getCamelCaseMatchingRegions

public static final int[] getCamelCaseMatchingRegions(String pattern,
 int patternStart,
 int patternEnd,
 String name,
 int nameStart,
 int nameEnd,
 boolean samePartCount)

Answers all the regions in a given name matching a given camel case pattern.

Each of these regions is made of its starting index and its length in the given name. They are all concatenated in a single array of int which therefore always has an even length.

Note that each region is disjointed from the following one.
E.g. if the regions are { start1, length1, start2, length2 }, then start1+length1 will always be smaller than start2.

 Examples:
 
  pattern = "NPE"
  name = NullPointerException / NoPermissionException
  result:  { 0, 1, 4, 1, 11, 1 } / { 0, 1, 2, 1, 12, 1 } 
 
  pattern = "NuPoEx"
  name = NullPointerException
  result:  { 0, 2, 4, 2, 11, 2 }
 
  pattern = "IPL3"
  name = "IPerspectiveListener3"
  result:  { 0, 2, 12, 1, 20, 1 }
 
  pattern = "HashME"
  name = "HashMapEntry"
  result:  { 0, 5, 7, 1 }
 

Parameter:

pattern - the given pattern

patternStart - the start index of the pattern, inclusive

patternEnd - the end index of the pattern, exclusive

name - the given name

nameStart - the start index of the name, inclusive

nameEnd - the end index of the name, exclusive

samePartCount - flag telling whether the pattern and the name should have the same count of parts or not.
For example:

• 'HM' type string pattern will match 'HashMap' and 'HtmlMapper' types, but not 'HashMapEntry'
• 'HMap' type string pattern will still match previous 'HashMap' and 'HtmlMapper' types, but not 'HighMagnitude'

Gibt zurück:

an array of int having two slots per returned regions (first one is the starting index of the region and the second one the length of the region).
Note that it may be null if the given name does not match the pattern

getPatternMatchingRegions

public static final int[] getPatternMatchingRegions(String pattern,
 int patternStart,
 int patternEnd,
 String name,
 int nameStart,
 int nameEnd,
 boolean isCaseSensitive)

Answers all the regions in a given name matching a given pattern pattern (e.g. "H*M??").

Each of these regions is made of its starting index and its length in the given name. They are all concatenated in a single array of int which therefore always has an even length.

Note that each region is disjointed from the following one.
E.g. if the regions are { start1, length1, start2, length2 }, then start1+length1 will always be smaller than start2.

 Examples:
 

 
  pattern = "N???Po*Ex?eption"
  name = NullPointerException
  result:  { 0, 1, 4, 2, 11, 2, 14, 6 }
 
  pattern = "Ha*M*ent*"
  name = "HashMapEntry"
  result:  { 0, 2, 4, 1, 7, 3 }
 

Parameter:

pattern - the given pattern

patternStart - the given pattern start

patternEnd - the given pattern end

name - the given name

nameStart - the given name start

nameEnd - the given name end

isCaseSensitive - flag to know if the matching should be case sensitive

Gibt zurück:

an array of int having two slots per returned regions (first one is the starting index of the region and the second one the length of the region).
Note that it may be null if the given name does not match the pattern
