Class DbxClient

java.lang.Object

com.dropbox.core.DbxClient

public final class DbxClient
extends Object

Use this class to make remote calls to the Dropbox API. You'll need an access token first, normally acquired via DbxWebAuth.

This class has no mutable state, so it's thread safe as long as you pass in a thread safe HttpRequestor implementation.

Constructor Detail

DbxClient

public DbxClient(DbxRequestConfig requestConfig,
         String accessToken)

Parameters:

accessToken - The OAuth 2 access token (that you got from Dropbox) that gives your app the ability to make Dropbox API calls against some particular user's account. The standard way to get one of these is to use DbxWebAuth to send your user through Dropbox's OAuth 2 authorization flow.

DbxClient

public DbxClient(DbxRequestConfig requestConfig,
         String accessToken,
         DbxHost host)

The same as DbxClient(DbxRequestConfig, String) except you can also set the hostnames of the Dropbox API servers. This is used in testing. You don't normally need to call this.

Method Detail

getRequestConfig

public DbxRequestConfig getRequestConfig()

Returns the DbxRequestConfig that was passed in to the constructor.

getAccessToken

public String getAccessToken()

Returns the DbxAccessToken that was passed in to the constructor.

getMetadata

public DbxEntry getMetadata(String path)
                     throws DbxException

Get the file or folder metadata for a given path.

 DbxClient dbxClient = ...
 DbxEntry entry = dbxClient.getMetadata("/Photos");
 if (entry == null) {
     System.out.println("No file or folder at that path.");
 } else {
     System.out.print(entry.toStringMultiline());
 }
 

Parameters:

path - The path to the file or folder (see DbxPath).

Returns:

If there is a file or folder at the given path, return the metadata for that path. If there is no file or folder there, return null.

Throws:

DbxException

getMetadataWithChildren

public DbxEntry.WithChildren getMetadataWithChildren(String path)
                                              throws DbxException

Get the metadata for a given path; if the path refers to a folder, get all the children's metadata as well.

 DbxClient dbxClient = ...
 DbxEntry entry = dbxClient.getMetadata("/Photos");
 if (entry == null) {
     System.out.println("No file or folder at that path.");
 } else {
     System.out.print(entry.toStringMultiline());
 }
 

Parameters:

path - The path (starting with "/") to the file or folder (see DbxPath).

Returns:

If there is no file or folder at the given path, return null. Otherwise, return the metadata for that path and the metadata for all its immediate children (if it's a folder).

Throws:

DbxException

getMetadataWithChildrenC

public <C> DbxEntry.WithChildrenC<C> getMetadataWithChildrenC(String path,
                                                     Collector<DbxEntry,? extends C> collector)
                                                   throws DbxException

Same as getMetadataWithChildren(java.lang.String) except instead of always returning a list of DbxEntry objects, you specify a Collector that processes the DbxEntry objects one by one and aggregates them however you want.

This allows your to process the DbxEntry values as they arrive, instead of having to wait for the entire API call to finish before processing the first one. Be careful, though, because the API call may fail in the middle (after you've already processed some entries). Make sure your code can handle that situation. For example, if you're inserting stuff into a database as they arrive, you might want do everything in a transaction and commit only if the entire call succeeds.

Throws:

DbxException

getMetadataWithChildrenIfChanged

public Maybe<DbxEntry.WithChildren> getMetadataWithChildrenIfChanged(String path,
                                                            String previousFolderHash)
                                                              throws DbxException

Get the metadata for a given path and its children if anything has changed since the last time you got them (as determined by the value of DbxEntry.WithChildren.hash from the last result).

Parameters:

path - The path (starting with "/") to the file or folder (see DbxPath).

previousFolderHash - The value of DbxEntry.WithChildren.hash from the last time you got the metadata for this folder (and children).

Returns:

Never returns null. If the folder at the given path hasn't changed since you last retrieved it (i.e. its contents match previousFolderHash), return Maybe.Nothing. If it doesn't match previousFolderHash return either Maybe.Just(null) if there's nothing there or Maybe.Just with the metadata.

Throws:

DbxException

getMetadataWithChildrenIfChangedC

public <C> Maybe<DbxEntry.WithChildrenC<C>> getMetadataWithChildrenIfChangedC(String path,
                                                                     String previousFolderHash,
                                                                     Collector<DbxEntry,? extends C> collector)
                                                                   throws DbxException

Same as getMetadataWithChildrenIfChanged(java.lang.String, java.lang.String) except instead of always returning a list of DbxEntry objects, you specify a Collector that processes the DbxEntry objects one by one and aggregates them however you want.

This allows your to process the DbxEntry values as they arrive, instead of having to wait for the entire API call to finish before processing the first one.

For example, if you're inserting stuff into a database as they arrive, you might want do everything in a transaction and commit only if the entire call succeeds.

Throws:

DbxException

Append a chunk of data to a chunked upload session.

Parameters:

uploadId - The identifier returned by chunkedUploadFirst(byte[]) to identify the chunked upload session.

uploadOffset - The current number of bytes uploaded to the chunked upload session. The server checks this value to make sure it is correct. If it is correct, the contents of data is appended and -1 is returned. If it is incorrect, the correct offset is returned.

chunkSize - The size of the chunk.

writer - A callback that will be called when it's time to actually write out the body of the chunk.

Returns:

If everything goes correctly, returns -1. If the given offset didn't match the actual number of bytes in the chunked upload session, returns the correct number of bytes.

getDelta

public DbxDelta<DbxEntry> getDelta(String cursor)
                            throws DbxException

Return "delta" entries for the contents of a user's Dropbox. This lets you efficiently keep up with the latest state of the files and folders. See DbxDelta for more documentation on what each entry means.

To start, pass in null for cursor. For subsequent calls To get the next set of delta entries, pass in the cursor returned by the previous call.

To catch up to the current state, keep calling this method until the returned object's hasMore field is false.

If your app is a "Full Dropbox" app, this will return all entries for the user's entire Dropbox folder. If your app is an "App Folder" app, this will only return entries for the App Folder's contents.

Throws:

DbxException

getDeltaC

                       throws DbxException

A more generic version of getDelta(java.lang.String). You provide a collector, which lets you process the delta entries as they arrive over the network.

Throws:

DbxException

getDeltaWithPathPrefix

public DbxDelta<DbxEntry> getDeltaWithPathPrefix(String cursor,
                                        String pathPrefix)
                                          throws DbxException

Same as getDelta(java.lang.String), except results are limited to files and folders whose paths are equal to or under the specified pathPrefix.

The pathPrefix is fixed for a given cursor. Whatever pathPrefix you use on the first call to getDelta() must also be passed in on subsequent calls that use the returned cursor.

Parameters:

pathPrefix - A path on Dropbox to limit results to.

Throws:

DbxException

getDeltaCWithPathPrefix

public <C> DbxDeltaC<C> getDeltaCWithPathPrefix(Collector<DbxDeltaC.Entry<DbxEntry>,C> collector,
