Constructor Detail

HierarchicalCondition

public HierarchicalCondition(TypedExpression baseExpression,
                             java.lang.String relationship,
                             TypedExpression referenceExpression,
                             MdmHierarchy hierarchy,
                             boolean negate,
                             boolean includeSelf)

Creates a HierarchicalCondition that evaluates to true if the baseExpression member of the hierarchy has the specified relationship to the referenceExpression member. If the includeSelf parameter is true, then the condition evaluates to true if the baseExpression member and the referenceExpression member are the same. If the negate parameter is true, then the condition evaluates to true if the baseExpression member does not have the specified relationship with the referenceExpression member.

Parameters:

baseExpression - A TypedExpression that evaluates to a member of a dimension hierarchy.

relationship - The value of one of the constants of this class that indicates the relationship to test.

referenceExpression - A TypedExpression that evaluates to a member of the dimension hierarchy.

hierarchy - The MdmHierarchy that contains the members of the hierarchy.

negate - A boolean that if true causes the HierarchicalCondition to evaluate to true if the base member does not have the specified relationship to the referenced member; if this parameter is false, then the condition evaluates to true if the base member does have the specified relationship to the referenced member.

includeSelf - A boolean that specifies whether or not to include the baseExpression member as a referenceExpression member that has the specified relationship.

HierarchicalCondition

public HierarchicalCondition(TypedExpression baseExpression,
                             java.lang.String relationship,
                             TypedExpression referenceExpression,
                             MdmHierarchy hierarchy,
                             boolean negate)

Creates a HierarchicalCondition that evaluates to true if the baseExpression member of the hierarchy has the specified relationship to the referenceExpression member. If the negate parameter is true, then the condition evaluates to true if the baseExpression member does not have the specified relationship with the referenceExpression member.

Parameters:

baseExpression - A TypedExpression that evaluates to a member of a dimension hierarchy.

relationship - The value of one of the constants of this class that indicates the relationship to test.

referenceExpression - A TypedExpression that evaluates to another member of the dimension hierarchy.

hierarchy - The MdmHierarchy that contains the members of the hierarchy.

negate - A boolean that if true causes the HierarchicalCondition to evaluate to true if the base member does not have the specified relationship to the referenced member; if this parameter is false, then the condition evaluates to true if the base member does have the specified relationship to the referenced member.

HierarchicalCondition

public HierarchicalCondition(TypedExpression baseExpression,
                             java.lang.String relationship,
                             TypedExpression referenceExpression,
                             MdmHierarchy hierarchy)

Creates a HierarchicalCondition that evaluates to true if the baseExpression member of the hierarchy has the specified relationship to the referenceExpression member.

Parameters:

baseExpression - A TypedExpression that evaluates to a member of a dimension hierarchy.

relationship - The value of one of the constants of this class that indicates the relationship to test.

referenceExpression - A TypedExpression that evaluates to another member of the dimension hierarchy.

hierarchy - The MdmHierarchy that contains the members of the hierarchy.

Method Detail

visit

public java.lang.Object visit(SyntaxObjectVisitor visitor,
                              java.lang.Object context)

Calls the visitHierarchicalCondition method of the SyntaxObjectVisitor and passes that method this HierarchicalCondition and an Object.

Specified by:

visit in class SyntaxObject

Parameters:

visitor - A SyntaxObjectVisitor.

context - An Object.

Returns:

The Object returned by the visitHierarchicalCondition method.

getBaseExpression

public TypedExpression getBaseExpression()

Gets the TypedExpression that evaluates to the member of the hierarchy that is the base of the condition test.

Returns:

A TypedExpression that evaluates to the base of the condition.

getReferenceExpression

public TypedExpression getReferenceExpression()

Gets the TypedExpression that evaluates to the member of the hierarchy that is the reference of the condition test.

Returns:

A TypedExpression that evaluates to the reference of the condition.

getHierarchy

public MdmHierarchy getHierarchy()

Gets the MdmHierarchy that contains the base and referenced members to test for the relationship.

Returns:

A MdmHierarchy that contains the members to test.

getRelationship

public java.lang.String getRelationship()

Gets the hieararchical relationship for which this HierarchicalCondition tests. The relationships are represented by the constants of this class, such as PARENT and ANCESTOR.

Returns:

A String that has the value of one of the constants of this class.

isNegated

public boolean isNegated()

Indicates whether this HierarchicalCondition tests for the negation of hierarchical relationship. For example, if this method returns true, then the HierarchicalCondition evaluates to true if the base expression does not have the specified relationship to the reference expression.

Returns:

A boolean that indicates whether this HierarchicalCondition tests for the negation of the condition.

includeSelf

public boolean includeSelf()

Indicates whether or not the base member is included in the members that have the specified relationship.

Returns:

A boolean that is true if the condition includes the base member as a member that has the specified relationship or false if it excludes the base member.
