public VersionListing()

Method Detail

getVersionSummaries

public List<COSVersionSummary> getVersionSummaries()

Gets the list of version summaries describing the versions stored in the associated COS bucket. Callers should remember that listings for large buckets can be truncated for performance reasons, so callers might need to make additional calls to COS#listVersions(ListVersionsRequest) to get additional results. Callers should always check isTruncated() to determine if a listing is truncated or not.

Returns:

A list of the version summaries describing the versions stored in the associated COS bucket.

setVersionSummaries

public void setVersionSummaries(List<COSVersionSummary> versionSummaries)

For internal use only. Sets the list of version summaries describing the versions stored in the associated COS bucket.

Parameters:

versionSummaries - The version summaries describing the versions stored in the associated COS bucket.

getCommonPrefixes

public List<String> getCommonPrefixes()

Gets the common prefixes included in this version listing. Common prefixes are only present if a delimiter was specified in the original request.

Each common prefix represents a set of keys in the COS bucket that have been condensed and omitted from the version summary results. This allows applications to organize and browse their keys hierarchically, similar to how a file system organizes files into directories.

For example, consider a bucket that contains the keys:

• "foo/bar/baz"
• "foo/bar/bash"
• "foo/bar/bang"
• "foo/boo"

If calling listVersions with a prefix value of "foo/" and a delimiter value of "/" on this bucket, the returned VersionListing will contain one entry in the common prefixes list ("foo/bar/") and none of the keys beginning with that common prefix will be included in the version summaries list.

Returns:

The list of common prefixes included in this version listing. Returns an empty list if no common prefixes are found.

setCommonPrefixes

public void setCommonPrefixes(List<String> commonPrefixes)

For internal use only. Sets the common prefixes for this version listing, representing the key prefixes that were rolled up because of the request's delimiter parameter.

Parameters:

commonPrefixes - The common prefixes for this version listing.

getBucketName

public String getBucketName()

Gets the name of the Qcloud COS bucket containing the versions listed in this VersionListing.

Returns:

The name of the Qcloud COS bucket containing the versions listed in this COSVersionListingVersionListing.

setBucketName

public void setBucketName(String bucketName)

For internal use only. Sets the name of the Qcloud COS bucket containing the versions listed in this COSVersionListing.

Parameters:

bucketName - The name of the Qcloud COS bucket containing the versions listed in this COSVersionListing.

getPrefix

public String getPrefix()

The prefix parameter originally used to request this version listing, or null if no prefix was specified. All object keys included in this version listing start with the specified prefix.

Returns:

The prefix parameter originally used to request this version listing, or null if no prefix was specified.

setPrefix

public void setPrefix(String prefix)

For internal use only. Sets the prefix parameter originally used to request this version listing.

Parameters:

prefix - The prefix parameter originally used to request this version listing.

getKeyMarker

public String getKeyMarker()

The key marker parameter originally used to request this version listing, or null if no key marker was specified. If specified, all object keys included in this version listing will occur lexically (alphabetically) after the specified key marker.

Returns:

The key marker parameter originally used to request this version listing, or null if no key marker was specified.

setKeyMarker

public void setKeyMarker(String keyMarker)

For internal use only. Sets the key marker parameter originally used to request this version listing.

Parameters:

keyMarker - The key marker parameter originally used to request this version listing.

getVersionIdMarker

public String getVersionIdMarker()

Gets the value of the version ID marker parameter used to request this version listing. Returns null if no version ID marker was otherwise specified.

Returns:

The version ID marker parameter originally used to request this version listing. Returns null if no version ID marker otherwise was specified.

setVersionIdMarker

public void setVersionIdMarker(String versionIdMarker)

For internal use only. Sets the version ID marker parameter originally used to request this version listing.

Parameters:

versionIdMarker - The version ID marker parameter originally used to request this version listing.

getMaxKeys

public int getMaxKeys()

Gets the value of the maxKeys parameter used to request this version listing. Returns the default maxKeys value provided by Qcloud COS if no parameter value was otherwise specified.

The maxKeys parameter limits the number of versions included in this version listing. A version listing will never contain more versions than indicated by maxKeys , but can contain less.

Returns:

The value of the maxKeys parameter used to request this version listing. Returns the default maxKeys value provided by Qcloud COS if no parameter value was otherwise specified.

setMaxKeys

public void setMaxKeys(int maxKeys)

For internal use only. Sets the maxKeys parameter originally used to request this object listing, or the default maxKeys applied by Qcloud COS if the requester didn't specify a value.

Parameters:

maxKeys - The maxKeys parameter originally used to request this version listing, or the default maxKeys value applied by Qcloud COS if the requester didn't specify a value.

getDelimiter

public String getDelimiter()

Gets the value of the delimiter parameter used to request this version listing. Returns null if no parameter value was otherwise specified.

The delimiter value allows callers to condense COS keys into common prefix listings. For example, if a caller specifies a delimiter of "/" (a common used value for delimiter), then any keys that contain a common prefix between the start of the key and the first occurrence of "/" will not be included in the list of object summaries; instead, the common prefixes list will have one entry for the common prefix.

Returns:

The delimiter parameter originally used to request this version listing, or null if none was specified.

setDelimiter

public void setDelimiter(String delimiter)

For internal use only. Sets the delimiter parameter originally used to request this version listing.

Parameters:

delimiter - The delimiter parameter originally used to request this version listing.

getNextKeyMarker

public String getNextKeyMarker()

Gets the key marker to use in the next listVersions request in order to obtain the next page of results. Returns null if the version listing is not truncated. For truncated requests, this value is equal to the greatest (lexicographically) value of the object keys included in this listing.

Returns:

The key marker to use in the next listVersions request in order to obtain the next page of results. Returns null if the version listing is not truncated.

isTruncated()

setNextKeyMarker

public void setNextKeyMarker(String marker)

For internal use only. Sets the key marker to use in the next listVersions request in order to see the next page of results for a truncated version listing.

Parameters:

marker - The key marker to use in the next listVersions request in order to see the next page of results for a truncated version listing.

getNextVersionIdMarker

public String getNextVersionIdMarker()

Gets the version ID marker to use in the next listVersions request in order to obtain the next page of results. Returns null if the version listing is not truncated.

Returns:

The version ID marker to use in the next listVersions request in order to see the next page of results. Returns null if the version listing is not truncated.

See Also:

isTruncated()

For internal use only. Sets the version ID marker to use in the next listVersions request in order to see the next page of results for a truncated version listing.

Parameters:

marker - The version ID marker to use in the next listVersions request in order to obtain the next page of results for a truncated version listing.

isTruncated

public boolean isTruncated()

Gets whether or not the version listing is complete, indicating if additional calls to Qcloud COS are needed to obtain complete version listing results.

The value true if this version listing is not complete, indicating additional calls to Qcloud COS are needed to obtain complete version listing results. Returns the value false if otherwise.

setTruncated

public void setTruncated(boolean isTruncated)

For internal use only. Sets the truncated property for this version listing, indicating if this is a complete listing or not and whether the caller needs to make additional calls to COS to get more version summaries.

Parameters:

isTruncated - True if this version listing is not complete and the caller needs to make additional COS calls to get additional version summaries.

getEncodingType

public String getEncodingType()

Gets the encoding type used by Qcloud COS to encode object key names in the XML response. If you specify encodingType request parameter, Qcloud COS includes this element in the response, and returns encoded key name values in the following response elements: KeyMarker, NextKeyMarker, Prefix, Key, Delimiter.

Returns:

Null if encodingType is not specified in the request parameter.

setEncodingType

public void setEncodingType(String encodingType)

For internal use only. Sets the encoding type used by Qcloud COS to encode object key names in the XML response.
