Method Detail

init

public void init(Object leftOperand,
                 Object rightOperand,
                 Object operator,
                 Object methodName)

Initializer for a BinaryComparisonOperatorNode

Overrides:

init in class BinaryOperatorNode

Parameters:

leftOperand - The left operand of the comparison

rightOperand - The right operand of the comparison

operator - The name of the operator

methodName - The name of the method to call in the generated class

copyFrom

public void copyFrom(QueryTreeNode node)
              throws StandardException

Fill this node with a deep copy of the given node.

Overrides:

copyFrom in class BinaryOperatorNode

Throws:

StandardException

setForQueryRewrite

public void setForQueryRewrite(boolean val)

This node was generated as part of a query rewrite. Bypass the normal comparability checks.

Parameters:

val - true if this was for a query rewrite

isForQueryRewrite

public boolean isForQueryRewrite()

Was this node generated in a query rewrite?

Returns:

true if it was generated in a query rewrite.
