Interface AttachmentManager

All Superinterfaces:

JiveManager

public interface AttachmentManager
extends JiveManager

Manages attachment settings. There are three main properties that can administered with respect to attachments:

• Size -- the maximum size in bytes of an individual attachment. Control this value in order to prevent users from uploading massive files that choke the server.
• Attachments Per Object -- control the number of attachments that people are allowed to add to each object.
• Allowed Types -- the file types that are allowed or disallowed to be attachments.

Method Detail

isAttachmentsEnabled

boolean isAttachmentsEnabled()

Returns true if attachments are enabled, false otherwise.

Returns:

true if attachments are enabled, false otherwise.

setAttachmentsEnabled

void setAttachmentsEnabled(boolean enabled)
                           throws UnauthorizedException

Sets whether attachments are enabled, false otherwise.

Parameters:

enabled - true if attachments are enabled, false otherwise.

Throws:

UnauthorizedException - if not a system administrator.

getMaxAttachmentSize

int getMaxAttachmentSize()

Returns the maximum size of an individual attachment in kilobytes. Trying to create an attachment larger than the max size will fail with an exception. The default maximum attachment size is 1 megabyte, or 1,024 K.

Returns:

the max size in kilobytes of any single attachment.

setMaxAttachmentSize

void setMaxAttachmentSize(int maxAttachmentSize)
                          throws UnauthorizedException

Sets the maximum size of an individual attachment in kilobytes. Trying to create an attachment larger than the max size will fail with an exception. The default maximum attachment size is 1 megabyte, or 1024 K.

Parameters:

maxAttachmentSize - the max size in kilobytes of any single attachment.

Throws:

UnauthorizedException - if not an administrator.

getMaxAttachmentsPerDocument

int getMaxAttachmentsPerDocument()

Returns the maximum number of attachments per document. The default is 5 attachments.

Returns:

the max number of attachments allowed per document.

setMaxAttachmentsPerDocument

void setMaxAttachmentsPerDocument(int maxAttachmentsPerDocument)
                                  throws UnauthorizedException

Sets the maximum number of attachments per document. The default is 5 attachments.

Parameters:

maxAttachmentsPerDocument - the max number of attachments allowed per document.

Throws:

UnauthorizedException - if not an administrator.

isValidType

boolean isValidType(java.lang.String contentType)

Returns true if the content type is valid based on the current settings of the allowAllByDefault flag and the allowed and disallowed types list.

Parameters:

contentType - the content type to test.

Returns:

true if the content type is valid.

addAllowedType

void addAllowedType(java.lang.String contentType)
                    throws UnauthorizedException

Adds a content type to the list of explicitly allowed types.

Parameters:

contentType - a content type to add to the explicitly allowed types list.

Throws:

UnauthorizedException - if not an administrator.

removeAllowedType

void removeAllowedType(java.lang.String contentType)
                       throws UnauthorizedException

Removes a content type fromt he list of explicitly allowed types. If the given content type does not exist in the list, this method does nothing.

Parameters:

contentType - a content type to remove from the explicitly allowed types list.

Throws:

UnauthorizedException - if not an administrator.

getAllowedTypes

java.util.List<java.lang.String> getAllowedTypes()

Returns a List of explicitly allowed types.

Returns:

a List of all explicitly allowed types.

getAllowedTypesAsFileExtensions

java.util.List<java.lang.String> getAllowedTypesAsFileExtensions()

Returns a list of explicitly allowed file types by extensions. For example, image/png would return .png. Since not all allowed mime types may have a ful list of extensions (e.g. application/octet-stream) it's possible that an extension will not be present in the returned list that otherwise will be a valid extension.

addDisallowedType

void addDisallowedType(java.lang.String contentType)
                       throws UnauthorizedException

                          throws UnauthorizedException

Removes a content type from the list of explicitly disallowed types.

Parameters:

contentType - a content type to remove from the explicitly disallowed types list.

Throws:

UnauthorizedException - if not an administrator.

getDisallowedTypes

java.util.List<java.lang.String> getDisallowedTypes()

Returns a List of explicitly disallowed types.

Returns:

a list of all explicitly disallowed types.

getDisallowedTypesAsFileExtensions
