indexOfType

public int indexOfType(java.lang.Class<? extends Filter> filterType)

Get the index of Filter in chain, which type is filterType, or -1 if the Filter of required type was not found.

Specified by:

indexOfType in interface FilterChain

Parameters:

filterType - the type of Filter to search.

Returns:

the index of Filter in chain, which type is filterType, or -1 if the Filter of required type was not found.

isInterested
