public void setExecutorServiceProvider(java.util.function.Supplier<? extends CloseableExecutorService> provider)

Specified by:

setExecutorServiceProvider in interface ManagedExecutorServiceSupplier

Parameters:

provider - The Supplier of CloseableExecutorService-s to be used when asynchronous execution is required. If null then a single-threaded ad-hoc service is used.

Specified by:

getUnsupportedAttributePolicy in interface SftpUnsupportedAttributePolicyProvider

Returns:

The UnsupportedAttributePolicy to use if failed to access some local file attributes

setUnsupportedAttributePolicy

public void setUnsupportedAttributePolicy(UnsupportedAttributePolicy p)

Parameters:

p - The UnsupportedAttributePolicy to use if failed to access some local file attributes - never null

getFileSystemAccessor

public SftpFileSystemAccessor getFileSystemAccessor()

Specified by:

getFileSystemAccessor in interface SftpFileSystemAccessorProvider

The SftpFileSystemAccessor to use for accessing files and directories

setFileSystemAccessor

public void setFileSystemAccessor(SftpFileSystemAccessor accessor)

Specified by:

setFileSystemAccessor in interface SftpFileSystemAccessorManager

getErrorStatusDataHandler

public SftpErrorStatusDataHandler getErrorStatusDataHandler()
