Class TParsePtrC

class TParsePtrC : public TParseBase;

Description

Parses, but cannot modify, filenames using less space on the stack than TParse.

Stores a reference to a filename, unlike TParse, which uses a 512 byte TFileName object as an internal buffer to store a copy of the filename. The filename's components (drive, path, etc.) can be retrieved using the functions provided by the base class, TParseBase. Note that because the filename cannot be modified through this class, the base class functions PopDir() and AddDir() cannot be called, because a panic will be raised.

Derivation

• TParseBase - Base class for file name parsing

• TParsePtrC - Parses, but cannot modify, filenames using less space on the stack than TParse

Members

Defined in TParsePtrC:

• NameBuf()Gets a reference to the descriptor containing the filename passed to the constructor of this object
• NameBufC()Gets a const reference to the descriptor containing the filename passed to the constructor of this object
• TParsePtrC()Constructor taking a constant reference to a filename

Inherited from TParseBase:

• AddDir()Adds a single directory onto the end of the path in the fully parsed specification
• Drive()Gets the drive letter
• DriveAndPath()Gets the drive letter and path
• DrivePresent()Tests whether a drive is present
• Ext()Gets the extension
• ExtPresent()Tests whether an extension is present
• FullName()Gets the complete file specification
• IsExtWild()Tests whether the extension in the fully parsed specification contains one or more wildcard characters
• IsKMatchAny()Tests whether the name or the extension contains asterisk wildcards
• IsKMatchOne()Tests whether the name or the extension contains a question mark wildcard
• IsNameWild()Tests whether the filename in the fully parsed specification contains one or more wildcard characters
• IsRoot()Tests whether the path in the fully parsed specification is the root directory
• IsWild()Tests whether the filename or the extension in the fully parsed specification contains one or more wildcard characters
• Name()Gets the filename
• NameAndExt()Gets the filename and extension
• NameOrExtPresent()Tests whether a filename or an extension are present
• NamePresent()Tests whether a file name is present
• Path()Gets the path
• PathPresent()Tests whether a path is present
• PopDir()Removes the last directory from the path in the fully parsed specification
• iMod

IMPORT_C TParsePtrC(const TDesC &aName);

Description

Constructor taking a constant reference to a filename.

The filename is parsed and if this fails, a panic is raised. Note that the filename cannot be modified using this class.

Parameters

const TDesC &aName Constant reference to the filename to be parsed. On return contains the fully parsed filename. If a file and extension are specified, they may both contain wildcards. The maximum length is KMaxFileName characters.

Panic codes

FSCLIENT 24 if the the specified name fails to parse.

• KMaxFileNameDefines the maximum length of a filename

protected: virtual IMPORT_C TDes &NameBuf();

Description

Gets a reference to the descriptor containing the filename passed to the constructor of this object.

Return value

TDes & A reference to the descriptor containing the filename.

protected: virtual IMPORT_C const TDesC &NameBufC() const;

Description

Gets a const reference to the descriptor containing the filename passed to the constructor of this object.

Return value

const TDesC & A const reference to the descriptor containing the filename.
