TypeDescription
CloudStorageConfiguration

Static Methods

builder()

public static CloudStorageConfiguration.Builder builder()

Creates a new builder, initialized with the following settings:

  • Performing I/O on paths with extra slashes, e.g. a//b will throw an error.
  • The prefix slash on absolute paths will be removed when converting to an object name.
  • Pseudo-directories are enabled, so any path with a trailing slash is a fake directory.
  • Channel re-opens are disabled.
Returns
TypeDescription
CloudStorageConfiguration.Builder

Methods

blockSize()

public abstract int blockSize()

Returns block size (in bytes) used when talking to the Google Cloud Storage HTTP server.

Returns
TypeDescription
int

maxChannelReopens()

public abstract int maxChannelReopens()

Returns the number of times we try re-opening a channel if it's closed unexpectedly while reading.

Returns
TypeDescription
int

permitEmptyPathComponents()

public abstract boolean permitEmptyPathComponents()

Returns true if we shouldn't throw an exception when encountering object names containing superfluous slashes, e.g. a//b.

Returns
TypeDescription
boolean

reopenableExceptions()

public abstract ImmutableList<Class<? extends Exception>> reopenableExceptions()

Returns the set of exceptions for which we'll try a channel reopen if maxChannelReopens is positive.

Returns
TypeDescription
com.google.common.collect.ImmutableList<Class<? extends java.lang.Exception>>

retryableHttpCodes()

public abstract ImmutableList<Integer> retryableHttpCodes()

Returns the set of HTTP error codes that will be retried, in addition to the normally retryable ones.

Returns
TypeDescription
com.google.common.collect.ImmutableList<Integer>

stripPrefixSlash()

public abstract boolean stripPrefixSlash()

Returns true if '/' prefix on absolute object names should be removed before I/O.

If you disable this feature, please take into consideration that all paths created from a URI will have the leading slash.

Returns
TypeDescription
boolean

usePseudoDirectories()

public abstract boolean usePseudoDirectories()

Returns true if directories and paths with a trailing slash should be treated as fake directories.

With this feature, if file "foo/bar.txt" exists then both "foo" and "foo/" will be treated as if they were existing directories. On path construction no I/O will be performed, bucket and "directory" will treated as if they exist.

Returns
TypeDescription
boolean

useUserProjectOnlyForRequesterPaysBuckets()

public abstract boolean useUserProjectOnlyForRequesterPaysBuckets()

Returns whether userProject will be cleared for non-requester-pays buckets. That is, if false (the default value), setting userProject causes that project to be billed regardless of whether the bucket is requester-pays or not. If true, setting userProject will only cause that project to be billed when the project is requester-pays.

Setting this will cause the bucket to be accessed when the CloudStorageFileSystem object is created.

Returns
TypeDescription
boolean

userProject()

public abstract String userProject()

Returns the project to be billed when accessing buckets. Leave empty for normal semantics, set to bill that project (project you own) for all accesses. This is required for accessing requester-pays buckets. This value cannot be null.

Returns
TypeDescription
String

workingDirectory()

public abstract String workingDirectory()

Returns path of current working directory. This defaults to the root directory.
