Method Detail

getSubset

public static final Map<String,String> getSubset(Map<String,String> params,
                           String prefix,
                           boolean evalValues)

Given a map of parameters and a prefix, this method will return a map with the subset of parameters that match the given prefix. Not that a '.' will be automatically added to the prefix, and the prefix will be remoevd from the resulting map. I.e. if prefix is 'myPfx', and the map contains keys 'myPfx', 'myPfx.a', 'myPfx.b' and 'xxx', then this method will return a map with keys 'a' and 'b'. If the evalValues flag is set to true, then any expressions contained in the parameter value will be evaluated; see ExpressionUtil.

Parameters:

params -

prefix -

evalValues -

Returns:
