Field Details

pool

protected final URI.URIPool pool

This unit's pool.

value

protected String value

The value being accessed.

findHashCode

protected int findHashCode

The cached hash code computed by findMajorSeparator(int, String, int) and findSegmentEnd(int, String, int).

findTerminatingCharacter

protected char findTerminatingCharacter

The cached terminating character computed by findMajorSeparator(int, String, int) and findSegmentEnd(int, String, int).

stringArraySubstringAccessUnit

protected SegmentSequence.StringArrayPool.SubstringAccessUnit stringArraySubstringAccessUnit

An access unit for exclusive use in internArray(String, int, int, int).

stringArraySegmentsAndSubsegmentAccessUnit

protected SegmentSequence.StringArrayPool.SegmentsAndSubsegmentAccessUnit stringArraySegmentsAndSubsegmentAccessUnit

An access unit for exclusive use in internArray(int, String[], int, String, int, int, int).

Constructor Details

StringAccessUnit

protected StringAccessUnit(URI.URIPool.StringAccessUnit.Queue queue,
 URI.URIPool pool)

Creates an instance managed by this queue and pool.

Method Details

internArray

protected String[] internArray(String segment,
 int offset,
 int count,
 int hashCode)

internArray

protected String[] internArray(int hashCode,
 String[] segments,
 int segmentCount,
 String segment,
 int offset,
 int count,
 int segmentHashCode)

setValue

protected void setValue(String value)

Caches the parameters.

setValue

protected void setValue(String value,
 int hashCode)

Caches the parameters.

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>

match

public URI match()

Description copied from class: Pool.AccessUnit

Used to return a value from among the Pool.AccessUnit.values that Pool.AccessUnit.matches(Object) the value being accessed. Returns null if there is no such matching value.

Overrides:

match 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>

parseIntoURI

protected URI parseIntoURI(String uri)

A string-parsing implementation. This method creates instances in the pool as a side-effect. Note that we never pass in a string with a fragment separator to this method.

findMajorSeparator

protected int findMajorSeparator(int length,
 String s,
 int i)

Looks for a '/', ':', or '?', computing the hash code and setting the character that terminated the scan.

findSegmentEnd

protected int findSegmentEnd(int length,
 String s,
 int i)

Looks for a '/', or '?', computing the hash code and setting the character that terminated the scan.

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
