Constructor Detail

GroupByNode

public GroupByNode()

GroupByNode

public GroupByNode(GroupByNode op)

Deep copy constructor.

GroupByNode

public GroupByNode(BOp[] args,
           Map<String,Object> anns)

Shallow copy constructor.

Method Detail

addGroupByVar

public void addGroupByVar(VarNode var)

getValueExpressions

public IValueExpression[] getValueExpressions()

Return the IValueExpressions for this GroupByNode.

toString

public String toString(int indent)

Description copied from class: CoreBaseBOp

The contract of this method at this level is under-specified. Sub-classes may choose between: - return a string representation of the object, similar to the use of CoreBaseBOp.toString() Or: - return a pretty-print representation of the object with indent Note that the former contract may or may not include recursive descent through a tree-like object, whereas the latter almost certainly does.

Specified by:

toString in interface BOp

Specified by:

toString in interface IQueryNode

Overrides:

toString in class CoreBaseBOp

Returns:

equals

public boolean equals(Object o)

Description copied from class: CoreBaseBOp

true if all arguments and annotations are the same.

Overrides:

equals in class CoreBaseBOp
