Method Summary

Modifier and Type	Method	Description
static LogicalPathMapper	conservativePercentEncodingMapper()	Creates a percent-encoding that percent-encodes every character except: [a-zA-Z0-9_-].
static LogicalPathMapper	directMapper()	Creates a LogicalPathMapper that directly maps logical paths to content paths, making no changes.
static LogicalPathMapper	percentEncodingAllMapper()	Creates a percent-encoding that encodes the following characters that are generally problematic across Windows, linux, and cloud platforms: ASCII characters codes: x0-x1f ASCII characters codes: x7f-xa0 Characters: <>:"\|?* #[]
static LogicalPathMapper	percentEncodingCloudMapper()	Creates a percent-encoding that encodes the following characters that are problematic for some cloud storage platforms: ASCII characters codes: x0-x1f ASCII characters codes: x7f-xa0 Characters: \#[]*?

Method Detail

directMapper

public static LogicalPathMapper directMapper()

Creates a LogicalPathMapper that directly maps logical paths to content paths, making no changes.

Returns:

mapper

percentEncodingWindowsMapper

public static LogicalPathMapper percentEncodingWindowsMapper()

Creates a percent-encoding mapper that encodes the following characters that are problematic for Windows:

• ASCII characters codes: x0-x1f
• ASCII characters codes: x7f-xa0
• Characters: <>:"\|?*

This should produce generally safe content paths, but they are not guaranteed safe.

Returns:

mapper

percentEncodingLinuxMapper

public static LogicalPathMapper percentEncodingLinuxMapper()

Creates a percent-encoding that encodes the following characters:

• ASCII characters codes: x0-x1f
• ASCII characters codes: x7f-xa0
• Characters:

Linux is extremely permissive when it comes to the characters that are allowed in filenames. Some of the characters encoded here are in fact legal. However, it is often undesirable for them to appear in filenames.

Returns:

mapper

percentEncodingCloudMapper

public static LogicalPathMapper percentEncodingCloudMapper()

Creates a percent-encoding that encodes the following characters that are problematic for some cloud storage platforms:

• ASCII characters codes: x0-x1f
• ASCII characters codes: x7f-xa0
• Characters: \#[]*?

This should produce generally safe content paths, but they are not guaranteed safe.

Returns:

mapper

percentEncodingAllMapper

public static LogicalPathMapper percentEncodingAllMapper()

Creates a percent-encoding that encodes the following characters that are generally problematic across Windows, linux, and cloud platforms:

• ASCII characters codes: x0-x1f
• ASCII characters codes: x7f-xa0
• Characters: <>:"\|?* #[]

This should produce generally safe content paths, but they are not guaranteed safe.

Returns:

mapper

conservativePercentEncodingMapper

public static LogicalPathMapper conservativePercentEncodingMapper()

Creates a percent-encoding that percent-encodes every character except: [a-zA-Z0-9_-].

This is an extremely conservative mapper that will produce content paths without problematic characters. However, it will also greatly inflate the size of the paths, potentially making them longer than the filesystem's filename size limit.

Returns:

mapper
