 net.sf.saxon.functions.Matches
| Matches | | public class Matches extends SystemFunction (Code) | | This class implements the matches() function for regular expression matching
|
| evaluateItem | | public Item evaluateItem(XPathContext c) throws XPathException(Code) | | Evaluate the matches() function to give a Boolean value.
Parameters:
c - The dynamic evaluation context the result as a BooleanValue, or null to indicate the empty sequence
throws:
XPathException - on an error |
| setFlags | | public static int setFlags(CharSequence inFlags) throws StaticError(Code) | | Set the Java flags from the supplied XPath flags.
Parameters:
inFlags - the flags as a string, e.g. "im" the flags as a bit-significant integer
throws:
net.sf.saxon.trans.StaticError - if the supplied value is invalid |
| tryToCompile | | protected static Pattern tryToCompile(Expression[] args, int patternArg, int flagsArg) throws StaticError(Code) | | Try to precompile the arguments to the function. This method is shared by
the implementations of the three XPath functions matches(), replace(), and
tokenize().
Parameters:
args - the supplied arguments to the function, as an array
Parameters:
patternArg - the position of the argument containing the regular expression
Parameters:
flagsArg - the position of the argument containing the flags the compiled regular expression, or null indicating that the informationis not available statically so it cannot be precompiled
throws:
net.sf.saxon.trans.StaticError - if any failure occurs, in particular, if the regularexpression is invalid |
