Field Details

FILE_BASE

protected static final String FILE_BASE

The base URI for file scheme URIs.

See Also:

• Constant Field Values

FILE_BASE_LENGTH

protected static final int FILE_BASE_LENGTH

The length of the base URI for file scheme URIs.

FILE_BASE_HASH_CODE

protected static final int FILE_BASE_HASH_CODE

The hash code of the base URI for file scheme URIs.

path

protected String path

The file path being accessed.

absoluteCharacters

protected char[] absoluteCharacters

The buffer for absolute file paths.

relativeCharacters

protected char[] relativeCharacters

The buffer for relative file paths.

segments

protected String[] segments

The segments of the path.

segmentCount

protected int segmentCount

The number of segments in the path.

usedSegmentCount

protected int usedSegmentCount

The number of segments populated with strings during intern that need to be nulled during reset.

segmentBoundaries

protected int[] segmentBoundaries

The boundaries of the segments in the path.

segmentHashCodes

protected int[] segmentHashCodes

The hash codes of the segments in the path.

encodedPath

protected String encodedPath

The final encoded path.

isAbsoluteFile

protected boolean isAbsoluteFile

Whether the file path represents an absolute file.

isAbsolutePath

protected boolean isAbsolutePath

Whether the path itself is absolute.

Constructor Details

FileAccessUnit

public FileAccessUnit(URI.URIPool.FileAccessUnit.Queue queue)

Creates an instance managed by the given queue.

Method Details

setValue

protected void setValue(String path)

Caches the parameter and computes the hash code.

matches

protected boolean matches(URI value)

Description copied from class: Pool.AccessUnit

Used to determine whether the given value from the pool is equal to the value being accessed. The default implementation uses Object.equals(Object).

Overrides:

matches in class Pool.AccessUnit<URI>

getInternalizedValue

public URI getInternalizedValue()

Description copied from class: Pool.AccessUnit

Gets the value that should be added to the pool. This can be specialized to internalized the value, e.g., to make a copy that uses minimal storage or is read only.

Overrides:

getInternalizedValue in class Pool.AccessUnit<URI>

reset

public void reset(boolean isExclusive)

Description copied from class: Pool.AccessUnit

Prepare the access unit for reuse. In particular remove the hard references to each element in both the Pool.AccessUnit.values and Pool.AccessUnit.entries and then reset the Pool.AccessUnit.valuesLength to 0

Overrides:

reset in class URI.URIPool.URIPoolAccessUnitBase
