BinaryLogicOperatorNode

public BinaryLogicOperatorNode()

方法详细资料

initialize

public void initialize()
                throws antlr.SemanticException

Performs the operator node initialization by seeking out any parameter nodes and setting their expected type, if possible.

指定者:

initialize 在接口中 OperatorNode

抛出:

antlr.SemanticException

mutateRowValueConstructorSyntaxesIfNecessary

protected final void mutateRowValueConstructorSyntaxesIfNecessary(Type lhsType,
                                                                  Type rhsType)

translate

protected void translate(int valueElements,
                         int comparisonType,
                         String comparisonText,
                         String[] lhsElementTexts,
                         String[] rhsElementTexts,
                         ParameterSpecification lhsEmbeddedCompositeParameterSpecification,
                         ParameterSpecification rhsEmbeddedCompositeParameterSpecification,
                         antlr.collections.AST container)

extractMutationTexts

protected static String[] extractMutationTexts(Node operand,
                                               int count)

extractDataType

protected Type extractDataType(Node operand)

getDataType

public Type getDataType()

从接口复制的说明: OperatorNode

Retrieves the data type for the overall operator expression.

指定者:

getDataType 在接口中 OperatorNode

指定者:

getDataType 在接口中 SelectExpression

覆盖:

getDataType 在类中 SqlNode

返回:

The expression's data type.

getLeftHandOperand

public Node getLeftHandOperand()

Retrieves the left-hand operand of the operator.

指定者:

getLeftHandOperand 在接口中 BinaryOperatorNode

返回:

The left-hand operand

getRightHandOperand

public Node getRightHandOperand()

Retrieves the right-hand operand of the operator.

指定者:

getRightHandOperand 在接口中 BinaryOperatorNode

返回:

The right-hand operand

setScalarColumnText

public void setScalarColumnText(int i)
                         throws antlr.SemanticException

从接口复制的说明: SelectExpression

Appends AST nodes that represent the columns after the current AST node. (e.g. 'as col0_O_')

指定者:

setScalarColumnText 在接口中 SelectExpression

参数:

i - The index of the select expression in the projection list.

抛出:

antlr.SemanticException - if a semantic error occurs
