getRegion
Description copied from interface:ParseTreeNode
Returns the region of the source code which this node was created from, if it was created by parsing.A non-leaf node's region will encompass the regions of all of its children. For example, a the region of a function call node
Crossjoin([Gender], {[Store].[USA]})
stretches from the first character of the function name to the closing parenthesis.Region may be null, if the node was created programmatically, not from a piece of source code.
- Specified by:
getRegion
in interfaceParseTreeNode
- Returns:
- Region of the source code this node was created from, if it was created by parsing
-
unparse
Description copied from interface:ParseTreeNode
Converts this node into MDX text.- Specified by:
unparse
in interfaceParseTreeNode
- Parameters:
writer
- Parse tree writer
-
getIdentifier
Returns the name of the set.- Returns:
- name of the set
-
getExpression
Returns the expression which calculates the set.- Returns:
- expression which calculates the set
-
setExpression
Sets the expression which calculates the set.- Parameters:
expression
- expression which calculates the set
-
accept
Description copied from interface:ParseTreeNode
Accepts a visitor to this MDX parse tree node.The implementation should generally dispatches to the
ParseTreeVisitor.visit(org.olap4j.mdx.SelectNode)
method appropriate to the type of expression.- Specified by:
accept
in interfaceParseTreeNode
- Parameters:
visitor
- Visitor- Returns:
- T, the specific return type of the visitor
-
getType
Description copied from interface:ParseTreeNode
Returns the type of this expression.Returns null if this node is not an expression, for instance a
SELECT
node.- Specified by:
getType
in interfaceParseTreeNode
- Returns:
- type of this expression
-
deepCopy
Description copied from interface:ParseTreeNode
Creates a deep copy of this ParseTreeNode object.Note: implementing classes can return the concrete type instead of ParseTreeNode (using Java 1.5 covariant return types)
- Specified by:
deepCopy
in interfaceParseTreeNode
- Returns:
- The deep copy of this ParseTreeNode
