Class CalculatorExpr.SetExprBase.SetExpr

java.lang.Object

org.vishia.util.CalculatorExpr.SetExprBase.SetExpr

Direct Known Subclasses:

JZtxtcmdScript.JZcmdCalculatorExpr

Enclosing class:

CalculatorExpr.SetExprBase

public class CalculatorExpr.SetExprBase.SetExpr
extends java.lang.Object

Instances of this inner class are created with parenthesis expressions and for the whole expression. The reason is: store unary operators and the index for check boolean operations.

Constructor Detail

SetExpr

public SetExpr()

Creates a new instance of this class for sub expressions (parenthesis, arguments). This method should be overridden and should create the derived instance if a derived expression algorithm is used.

Parameters:

parent - may be null.

SetExpr

private SetExpr(CalculatorExpr.SetExprBase.SetExpr parent)

Method Detail

expr

public CalculatorExpr expr()

new_parenthesisExpr

public CalculatorExpr.SetExprBase.SetExpr new_parenthesisExpr()

Designates, that a expression in parenthesis is given, which should be calculated first. A existing actOperation will be stored, and the CalculatorExpr.SetExprBase.actOperation is set to null. Thus a new set operation will be created at first of the parenthesis expression. On runtime it forces a push to the stack.

Returns:

this

add_parenthesisExpr

public void add_parenthesisExpr(CalculatorExpr.SetExprBase.SetExpr val)

Closes an parenthesis expression. The actOperation will be stored and all bool check operations will be designated with the end index The next operations have to be invoked with val.parent and the val instance itself should be garbaged.

Parameters:

val -

new_boolOrOperation

public CalculatorExpr.SetExprBase.SetExpr new_boolOrOperation()

add_boolOrOperation

public void add_boolOrOperation(CalculatorExpr.SetExprBase.SetExpr val)

Designates the end of a multiplication operation. Takes the operation into the expression list.

Parameters:

val - this, unused

set_boolCheckAndOperation

public CalculatorExpr.SetExprBase.SetExpr set_boolCheckAndOperation()

set_boolCheckOrOperation

public CalculatorExpr.SetExprBase.SetExpr set_boolCheckOrOperation()

new_boolAndOperation

public CalculatorExpr.SetExprBase.SetExpr new_boolAndOperation()

add_boolAndOperation

public void add_boolAndOperation(CalculatorExpr.SetExprBase.SetExpr val)

Designates the end of a AND operation. Takes the operation into the expression list.

Parameters:

val - this, unused

set_boolNot

public void set_boolNot(java.lang.String val)

new_cmpOperation

public CalculatorExpr.SetExprBase.SetExpr new_cmpOperation()

add_cmpOperation

public void add_cmpOperation(CalculatorExpr.SetExprBase.SetExpr val)

set_cmpOperator

public void set_cmpOperator(java.lang.String val)

set_unaryOperator

public void set_unaryOperator(java.lang.String op)

new_addOperation

public CalculatorExpr.SetExprBase.SetExpr new_addOperation()

Designates the start of a new adding operation. The first start value should be taken into the stackOperation statement list as start operation.

Returns:

this

add_addOperation

public void add_addOperation(CalculatorExpr.SetExprBase.SetExpr val)

Designates the end of an add operation. Takes the operation into the expression list.

Parameters:

val - this, unused

new_subOperation

public CalculatorExpr.SetExprBase.SetExpr new_subOperation()

Designates the start of a new adding operation. The first start value should be taken into the stackOperation statement list as start operation.

Returns:

this

add_subOperation

public void add_subOperation(CalculatorExpr.SetExprBase.SetExpr val)

Designates the end of an add operation. Takes the operation into the expression list.

Parameters:

val - this, unused

new_multOperation

public CalculatorExpr.SetExprBase.SetExpr new_multOperation()

add_multOperation

public void add_multOperation(CalculatorExpr.SetExprBase.SetExpr val)

Designates the end of a multiplication operation. Takes the operation into the expression list.

Parameters:

val - this, unused

new_divOperation

public CalculatorExpr.SetExprBase.SetExpr new_divOperation()

add_divOperation

public void add_divOperation(CalculatorExpr.SetExprBase.SetExpr val)

Designates the end of a multiplication operation. Takes the operation into the expression list.

Parameters:

val - this, unused

set_charValue

public void set_charValue(java.lang.String val)

A character is stored as integer.

Parameters:

val -

set_intValue

public void set_intValue(int val)

Sets a value to the current operation.

Parameters:

val -

set_doubleValue

public void set_doubleValue(double val)

Sets a value to the current operation.

Parameters:

val -

set_textValue

public void set_textValue(java.lang.String val)

newDataAccessSet

protected DataAccess.DataAccessSet newDataAccessSet()

It is override-able to create an derived instance.

new_dataAccess

public DataAccess.DataAccessSet new_dataAccess()

Returns this because all methods of DataAccess.DataAccessSet are delegated in this class.

Returns:

add_dataAccess

public void add_dataAccess(DataAccess.DataAccessSet val)

onlyDataAccess

public DataAccess onlyDataAccess()

Returns the datapath if the expression contains only a datapath.

Returns:

null if the expression is more complex.

closeExprPreparation

public void closeExprPreparation()

This routine must be called at least. It adds a simple value to the operation list. If any second value was added already, the routine does nothing.

addToOperations

private void addToOperations()

addUnaryToOperations

private void addUnaryToOperations()

Adds the #actUnaryOperation to the expression statements.
