The EReg class represents regular expressions.
While basic usage and patterns consistently work across platforms, some more complex operations may yield different results. This is a necessary trade- off to retain a certain level of performance.
EReg instances can be created by calling the constructor, or with the
special syntax ~/pattern/modifier
EReg instances maintain an internal state, which is affected by several of its methods.
A detailed explanation of the supported operations is available at https://haxe.org/manual/std-regex.html
Constructor
Methods
Tells if this
regular expression matches String s
.
This method modifies the internal state.
If s
is null
, the result is unspecified.
Available on Flash, HTML5
Returns the matched sub-group n
of this
EReg.
This method should only be called after this.match
or
this.matchSub
, and then operates on the String of that operation.
The index n
corresponds to the n-th set of parentheses in the pattern
of this
EReg. If no such sub-group exists, an exception is thrown.
If n
equals 0, the whole matched substring is returned.
Available on Flash
Returns the part to the right of the last matched substring.
If the most recent call to this.match
or this.matchSub
did not
match anything, the result is unspecified.
If the global g modifier was in place for the matching, only the substring to the right of the leftmost match is returned.
The result does not include the matched part.
