BinaryArithmeticOperatorNode

public BinaryArithmeticOperatorNode()

方法详细资料

initialize

public void initialize()
                throws antlr.SemanticException

从接口复制的说明: OperatorNode

Called by the tree walker during hql-sql semantic analysis after the operator sub-tree is completely built.

指定者:

initialize 在接口中 OperatorNode

抛出:

antlr.SemanticException

getDataType

public Type getDataType()

Figure out the type of the binary expression by looking at the types of the operands. Sometimes we don't know both types, if, for example, one is a parameter.

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.

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

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

getDisplayText

public String getDisplayText()

从接口复制的说明: DisplayableNode

Returns additional display text for the AST node.

指定者:

getDisplayText 在接口中 DisplayableNode

返回:

String - The additional display text.
