BinaryExpression (Groovy 6.0.0-alpha-1)

org.codehaus.groovy.ast.expr.BinaryExpression

```
public class BinaryExpression
extends Expression
```
Represents a binary operation between two expressions, such as addition, subtraction, comparison, or array/map access. The operation is specified by a Token indicating the operation type (e.g., +, -, ==, []). Supports safe operations where null objects are handled gracefully, returning null instead of throwing an exception.

- Constructor Detail
  - public BinaryExpression(Expression leftExpression, Token operation, Expression rightExpression)
    
    Creates a binary expression with the given left operand, operation, and right operand.
    Parameters:
    leftExpression - the left operand of the binary operation; must not be null
    operation - the operation token (e.g., Types.PLUS, Types.MINUS); may not be null
    rightExpression - the right operand of the binary operation; must not be null
  - public BinaryExpression(Expression leftExpression, Token operation, Expression rightExpression, boolean safe)
    
    Creates a binary expression with optional safe navigation support.
    Parameters:
    leftExpression - the left operand of the binary operation; must not be null
    operation - the operation token; may not be null
    rightExpression - the right operand of the binary operation; must not be null
    safe - if true, enables safe navigation (e.g., null-safe array access with ?[])
- Method Detail
  - public Expression getLeftExpression()
    
    Returns the left operand of this binary expression.
    Returns:
    the left operand Expression; never null
  - public Token getOperation()
    
    Returns the operation token representing the binary operation.
    Returns:
    the operation Token (e.g., Types.PLUS, Types.EQUAL); never null
  - public Expression getRightExpression()
    
    Returns the right operand of this binary expression.
    Returns:
    the right operand Expression; never null
  - public String getText()
  - public boolean isSafe()
    
    Indicates whether this binary expression uses safe navigation. Safe operations return null instead of throwing a NullPointerException when the left operand is null (e.g., obj?.property).
    Returns:
    true if safe navigation is enabled; false otherwise
  - public static BinaryExpression newAssignmentExpression(Variable variable, Expression rhs)
    
    Creates an assignment expression in which the specified expression is written into the specified variable. This is a factory method for constructing assignment operations like x = value.
    Parameters:
    variable - the target variable for assignment; must not be null
    rhs - the right-hand side expression to assign; must not be null
    Returns:
    a new BinaryExpression representing the assignment
  - public static BinaryExpression newInitializationExpression(String variable, ClassNode type, Expression rhs)
    
    Creates a variable initialization expression in which the specified expression is written into the specified variable name with an optional type annotation. This is a factory method for constructing typed variable declarations like String x = value.
    Parameters:
    variable - the variable name to initialize; must not be null
    type - the type annotation for the variable; may be null for untyped variables
    rhs - the right-hand side expression to assign; must not be null
    Returns:
    a new BinaryExpression representing the initialization
  - public void setLeftExpression(Expression leftExpression)
    
    Sets the left operand of this binary expression.
    Parameters:
    leftExpression - the new left operand; must not be null
  - public void setRightExpression(Expression rightExpression)
    
    Sets the right operand of this binary expression.
    Parameters:
    rightExpression - the new right operand; must not be null
  - public void setSafe(boolean safe)
    
    Sets whether this binary expression should use safe navigation.
    Parameters:
    safe - true to enable safe navigation; false otherwise
  - public String toString()
  - public Expression transformExpression(ExpressionTransformer transformer)
  - public void visit(GroovyCodeVisitor visitor)
