TStringReplaceAlgorithm

Algorithm to use in StringReplace

Declaration

Source position: strutils.pp line 269

`type TStringReplaceAlgorithm = (`
`sraDefault,`		Use the sysutils algorithm, which does a straightforward linear search and replace
`sraManySmall,`		Use an approach which is suitable for a string with many occurrences of the same small text
`sraBoyerMoore`		Use a Boyer-Moore search algorithm
`);`

TStringReplaceAlgorithm enumerates the available algorithms to StringReplace

sraDefault: Use the sysutils algorithm, which does a straightforward linear search and replace
sraManySmall: Use an approach which is suitable for a string with many occurrences of the same small text
sraBoyerMoore: Use a Boyer-Moore search algorithm

Depending on the kind of data that is being treated, one or the other of these algorithms may produce faster results.
