IfStatement (Groovy 6.0.0-alpha-1)

org.codehaus.groovy.ast.stmt.IfStatement

```
public class IfStatement
extends Statement
```
Represents an if (condition) { then-block } else { else-block } conditional statement in Groovy. The if statement evaluates a boolean BooleanExpression and executes one of two code paths: the if block if the condition is true, or the else block (if present) if the condition is false. The else block defaults to an empty statement if not explicitly provided.

- Constructor Detail
  - public IfStatement(BooleanExpression booleanExpression, Statement ifBlock, Statement elseBlock)
    
    Constructs an IfStatement with a condition and then/else code blocks.
    Parameters:
    booleanExpression - the BooleanExpression to evaluate; must not be null
    ifBlock - the Statement to execute if the condition is true; must not be null
    elseBlock - the Statement to execute if the condition is false, or null for no else clause
- Method Detail
  - public BooleanExpression getBooleanExpression()
    
    Returns the BooleanExpression that is evaluated to determine which code path to execute.
    Returns:
    the BooleanExpression representing the condition
  - public Statement getElseBlock()
    
    Returns the Statement to execute when the condition is false. Returns EmptyStatement.INSTANCE if no else clause was specified.
    Returns:
    the else-block Statement
  - public Statement getIfBlock()
    
    Returns the Statement to execute when the condition is true.
    Returns:
    the then-block Statement
  - public String getText()
  - public void setBooleanExpression(BooleanExpression booleanExpression)
    
    Sets the BooleanExpression that is evaluated to determine control flow.
    throws:
    NullPointerException if booleanExpression is null
    
    Parameters:
    booleanExpression - the BooleanExpression to evaluate; must not be null
  - public void setElseBlock(Statement statement)
    
    Sets the Statement to execute when the condition is false. If null is provided, the else block is replaced with an empty statement.
    Parameters:
    statement - the else-block Statement, or null for no else clause
  - public void setIfBlock(Statement statement)
    
    Sets the Statement to execute when the condition is true.
    throws:
    NullPointerException if statement is null
    
    Parameters:
    statement - the then-block Statement; must not be null
