|
CalculateHash(String)
|
Overloaded. Calculates a hash code for the string.
 Note
|
This may produce identical keys for strings 16 characters and longer even though the input strings are unique, but is faster for large strings. If you want to ensure unique hashes for long string, use the overloaded CalculateHash function with Skip = 1
|
|
|
CalculateHash(String,Integer)
|
Overloaded. Calculates a hash code for the string.
Note
|
If the Skip parameter is greater than 1, this may produce identical keys for strings 16 characters and longer even though the input strings are unique, but is faster for large strings.
|
|
|
ClonePersistentClass(TPersistent,TClass)
|
Creates a copy of the source
Note
|
This method uses the Assign method to copy the old object's fields to the clone. If the Assign method is not implemented, the two objects will not equal.
|
|
|

|
|

|
|
GetSelStart(String,Integer)
|
Overloaded. Returns the position in the input string taken from RichEdit.Text of the Index line, useful for moving SelStart with TRichEdit, etc.
 Warning
|
Because Delphi 2009 uses RichEdit 2.0, use this GetSelStart function instead of GetSelStart( TSTRINGS, INTEGER )
|
|
|
GetSelStart(TStrings,Integer)
|
Overloaded. Returns the position in the input TStrings taken from RichEdit.Lines property of the Index line, useful for moving SelStart with TRichEdit, etc.
Warning
|
For Delphi 2009+, please use the GetSelStart function instead
|
|
|
GetSelStartIndex(String,Integer)
|
Overloaded. Returns the index of the line (obtained from a TRichEdit.Text property) which contains the selstart character
Warning
|
Because Delphi 2009 uses RichEdit 2.0, use this GetSelStart function instead of GetSelStartIndex( TSTRINGS, INTEGER )
|
|
|
GetSelStartIndex(TStrings,Integer)
|
Overloaded. Returns the index of the Strigns (obtained from a TRichEdit.Lines property) which contains the selstart character
Warning
|
For Delphi 2009+, please use the GetSelStartIndex function instead
|
|
|
GetStrCompareFunction(Boolean,TCompareStringsOption)
|
Returns a string comparison function that can compare two strings in the desired manner
|
|
ImportClassDeclFromFile(TStrings,String,TmwCachedPasLex)
|
Parses a .pas file and fills the Strs TStringList with a list of classes in the file and their declared ancestor classes, e.g.,
Delphi
|
TClass = class(TAncestorClass)

IsMatchStr(TCompareStringsOption,String,String,Integer)
|
Returns true if Title contains at the correct location the text string, case sensitive comparisons are used
|
|
IsMatchText(TCompareStringsOption,String,String,Integer)

|
|
IsNumberSymbol(Char)
|
Returns true if the input character is a symbol used in a number ('+', '-', '.')
|
|
PDiv(Double,Double,Double)
|
Overloaded. Performs a protected (i.e., no divide by zero error) division of two double precision, floating point numbers.
Divides v1 by v2, i.e., v1/v2. If v2 is 0, the function returns the DivZero parameter value.
|
|
PDiv(Extended,Extended,Extended)
|
Overloaded. Performs a protected (i.e., no divide by zero error) division of two extended precision, floating point numbers.
Divides v1 by v2, i.e., v1/v2. If v2 is 0, the function returns the DivZero parameter value.
|
|
PDiv(Single,Single,Single)
|
Overloaded. Performs a protected (i.e., no divide by zero error) division of two single precision, floating point numbers.
Divides v1 by v2, i.e., v1/v2. If v2 is 0, the function returns the DivZero parameter value.
