Method Detail

testNumberSubstitutionRegex

public void testNumberSubstitutionRegex()

The numberSubstitution regex:

$number

In this example we define the following match pattern:

\b(\w+)(\s)(\w+)\b

And the following substitution pattern:

$3$2$1

Using the String "one two" as input the following will happen:

"one" will be matched as the first group;

" " will be matched as the second group;

"two" will be matched as the third group;

Or:

$1 $2 $3

"one" " " "two"

Since the substitution pattern is "$3$2$1" the words will be rearranged and will generate the following String:

$3 $2 $1

"two" " " "one"

testNameSubstitutionRegex

public void testNameSubstitutionRegex()

The nameSubstitution regex:

${name}

In this example we define the following match pattern:

\b(?<word1>\w+)(\s)(?<word2>\w+)\b

And the following substitution pattern:

${word2} ${word1}

Using the String "one two" as input the following will happen:

"one" will be matched as the group word1;

" " will be matched as the second group;

"two" will be matched as the group word2;

Or:

word1 $2 word2

"one" " " "two"

Since the substitution pattern is "${word2} ${word1}" the words will be rearranged and will generate the following String:

word2 " " word1

"two" " " "one"
