Method Detail

getKind

public SqlKind getKind()

Description copied from class: SqlNode

Returns the type of node this is, or SqlKind.OTHER if it's nothing special.

Overrides:

getKind in class SqlCall

Returns:

a SqlKind value, never null

See Also:

SqlNode.isA(java.util.Set<org.apache.calcite.sql.SqlKind>)

isExpanded

public boolean isExpanded()

Description copied from class: SqlCall

Whether this call was created by expanding a parentheses-free call to what was syntactically an identifier.

Overrides:

isExpanded in class SqlCall

setOperand

public void setOperand(int i,
                       SqlNode operand)

Description copied from class: SqlCall

Changes the value of an operand. Allows some rewrite by SqlValidator; use sparingly.

Overrides:

setOperand in class SqlCall

Parameters:

i - Operand index

operand - Operand value

setOperator

getOperator

public SqlOperator getOperator()

Specified by:

getOperator in class SqlCall

getOperands

getOperandList

public java.util.List<SqlNode> getOperandList()

Specified by:

getOperandList in class SqlCall

operand

public <S extends SqlNode> S operand(int i)

Overrides:

operand in class SqlCall

operandCount

public int operandCount()

Overrides:

operandCount in class SqlCall

getFunctionQuantifier

public SqlLiteral getFunctionQuantifier()

Overrides:

getFunctionQuantifier in class SqlCall

clone

public SqlNode clone(SqlParserPos pos)

Description copied from class: SqlNode

Clones a SqlNode with a different position.

Overrides:

clone in class SqlCall
