```
    Creates a request to resolve the specified metadata from the local repository.
    
    Parameters:
    metadata - The metadata to resolve, may be null.
  - MetadataRequest
```
public MetadataRequest(Metadata metadata,
               RemoteRepository repository,
               String context)
```
    Creates a request with the specified properties.
    
    Parameters:
    metadata - The metadata to resolve, may be null.

- Method Detail
  - getMetadata
```
public Metadata getMetadata()
```
    Gets the metadata to resolve.
    
    Returns:
    The metadata or null if not set.
  - setMetadata
```
public MetadataRequest setMetadata(Metadata metadata)
```
    Sets the metadata to resolve.
    
    Parameters:
    metadata - The metadata, may be null.
    
    Returns:
    This request for chaining, never null.
  - getRepository
```
public RemoteRepository getRepository()
```
    Gets the repository from which the metadata should be resolved.
    
    Returns:
    The repository or null to resolve from the local repository.
  - setRepository
```
public MetadataRequest setRepository(RemoteRepository repository)
```
    Sets the repository from which the metadata should be resolved.
    
    Parameters:
    repository - The repository, may be null to resolve from the local repository.
    
    Returns:
    This request for chaining, never null.
  - getRequestContext
```
public String getRequestContext()
```
    Gets the context in which this request is made.
    
    Returns:
    The context, never null.
  - setRequestContext
```
public MetadataRequest setRequestContext(String context)
```
    Sets the context in which this request is made.
    
    Parameters:
    context - The context, may be null.
    
    Returns:
    This request for chaining, never null.
  - isDeleteLocalCopyIfMissing
```
public boolean isDeleteLocalCopyIfMissing()
```
    Indicates whether the locally cached copy of the metadata should be removed if the corresponding file does not exist (any more) in the remote repository.
    
    Returns:
    true if locally cached metadata should be deleted if no corresponding remote file exists, false to keep the local copy.
  - setDeleteLocalCopyIfMissing
```
public MetadataRequest setDeleteLocalCopyIfMissing(boolean deleteLocalCopyIfMissing)
```
    Controls whether the locally cached copy of the metadata should be removed if the corresponding file does not exist (any more) in the remote repository.
    
    Parameters:
    deleteLocalCopyIfMissing - true if locally cached metadata should be deleted if no corresponding remote file exists, false to keep the local copy.
    
    Returns:
    This request for chaining, never null.
  - isFavorLocalRepository
```
public boolean isFavorLocalRepository()
```
    Indicates whether the metadata resolution should be suppressed if the corresponding metadata of the local repository is up-to-date according to the update policy of the remote repository. In this case, the metadata resolution will even be suppressed if no local copy of the remote metadata exists yet.
    
    Returns:
    true to suppress resolution of remote metadata if the corresponding metadata of the local repository is up-to-date, false to resolve the remote metadata normally according to the update policy.
  - setFavorLocalRepository
```
public MetadataRequest setFavorLocalRepository(boolean favorLocalRepository)
```
    Controls resolution of remote metadata when already corresponding metadata of the local repository exists. In cases where the local repository's metadata is sufficient and going to be preferred, resolution of the remote metadata can be suppressed to avoid unnecessary network access.
    
    Parameters:
    favorLocalRepository - true to suppress resolution of remote metadata if the corresponding metadata of the local repository is up-to-date, false to resolve the remote metadata normally according to the update policy.
    
    Returns:
    This request for chaining, never null.
  - getTrace
```
public RequestTrace getTrace()
```
    Gets the trace information that describes the higher level request/operation in which this request is issued.
    
    Returns:
    The trace information about the higher level operation or null if none.
  - setTrace
```
public MetadataRequest setTrace(RequestTrace trace)
```
    Sets the trace information that describes the higher level request/operation in which this request is issued.
    
    Parameters:
    trace - The trace information about the higher level operation, may be null.
    
    Returns:
    This request for chaining, never null.
  - toString
```
public String toString()
```
    Overrides:
