java.lang.Object | +--com.ibm.net.ssl.internal.www.protocol.https.RegexpPool
A class to represent a pool of regular expressions. A string can be matched against the whole pool all at once. It is much faster than doing individual regular expression matches one-by-one.

|
Method Summary | |
void |
add(java.lang.String re,
java.lang.Object ret)
Add a regular expression to the pool of regular expressions. |
java.lang.Object |
delete(java.lang.String re)
Delete the regular expression and its target. |
static void |
main(java.lang.String[] argv)
|
java.lang.Object |
match(java.lang.String s)
Search for a match to a string & return the object associated with it with the match. |
java.lang.Object |
matchNext(java.lang.String s)
Identical to match except that it will only find matches to regular expressions that were added to the pool after the last regular expression that matched in the last call to match() or matchNext() |
void |
print(java.io.PrintStream out)
Print this pool to standard output |
void |
replace(java.lang.String re,
java.lang.Object ret)
Replace the target for the regular expression with a different target. |
void |
reset()
Resets the pool so that the next call to matchNext looks at all regular expressions in the pool. |

re
- The regular expression to add to the pool.
For now, only handles strings that either begin or end with
a '*'.ret
- The object to be returned when this regular expression is
matched. If ret is an instance of the RegexpTarget class, ret.found
is called with the string fragment that matched the '*' as its
parameter.public void replace(java.lang.String re, java.lang.Object ret)
re
- The regular expression to be replaced in the pool.

public void reset()
Multithreading note: reset/nextMatch leave state in the regular expression pool. If multiple threads could be using this pool this way, they should be syncronized to avoid race hazards. match() was done in such a way that there are no such race hazards: multiple threads can be matching in the same pool simultaneously.
