Selections

Interface - de.spieleck.app.jacson.JacsonSelect

The two filters SelectionExtractFilter ant SelectionFilterFilter are actually meta filters. Their behaviour can be heavily customized by another layer of plugin classes, Selections.

Selections localize certain pieces within a chunk. These pieces are taken by above filters and made available to make up a fresh chunk sequence with all possibilities for chunk processing provided by Jacson

The following selections are currently provided by Jacson in the package de.spieleck.app.jacson.select:

ParameterSelect

Selects the content of the selection into a JacsonStateParameter to be later reused by other Selections, Filters, reports or whatever.

RegExpGroupSelect

Picks up a range of characters determined by the groupings in a regular expression.

SubstringSelect

Picks up a range of characters determined by start and end (like Java String.substring()).

TokenSelect

Picks (Ant like) Tokens from a chunk, that is pieces of string which are prefixed by a customizable sequence and postfixed by a different sequence. Both sequences default to "@" to mimic Ants token filter mechanism.

WordSelect

The word select breaks a chunk into words separated by a certain set of delimiters. The delimiters default to whitespace and other grammatical word separations but can be customized.
