function MamaRegexChannelFilter

inline MamaRegexChannelFilter()

Creates a MAMA regex filter to help filter strings into channels (ints). The channel itself has no special meaning - it’s simply a number to produce when each regular expression is matched.

The main use case is for load balancing dispatcher queues according to topic names.

function setDefaultChannel

inline void setDefaultChannel(
    int channelId
)

Parameters:

• channelId The channel to use when no matches are found

Sets a default channel to use if no filters produce hits during matching.

function addRegex

inline void addRegex(
    final String regexStr,
    final int channelId
)

Parameters:

• regexStr The regex string to add
• channelId The channel to route to for this regex

Adds a regex string and associated integer. During calls to getChannel, the target string will be matched against this regular expression to see which channel matches it.

function getChannel

inline int getChannel(
    final String target
)

Parameters:

• target The string to try matching according to

Looks up all channel filters to see which channel this target should be routed to.
