Class RStringPool

class RStringPool;

Description

String pool handle.

A string pool can have several distinct handles associated with it, each associated with a different pre-loaded table. Creating a string from an enum value interprets the value as an offset into the relevant pre-loaded table.

Members

Defined in RStringPool:
Close(), OpenFStringL(), OpenL(), OpenL(), OpenL(), OpenStringL(), RStringPool(), String(), String(), StringF(), StringF()

inline RStringPool();

Description

Default constructor.

IMPORT_C void OpenL(const TStringTable &aTable);

Description

Creates an initialised string pool with a pre-loaded string table.

Parameters

const TStringTable &aTable The pre-loaded string table.

IMPORT_C void OpenL(const TStringTable &aTable, MStringPoolCloseCallBack &aCallBack);

Description

Creates an initialised string pool with a pre-loaded string table, and a string-pool-closing callback.

Parameters

const TStringTable &aTable The pre-loaded string table. MStringPoolCloseCallBack &aCallBack Callback interface that is called when the string pool closes

KErrNoMemory Not enough memory to open the pool

IMPORT_C void Close();

Description

Closes the string pool table.

This invalidates all other handles to the table.

IMPORT_C RStringF OpenFStringL(const TDesC8 &aString) const;

Description

Creates an RStringF using the current string pool.

The string is opened as case-insensitive.

Parameters

const TDesC8 &aString The value of the string.

Return value

RStringF Initialised RStringF object

Leave codes

KErrNoMemory Not enough memory to open the string

IMPORT_C RString OpenStringL(const TDesC8 &aString) const;

Description

Creates an RString using the current string pool.

The string is opened as case-sensitive.

Parameters

const TDesC8 &aString The value of the string.

Return value

RString Initialised RString object

Leave codes

KErrNoMemory Not enough memory to open the string

IMPORT_C RString String(RStringToken aString) const;

Description

Creates an RString from the supplied RStringToken.

Parameters

RStringToken aString The string token

Return value

RString Initialised RString object

IMPORT_C RString String(TInt aIndex, const TStringTable &aTable) const;

Description

Gets a case-sensitive string specified by a string table enumeration value.

aIndex is interpreted as an offset into the handle's pre-loaded string table.

Parameters

TInt aIndex The string table enumeration value const TStringTable &aTable The string table from which to read the string

Return value

RString Initialised RString object

Panic codes

EStringTableNotFound If the table supplied is not found. This panic is raised in debug builds only, in release mode the behaviour is undefined

IMPORT_C RStringF StringF(RStringTokenF aString) const;

Description

Creates a RStringF from the supplied RStringToken.

Parameters

RStringTokenF aString The value of the string

Return value

RStringF Initialised RStringF object

IMPORT_C RStringF StringF(TInt aIndex, const TStringTable &aTable) const;

Description

Gets a case-insensitive string specified by a string table enumeration value.

Creates an RStringF from a string table enumeration value.

aIndex is interpreted as an offset into the handle's pre-loaded string table.

Parameters

TInt aIndex The string table enumeration value const TStringTable &aTable The string table from which to read the string

Return value

RStringF Initialised RStringF object

Panic codes

EStringTableNotFound If the table supplied is not found. This panic is raised in debug builds only, in release mode the behaviour is undefined
