Constructor Detail

WithMemberNode

public WithMemberNode(ParseRegion region,
                      IdentifierNode name,
                      ParseTreeNode exp,
                      List<PropertyValueNode> memberPropertyList)

Constructs a formula specifying a member.

Parameters:

region - Source code region

name - Name of member being declared

exp - Expression for value of member

memberPropertyList - Collection of properties of member

Method Detail

getRegion

public ParseRegion 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 interface ParseTreeNode

Returns:

Region of the source code this node was created from, if it was created by parsing

unparse

public void unparse(ParseTreeWriter writer)

Description copied from interface: ParseTreeNode

Converts this node into MDX text.

Specified by:

unparse in interface ParseTreeNode

Parameters:

writer - Parse tree writer

getIdentifier

public IdentifierNode getIdentifier()

Returns the name of the member declared.

The name is as specified in the parse tree; it may not be identical to the unique name of the member.

Returns:

Name of member

getExpression

public ParseTreeNode getExpression()

Returns the expression to evaluate to calculate the member.

Returns:

expression

setExpression

public void setExpression(ParseTreeNode expression)

Sets the expression to evaluate to calculate the member.

Parameters:

expression - Expression

accept

public <T> T accept(ParseTreeVisitor<T> visitor)

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 interface ParseTreeNode

Parameters:

visitor - Visitor

Returns:

T, the specific return type of the visitor

getType

public Type 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 interface ParseTreeNode

Returns:

type of this expression

getMemberPropertyList

public List<PropertyValueNode> getMemberPropertyList()

Returns the list of properties of this member.

The list may be empty, but is never null. Each entry is a (name, expression) pair.

Returns:

list of properties

deepCopy

public WithMemberNode 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 interface ParseTreeNode

Returns:

The deep copy of this ParseTreeNode
