Method Detail

getAllContainedWritingResourceProviders

@Nonnull
@Nonempty
@ReturnsMutableCopy
public ICommonsList<IWritableResourceProvider> getAllContainedWritingResourceProviders()

supportsWriting

public final boolean supportsWriting(@Nullable
                                     String sName)

Description copied from interface: IWritableResourceProvider

Check if this resource provider can handle the resource with the passed name. If there is no real check on whether your resource provider can handle it, simply return true.

Specified by:

supportsWriting in interface IWritableResourceProvider

Parameters:

sName - The name to check. May be null.

Returns:

true if the name is not null and can be handled by this provider, false otherwise.

getWritableResource

@Nonnull
@OverrideOnDemand
public IWritableResource getWritableResource(@Nonnull
                                             String sName)

Description copied from interface: IWritableResourceProvider

Get the resource specified by the given name for writing.

Specified by:

getWritableResource in interface IWritableResourceProvider

Parameters:

sName - The name of the resource to resolve.

Returns:

The writable resource. Never null.

getWritableResourceIf

@Nullable
public IWritableResource getWritableResourceIf(@Nonnull
                                               String sName,
                                               @Nonnull
                                               Predicate<? super IWritableResource> aReturnFilter)

getOutputStream

@Nullable
public OutputStream getOutputStream(@Nonnull
                                    String sName,
                                    @Nonnull
                                    EAppend eAppend)

Description copied from interface: IWritableResourceProvider

Get the OutputStream specified by the given name for reading. This method may be called without prior call to IWritableResourceProvider.supportsWriting(String).

Specified by:

getOutputStream in interface IWritableResourceProvider

Parameters:

sName - The name of the resource to resolve.

eAppend - Appending mode. May not be null.

Returns:

The OutputStream. May be null if the underlying resource does not exist and cannot be created or if IWritableResourceProvider.supportsWriting(String) returns false.
