public InstructionDetails()

Method Detail

setConstructType

public void setConstructType(int type)

Set the type of construct

getConstructType

public int getConstructType()

Get the construct type

Specified by:

getConstructType in interface InstructionInfo

setNamespaceResolver

public void setNamespaceResolver(NamespaceResolver resolver)

Set the namespace context for the instruction being traced. This is needed if the tracelistener wants to evaluate XPath expressions in the context of the current instruction

getNamespaceResolver

public NamespaceResolver getNamespaceResolver()

Get the namespace resolver to supply the namespace context of the instruction that is being traced

Specified by:

getNamespaceResolver in interface InstructionInfo

setSystemId

public void setSystemId(String systemId)

Set the URI of the module containing the instruction

Parameters:

systemId - the module's URI

getSystemId

public String getSystemId()

Get the URI of the module containing the instruction

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface InstructionInfo

Specified by:

getSystemId in interface Locator

Returns:

the module's URI

setLineNumber

public void setLineNumber(int lineNumber)

Set the line number of the instruction within the module

Parameters:

lineNumber - the line number

getLineNumber

public int getLineNumber()

Get the line number of the instruction within its module

Specified by:

getLineNumber in interface SourceLocator

Specified by:

getLineNumber in interface InstructionInfo

Specified by:

getLineNumber in interface Locator

Returns:

the line number

setObjectName

public void setObjectName(StructuredQName qName)

Set a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically.

getObjectName

public StructuredQName getObjectName(NamePool pool)

Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically.

Specified by:

getObjectName in interface InstructionInfo

Parameters:

pool -

setObjectNameCode

public void setObjectNameCode(int nameCode)

Set a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically.

setProperty

public void setProperty(String name,
                        Object value)

Set a named property of the instruction

getProperty

public Object getProperty(String name)

Get a named property of the instruction

Specified by:

getProperty in interface InstructionInfo

Parameters:

name - The name of the required property

Returns:

The value of the requested property, or null if the property is not available

getProperties

public Iterator getProperties()

Get an iterator over all the properties available. The values returned by the iterator will be of type String, and each string can be supplied as input to the getProperty() method to retrieve the value of the property.

Specified by:

getProperties in interface InstructionInfo

getPublicId

public String getPublicId()

Get the public ID of the module containing the instruction. This method is provided to satisfy the SourceLocator interface. However, the public ID is not maintained by Saxon, and the method always returns null

Specified by:

getPublicId in interface SourceLocator

Specified by:

getPublicId in interface Locator

Returns:

null

setColumnNumber

public void setColumnNumber(int column)

Set the column number

getColumnNumber

public int getColumnNumber()

Get the column number identifying the position of the instruction.

Specified by:

getColumnNumber in interface SourceLocator

Specified by:

getColumnNumber in interface Locator

Returns:

-1 if column number is not known

getInstructionInfo

public InstructionInfo getInstructionInfo()

Get the InstructionInfo details about the construct. This is to satisfy the InstructionInfoProvider interface.

Specified by:

getInstructionInfo in interface InstructionInfoProvider

getSystemId

public String getSystemId(long locationId)

Description copied from interface: LocationProvider

Get the URI of the document or module containing a particular location

Specified by:

getSystemId in interface LocationProvider

Parameters:

locationId - identifier of the location in question (as passed down the Receiver pipeline)

Returns:

the URI of the document or module.

getLineNumber

public int getLineNumber(long locationId)

Description copied from interface: LocationProvider

Get the line number within the document or module containing a particular location

Specified by:

getLineNumber in interface LocationProvider

Parameters:

locationId - identifier of the location in question (as passed down the Receiver pipeline)

Returns:

the line number within the document or module.
