Constructor Detail

ArithmeticOperation

public ArithmeticOperation()

ArithmeticOperation

public ArithmeticOperation(ArithmeticOperation.ArithmeticOperator operator,
                           SQLFragment[] args)

Method Detail

getOperator

public ArithmeticOperation.ArithmeticOperator getOperator()

setOperator

public void setOperator(ArithmeticOperation.ArithmeticOperator operator)

getSQLText

public java.lang.String getSQLText()

Returns the complete SQL representation for this Function fragment.

Specified by:

getSQLText in interface SQLFragment

Overrides:

getSQLText in class Operation

Returns:

a string representing the SQL text for this object.

getOperatorText

public java.lang.String getOperatorText()

Specified by:

getOperatorText in class Operation

equalsImpl

protected boolean equalsImpl(AbstractDBObject target)

Description copied from class: AbstractDBObject

Equals implementation for testing equality with another AbstractDBObject. Override this method (with exact signature) to customise the equality comparison. By default the type, name, schema and all properties in the properties map are compared so in general overrides should not be necessary.

Overrides:

equalsImpl in class Operation

getDataTypeID

public DBObjectID getDataTypeID()

Description copied from interface: SQLFragmentWithDatatype

Get the ID of the DataType of the SQLFragment. May be null if the DataType cannot be determined.

Specified by:

getDataTypeID in interface SQLFragmentWithDatatype

Overrides:

getDataTypeID in class Operation

getArithmeticOperator

public static ArithmeticOperation.ArithmeticOperator getArithmeticOperator(java.lang.String sql,
                                                                           int operandCount)

Gets the ArithmeticOperator for a given piece of sql that is exepcted to be an arithmetic operator.

Parameters:

sql - the sql to inspect

operandCount - the number of operands in the sql that the operator has.

Returns:

a ArithmeticOperator, or null if the sql is not recognized.
