.
    
    Parameters:
    index - the index of the message to get
    
    Returns:
    the message or builder for the index as the base class interface
  - setMessage
```
public RepeatedFieldBuilder<MType,BType,IType> setMessage(int index,
                                                 MType message)
```
    Sets a message at the specified index replacing the existing item at that index.
    
    Parameters:
    index - the index to set.
    message - the message to set
    
    Returns:
    the builder
  - addMessage
```
public RepeatedFieldBuilder<MType,BType,IType> addMessage(MType message)
```
    Appends the specified element to the end of this list.

```
    Inserts the specified message at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

  - addBuilder
```
public BType addBuilder(int index,
               MType message)

```
    Removes the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.
    
    Parameters:
    index - the index at which to remove the message

```
public void markDirty()
```
    Description copied from interface: AbstractMessage.BuilderParent
    
    A builder becomes dirty whenever a field is modified -- including fields in nested builders -- and becomes clean when build() is called. Thus, when a builder becomes dirty, all its parents become dirty as well, and when it becomes clean, all its children become clean. The dirtiness state is used to invalidate certain cached values.
    To this end, a builder calls markDirty() on its parent whenever it transitions from clean to dirty. The parent must propagate this call to its own parent, unless it was already dirty, in which case the grandparent must necessarily already be dirty as well. The parent can only transition back to "clean" after calling build() on all children.
