Method Detail

getClause

public Clause getClause()

Get the clause being traced

Returns:

the clause in the FLWOR expression to which this ClauseInfo relates

getLocation

public Location getLocation()

Specified by:

getLocation in interface Locatable

getObjectName

public StructuredQName getObjectName()

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 Traceable

Returns:

the QName of the object declared or manipulated by this instruction or expression

getNamespaceResolver

public NamespaceResolver getNamespaceResolver()

Get the namespace bindings from the static context of the clause

Returns:

a namespace resolver that reflects the in scope namespaces of the clause

setNamespaceResolver

public void setNamespaceResolver(NamespaceResolver nsResolver)

Set the namespace bindings from the static context of the clause

Parameters:

nsResolver - a namespace resolver that reflects the in scope namespaces of the clause

getSystemId

public java.lang.String getSystemId()

Get the system identifier (URI) of the source stylesheet or query module containing the instruction. This will generally be an absolute URI. If the system identifier is not known, the method may return null. In some cases, for example where XML external entities are used, the correct system identifier is not always retained.

Returns:

the URI of the containing module

getLineNumber

public int getLineNumber()

Get the line number of the instruction in the source stylesheet module. If this is not known, or if the instruction is an artificial one that does not relate to anything in the source code, the value returned may be -1.

Returns:

the line number of the expression within the containing module

getPublicId

public java.lang.String getPublicId()

Return the public identifier for the current document event.

The return value is the public identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

Returns:

A string containing the public identifier, or null if none is available.

See Also:

getSystemId()

getColumnNumber

public int getColumnNumber()

Return the column number where the current document event ends. This is one-based number of Java char values since the last line end.

Warning: The return value from the method is intended only as an approximation for the sake of diagnostics; it is not intended to provide sufficient information to edit the character content of the original XML document. For example, when lines contain combining character sequences, wide characters, surrogate pairs, or bi-directional text, the value may not correspond to the column in a text editor's display.

The return value is an approximation of the column number in the document entity or external parsed entity where the markup triggering the event appears.

If possible, the SAX driver should provide the line position of the first character after the text associated with the document event. The first column in each line is column 1.

Returns:

The column number, or -1 if none is available.
