Method Summary

java.util.List<Span>	getSpans(java.lang.String text) Analyses a string and split it in parts.
java.util.List<java.lang.String>	getStrings(java.lang.String text, boolean asSubstring) Analyses a string and split it in parts.

Method Detail

getStrings

java.util.List<java.lang.String> getStrings(java.lang.String text,
                                            boolean asSubstring)

Analyses a string and split it in parts. The return value is a list of this parts as Strings, either as substrings or string copies dependent on asSubstring parameter.

Parameters:

text - The original text to decompose.

asSubstring - If true, returned strings in list are substrings of input text else explicit copies are returned. A substring is a pointer to the original string and start/end position. A string copy is an exact copy of the part.
If you are interested just in some parts of the text and don't want to hold the hole text in main memory, you might choose string copies.

Returns:

List of string, as substrings or string copies dependent on asSubstring parameter.
