public GcsResourceId resolve(java.lang.String other, ResolveOptions resolveOptions)
ResourceId
ResourceId
under this
.
In order to write file system agnostic code, callers should not include delimiters in other
, and should use ResolveOptions.StandardResolveOptions
to specify whether to resolve a file or a
directory.
For example:
ResourceId homeDir = ...;
ResourceId tempOutput = homeDir
.resolve("tempDir", StandardResolveOptions.RESOLVE_DIRECTORY)
.resolve("output", StandardResolveOptions.RESOLVE_FILE);
This ResourceId
should represents a directory.
It is up to each file system to resolve in their own way.
Resolving special characters:
resourceId.resolve("..", StandardResolveOptions.RESOLVE_DIRECTORY)
returns the
parent directory of this ResourceId
.
resourceId.resolve("*", StandardResolveOptions.RESOLVE_FILE)
returns a ResourceId
which matches all files in this ResourceId
.
resourceId.resolve("*", StandardResolveOptions.RESOLVE_DIRECTORY)
returns a
ResourceId
which matches all directories in this ResourceId
.
