public static ExplicitLocation UNKNOWN_LOCATION

Constructor Detail

ExplicitLocation

public ExplicitLocation(SourceLocator loc)

Create an ExpressionLocation, taking the data from a supplied JAXP SourceLocator

Parameters:

loc - the JAXP SourceLocator

ExplicitLocation

public ExplicitLocation(String systemId,
                int lineNumber,
                int columnNumber)

Create an ExpressionLocation corresponding to a given module, line number, and column number

Parameters:

systemId - the module URI

lineNumber - the line number

columnNumber - the column number

Method Detail

makeFromSax

public static ExplicitLocation makeFromSax(Locator loc)

Create an ExpressionLocation, taking the data from a supplied SAX Locator

Parameters:

loc - the SAX Locator

getSystemId

public String getSystemId()

Get the system ID (the module URI)

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface Location

Specified by:

getSystemId in interface Locator

Returns:

the system ID

getPublicId

public String getPublicId()

Get the Public ID

Specified by:

getPublicId in interface SourceLocator

Specified by:

getPublicId in interface Location

Specified by:

getPublicId in interface Locator

Returns:

always null in this implementation

getLineNumber

public int getLineNumber()

Get the line number

Specified by:

getLineNumber in interface SourceLocator

Specified by:

getLineNumber in interface Location

Specified by:

getLineNumber in interface Locator

Returns:

the line number

getColumnNumber

public int getColumnNumber()

Get the column number

Specified by:

getColumnNumber in interface SourceLocator

Specified by:

getColumnNumber in interface Location

Specified by:

getColumnNumber in interface Locator

Returns:

the column number

saveLocation

public Location saveLocation()

Get an immutable copy of this Location object. By default Location objects may be mutable, so they should not be saved for later use. The result of this operation holds the same location information, but in an immutable form.

Specified by:

saveLocation in interface Location
