visit

public <X extends Exception> void visit(QueryModelVisitor<X> visitor)
                                 throws X extends Exception

Description copied from interface: QueryModelNode

Visits this node. The node reports itself to the visitor with the proper runtime type.

Throws:

X extends Exception

getSignature

public String getSignature()

Description copied from class: QueryModelNodeBase

Default implementation of QueryModelNode.getSignature() that prints the name of the node's class.

Specified by:

getSignature in interface QueryModelNode

Overrides:

getSignature in class QueryModelNodeBase

Returns:

The node's signature, e.g. SLICE (offset=10, limit=10).

equals

public boolean equals(Object other)

Description copied from interface: QueryModelNode

Returns true if this query model node and its children are recursively equal to o and its children.

Specified by:

equals in interface QueryModelNode

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

clone

public ProjectionElem clone()

Description copied from interface: QueryModelNode

Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.

Specified by:

clone in interface QueryModelNode

Overrides:

clone in class QueryModelNodeBase

Returns:

A deep clone of this query model node.

hasAggregateOperatorInExpression

public boolean hasAggregateOperatorInExpression()

Returns:

Returns the aggregateOperatorInExpression.

setAggregateOperatorInExpression

public void setAggregateOperatorInExpression(boolean aggregateOperatorInExpression)

Parameters:

aggregateOperatorInExpression - The aggregateOperatorInExpression to set.

getSourceExpression

public ExtensionElem getSourceExpression()

Returns:

Returns the sourceExpression.

setSourceExpression

public void setSourceExpression(ExtensionElem sourceExpression)

Parameters:

sourceExpression - The sourceExpression to set.
