Method Details
-
setConstructType
public void setConstructType(int type) Set the type of construct- Parameters:
type
- the type of contruct
-
getConstructType
public int getConstructType()Get the construct type- Specified by:
getConstructType
in interfaceInstructionInfo
- Returns:
- an integer identifying the kind of construct
-
setSystemId
Set the URI of the module containing the instruction- Parameters:
systemId
- the module's URI, or null indicating unknown
-
getSystemId
Get the URI of the module containing the instruction- Specified by:
getSystemId
in interfaceInstructionInfo
- Specified by:
getSystemId
in interfaceLocator
- Specified by:
getSystemId
in interfaceSourceLocator
- Returns:
- the module's URI, or null indicating unknown
-
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 interfaceInstructionInfo
- Specified by:
getLineNumber
in interfaceLocator
- Specified by:
getLineNumber
in interfaceSourceLocator
- Returns:
- the line number
-
setObjectName
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.- Parameters:
qName
- the name of the object, for example a function or variable name, or null to indicate that it has no name
-
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 interfaceInstructionInfo
- Returns:
- the name of the object, or null to indicate that it has no name
-
setProperty
Set a named property of the instruction- Parameters:
name
- the name of the propertyvalue
- the value of the property
-
getProperty
Get a named property of the instruction- Specified by:
getProperty
in interfaceInstructionInfo
- Parameters:
name
- name of the property- Returns:
- the value of the named property
-
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 interfaceInstructionInfo
- Returns:
- an iterator over the names of the properties
-
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 interfaceLocator
- Specified by:
getPublicId
in interfaceSourceLocator
- Returns:
- null
-
setColumnNumber
public void setColumnNumber(int column) Set the column number- Parameters:
column
- the column number of the instruction in the source module
-
getColumnNumber
public int getColumnNumber()Get the column number identifying the position of the instruction.- Specified by:
getColumnNumber
in interfaceLocator
- Specified by:
getColumnNumber
in interfaceSourceLocator
- Returns:
- -1 if column number is not known
-
getSystemId
Description copied from interface:LocationProvider
Get the URI of the document, entity, or module containing a particular location- Specified by:
getSystemId
in interfaceLocationProvider
- Parameters:
locationId
- identifier of the location in question (as passed down the Receiver pipeline)- Returns:
- the URI of the document, XML entity or module. For a SourceLocationProvider this will be the URI of the document or entity (the URI that would be the base URI if there were no xml:base attributes). In other cases it may identify the query or stylesheet module currently being executed.
-
getLineNumber
public int getLineNumber(long locationId) Description copied from interface:LocationProvider
Get the line number within the document, entity or module containing a particular location- Specified by:
getLineNumber
in interfaceLocationProvider
- Parameters:
locationId
- identifier of the location in question (as passed down the Receiver pipeline)- Returns:
- the line number within the document, entity or module, or -1 if no information is available.
-
getColumnNumber
public int getColumnNumber(long locationId) Description copied from interface:LocationProvider
Get the column number within the document, entity, or module containing a particular location- Specified by:
getColumnNumber
in interfaceLocationProvider
- Parameters:
locationId
- identifier of the location in question (as passed down the Receiver pipeline)- Returns:
- the column number within the document, entity, or module, or -1 if this is not available
-
