C# Class Gammtek.Conduit.Text.Formatting.FormatInfoUtils

Stateless static class which exposes methods used to help format strings. This class is internal and cannot be used directly. It is rather used by other classes declared in the SysExpand.Text.Formatting namespace to help format strings.

Méthode	Description
BestTryFormat ( StringBuilder sb, string format, object arg, IEnumerable formatProviders, int &maxLength ) : bool	Attempts to format string which represents given object using series of verbose format providers. Operation ends in success when the first available format provider successfully formats the string. Operation ends in failure if none of the format providers is able to successfully format the string. Use this method to implement two-pass formatting, where in first pass single-lined formatting is attempted with restricted destination string length and in second pass multi-lined formatting without length restrictions is performed.
CombineMaxFormattedLengths ( int length1, int length2 ) : int	Combines two values of the maximum allowed formatted string length.
CopyFormatting ( VerboseFormatInfoBase src, VerboseFormatInfoBase dest ) : VerboseFormatInfoBase	Copies formatting-related property values from one verbose formatter to another one. Use this method to change active formatter so that it formats string in the way in which other formatter would do, but preserving other settings, like indentation details, maximum depth when recursively iterating through contents of the object etc.
CreateMultiLinedFormatter ( ) : VerboseFormatInfoBase	Creates new instance of verbose formatter which can be applied to format multi-lined string without any decorations. This format is applicable to objets of medium complexity. Indentation is performed using multiple whitespace characters.
CreateSimpleFormatter ( ) : VerboseFormatInfoBase	Creates new instance of verbose formatter which can be applied to format simplest possible strings. Only the first level of depth is presented in the formatted string and format is single-lined. This format is applicable to objects of unpredictable complexity, which should be presented by strings of limited length.
CreateSingleLinedFormatter ( ) : VerboseFormatInfoBase	Creates new instance of verbose formatter which formats single-lined strings.
CreateTabbedMultiLinedFormatter ( ) : VerboseFormatInfoBase	Creates new instance of verbose formatter which can be applied to format multi-lined strings without any decorations. This format is applicable to objects of medium complexity. Indentation is performed using horizontal tab characters.
CreateTreeMultiLinedFromatter ( ) : VerboseFormatInfoBase	Creates new instance of verbose formatter which can be applied to format multi-lined string which is decorated as to resemble the look of a tree structure. This format is applicable to complex objects.
ReportInfiniteLoop ( StringBuilder sb, object arg, string argName, int &maxLength ) : bool	Appends information that specified argument produces infinite loop to the given string builder.
TryAppendChar ( VerboseFormatInfoBase formatter, StringBuilder sb, char c, bool success, int &maxLength ) : bool	Tries to append character to the string builder within given amount of characters allowed. Always succeeds in multi-lined formatters.
TryAppendSpaceIfNeeded ( VerboseFormatInfoBase formatter, StringBuilder sb, bool success, int &maxLength ) : bool	Tries to append single white space if string builder doesn't end with space or new line character. Use this method to separate successive items appended to string builder.
TryAppendString ( VerboseFormatInfoBase formatter, StringBuilder sb, string s, bool success, int &maxLength ) : bool	Tries to append string to the string builder within given amount of characters allowed. Always succeeds in multi-lined formatters.

Method Details

BestTryFormat() public static méthode

Attempts to format string which represents given object using series of verbose format providers. Operation ends in success when the first available format provider successfully formats the string. Operation ends in failure if none of the format providers is able to successfully format the string. Use this method to implement two-pass formatting, where in first pass single-lined formatting is attempted with restricted destination string length and in second pass multi-lined formatting without length restrictions is performed.

public static BestTryFormat ( StringBuilder sb, string format, object arg, IEnumerable formatProviders, int &maxLength ) : bool
sb	StringBuilder	String builder to which formatted string is appended.
format	string	Format string containing formatting specifications.
arg	object	An object to format.
formatProviders	IEnumerable	/// Series of format providers which are contacted one at a time until the first performs /// formatting successfully. ///
maxLength	int	/// Maximum number of characters allowed to the formatter. Formatting will fail (and return false) /// if this number of characters is breached. Multi-lined formatters will ignore this parameter. /// Negative value indicates that formatter has unlimited space available. /// On output contains remaining number of characters available. ///
Résultat	bool

CombineMaxFormattedLengths() public static méthode

Combines two values of the maximum allowed formatted string length.

public static CombineMaxFormattedLengths ( int length1, int length2 ) : int
length1	int	First maximum formatted string length; negative value indicates infinite allowed length.
length2	int	Second maximum formatted string length; negative value indicates infinite allowed length.
Résultat	int

CopyFormatting() public static méthode

Copies formatting-related property values from one verbose formatter to another one. Use this method to change active formatter so that it formats string in the way in which other formatter would do, but preserving other settings, like indentation details, maximum depth when recursively iterating through contents of the object etc.

public static CopyFormatting ( VerboseFormatInfoBase src, VerboseFormatInfoBase dest ) : VerboseFormatInfoBase
src	VerboseFormatInfoBase	Formatter from which formatting property values are copied.
dest	VerboseFormatInfoBase	Formatter into which formatting property values are copied.
Résultat	VerboseFormatInfoBase

CreateMultiLinedFormatter() public static méthode

CreateSimpleFormatter() public static méthode

Creates new instance of verbose formatter which can be applied to format simplest possible strings. Only the first level of depth is presented in the formatted string and format is single-lined.
