The optional convenience implementation of the locator.

This class is available mainly for application writers, who can use it to make a persistent snapshot of a locator at any point during a document reding session:

Normally, reader developers will not use this class, since it is more efficient to provide location information only when requested, rather than constantly updating a locator object.

1.00.00

CLocator

CLocatorImpl

CLocatorImpl();

Constructs the locator.

This is a zero-argument constructor.

This will not normally be useful, since the main purpose of this class is to make a snapshot of an existing locator.

CLocatorImpl

CLocatorImpl(CLocator *pLocator);

Constructs the locator.

This is a copy constructor.

It creates a persistent copy of the current state of a locator. When the original locator changes, this copy will still keep the original values (and it can be used outside the scope of document handler methods).

Parameters:

pLocator - the locator to copy

~CLocatorImpl

~CLocatorImpl();

Destroys the locator.

GetPublicId

const WCHAR *GetPublicId();

Gets the saved public identifier.

Returns:

the public identifier as a string, or the empty string if none is available

GetSystemId

const WCHAR *GetSystemId();

Gets the saved system identifier.

Returns:

the system identifier as a string, or the empty string if none is available

GetLineNumber

int GetLineNumber();

Gets the saved line number (1-based).

Returns:

the line number as an integer, or -1 if none is available

GetColumnNumber

int GetColumnNumber();

Gets the saved column number (1-based).

Returns:

the column number as an integer, or -1 if none is available

SetPublicId

void SetPublicId(const WCHAR *pszPublicId);

Sets the public identifier for this locator.

Parameters:

pszPublicId - the new public identifier, or the empty string if none is available

SetSystemId

void SetSystemId(const WCHAR *pszSystemId);

Sets the system identifier for this locator.

Parameters:

pszSystemId - the new system identifier, or the empty string if none is available

SetLineNumber

void SetLineNumber(int nLineNumber);

Sets the line number for this locator (1-based).

Parameters:

nLineNumber - the line number, or -1 if none is available

SetColumnNumber

void SetColumnNumber(int nColumnNumber);

Sets the column number for this locator (1-based).

Parameters:

nColumnNumber - the column number, or -1 if none is available
