Method Details
-
setElementNode
Add a reference to the containing element node. This needs care because we don't want to retain links to the source stylesheet at run-time; it is therefore done only for static errors- Parameters:
node
- the containing element node
-
getElementNode
Get the reference to the containing element node, if available.- Returns:
- the containing element node, or null if not available or not applicable.
-
getElementName
Get the name of the containing element- Returns:
- the name of the containing element in the stylesheet
-
getAttributeName
Get the name of the containing attribute- Returns:
- the name of the containing attribute in the stylesheet. May be null if the XPath expression is contained in a text node
-
getColumnNumber
public int getColumnNumber()Get the column number. This column number is relative to the line identified by the line number. Column numbers start at 1.- Specified by:
getColumnNumber
in interfaceLocation
- Specified by:
getColumnNumber
in interfaceLocator
- Specified by:
getColumnNumber
in interfaceSourceLocator
- Returns:
- the column number, or -1 if the information is not available.
-
getSystemId
Get the system ID. This should be the system identifier of an XML external entity; if a stylesheet module comprises multiple external entities, the distinction should be retained. This means, for example, that an instruction in a stylesheet can have a different system identifier from its parent instruction. However, SAX parsers only provide location information at the element level, so when part of an XPath expression is in a different external entity from other parts of the same expression, this distinction is lost.The system identifier of a node is in general not the same as its base URI. The base URI is affected by xml:base attributes; the system identifier is not.
- Specified by:
getSystemId
in interfaceLocation
- Specified by:
getSystemId
in interfaceLocator
- Specified by:
getSystemId
in interfaceSourceLocator
- Returns:
- the system ID, or null if the information is not available.
-
getPublicId
Get the Public ID- Specified by:
getPublicId
in interfaceLocation
- Specified by:
getPublicId
in interfaceLocator
- Specified by:
getPublicId
in interfaceSourceLocator
- Returns:
- usually null
-
getLineNumber
public int getLineNumber()Get the line number. This line number is relative to the external entity identified by the system identifier. Line numbers start at 1. The value may be an approximation; SAX parsers only provide line number information at the level of element nodes.- Specified by:
getLineNumber
in interfaceLocation
- Specified by:
getLineNumber
in interfaceLocator
- Specified by:
getLineNumber
in interfaceSourceLocator
- Returns:
- the line number, or -1 if the information is not available.
-
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 interfaceLocation
- Returns:
- an immutable copy (which may be the original object, if it is already immutable)
-
