Package com.aoapps.net.partialurl

Class PartialURL

java.lang.Object

com.aoapps.net.partialurl.PartialURL

Direct Known Subclasses:

MultiPartialURL, SinglePartialURL

public abstract class PartialURL
extends Object

A PartialURL matches and completes URLs. All fields are optional.

This is not a general-purpose representation of a URL. It only contains the fields specifically used for matching a request to a virtual host (TODO: Links to projects). For an instance of URL, see toURL(com.aoapps.net.partialurl.FieldSource).

All partial URLs are immutable value types.

matches

public abstract SinglePartialURL matches(FieldSource fieldSource)
                                  throws MalformedURLException

Checks if the given FieldSource matches this partial URL.

The SinglePartialURL returned, if any, is also in the set of partial URLs provided by getCombinations(). Specifically, the match must be equivalent to the first match found by iterative calls to the results of getCombinations(), using SinglePartialURL.matches(com.aoapps.net.partialurl.FieldSource) on each single partial. The implementation, however, does not need to be iterative.

Ordering is consistent with:

• getCombinations()
• SinglePartialURL.compareTo(com.aoapps.net.partialurl.SinglePartialURL)
• PartialURLMap.get(com.aoapps.net.partialurl.FieldSource)

Parameters:

fieldSource - When all fields are null (this is DEFAULT), this is not used and may be null.

Returns:

The SinglePartialURL with non-null fields selected to match the field source, or null when does not match. When the match is equals the primary, returns the same object as getPrimary().

Throws:

MalformedURLException

isComplete

public abstract boolean isComplete()

Checks if this partial URL is complete (has no null fields other than prefix). A complete URL may be converted to a URL without any field source provided.

See Also:

• toURL(com.aoapps.net.partialurl.FieldSource)

getPrimary

public abstract SinglePartialURL getPrimary()

Gets the primary single partial URL for this partial URL.

This will always be found in getCombinations().

See Also:

• getCombinations()

getCombinations

public abstract Iterable<SinglePartialURL> getCombinations()

Gets all combinations of single partial URLs represented by this partial URL.

Ordering is consistent with:

• matches(com.aoapps.net.partialurl.FieldSource)
• SinglePartialURL.compareTo(com.aoapps.net.partialurl.SinglePartialURL)
• PartialURLMap.get(com.aoapps.net.partialurl.FieldSource)

When one of the results is equal to the primary, returns the same object instance as getPrimary().

See Also:

• getPrimary()
• SinglePartialURL.compareTo(com.aoapps.net.partialurl.SinglePartialURL)

toURL

public abstract URL toURL(FieldSource fieldSource)
                   throws MalformedURLException

Gets the general-purpose representation of URL for this partial URL.

Parameters:

fieldSource - Only used when at least one field is null and uses the value from the source. May be null when this PartialURL is known to have all fields specified.

Throws:

NullPointerException - when fieldSource not provided and at least one field is null.

MalformedURLException
