Constructor Details

URIPool

public URIPool(ReferenceQueue<Object> queue)

Method Details

intern

protected URI intern(String string)

Intern a URI from its string representation, parsing if necessary. The string must not contain the fragment separator.

intern

protected URI intern(String base,
 String pathName,
 boolean encode)

Intern a platform URI from its path representation, parsing if necessary.

internFile

protected URI internFile(String pathName)

Intern a file URI from its path representation, parsing if necessary.

intern

protected URI intern(boolean isExclusive,
 int validate,
 boolean hierarchical,
 String scheme,
 String authority,
 String device,
 boolean absolutePath,
 String[] segments,
 String query)

Intern a URI from its component parts. If isExclusive is true, acquire the Pool.writeLock first. Use intern(boolean, boolean, String, String, String, boolean, String[], String, int) if the hash code is known and no validation is required.

intern

protected URI intern(boolean isExclusive,
 boolean hierarchical,
 String scheme,
 String authority,
 String device,
 boolean absolutePath,
 String[] segments,
 String query,
 int hashCode)

Intern a URI from its component parts. If isExclusive is true, acquire the Pool.writeLock first.

doCleanup

protected void doCleanup()

Specialized to manage the cachedToStrings.

Overrides:

doCleanup in class Pool<URI>

newCachedToString
