public RemoteFileStreamingInboundChannelAdapterSpec()

Method Details

remoteFileSeparator

public S remoteFileSeparator(String remoteFileSeparator)

Configure the file name path separator used by the remote system. Defaults to '/'.

Parameters:

remoteFileSeparator - the remoteFileSeparator.

Returns:

the spec.

remoteDirectory

public S remoteDirectory(String remoteDirectory)

Specify the full path to the remote directory.

Parameters:

remoteDirectory - the remoteDirectory.

Returns:

the spec.

remoteDirectory

public S remoteDirectory(Expression remoteDirectoryExpression)

Specify an expression that evaluates to the full path to the remote directory.

Parameters:

remoteDirectoryExpression - The remote directory expression.

Returns:

the spec.

remoteDirectory

public S remoteDirectory(Function<Message<?>,String> remoteDirectoryFunction)

Specify a function that is invoked to determine the full path to the remote directory.

Parameters:

remoteDirectoryFunction - The remote directory function.

Returns:

the spec.

filter

public S filter(FileListFilter<F> filter)

Configure a FileListFilter to be applied to the remote files before copying them.

Parameters:

filter - the filter.

Returns:

the spec.

filterExpression

public S filterExpression(String expression)

Configure the ExpressionFileListFilter.

Parameters:

expression - the SpEL expression for files filtering.

Returns:

the spec.

• ExpressionFileListFilter

maxFetchSize

public S maxFetchSize(int maxFetchSize)

Specify the maximum number of remote files that will be fetched on each fetch attempt. A small number is recommended when multiple application instances are running, to avoid one instance from "grabbing" all the files.
