Constructor Detail- 
ExpressionStatementpublic ExpressionStatement() 
 - 
ExpressionStatementpublic ExpressionStatement(AstNode expr, boolean hasResult) Constructs a newExpressionStatementwrapping the specified expression. Sets this node's position to the position of the wrapped node, and sets the wrapped node's position to zero. Sets this node's length to the length of the wrapped node.- Parameters:
- expr- the wrapped expression
- hasResult-- trueif this expression has side effects. If true, sets node type to EXPR_RESULT, else to EXPR_VOID.
 
 - 
ExpressionStatementpublic ExpressionStatement(AstNode expr) Constructs a newExpressionStatementwrapping the specified expression. Sets this node's position to the position of the wrapped node, and sets the wrapped node's position to zero. Sets this node's length to the length of the wrapped node.- Parameters:
- expr- the wrapped expression
 
 - 
ExpressionStatementpublic ExpressionStatement(int pos, int len)
 - 
ExpressionStatementpublic ExpressionStatement(int pos, int len, AstNode expr)Constructs a newExpressionStatement- Parameters:
- expr- the wrapped- AstNode. The- ExpressionStatement's bounds are set to those of expr, and expr's parent is set to this node.
- Throws:
- java.lang.IllegalArgumentException- if- expris null
 
 
- 
 - 
Method Detail- 
setHasResultpublic void setHasResult() Called by the parser to set node type to EXPR_RESULT if this node is not within a Function.
 - 
getExpressionpublic AstNode getExpression() Returns the wrapped expression
 - 
setExpressionpublic void setExpression(AstNode expression) Sets the wrapped expression, and sets its parent to this node.- Throws:
- java.lang.IllegalArgumentException- } if expression is- null
 
 - 
hasSideEffectspublic boolean hasSideEffects() Returns true if this node has side effects- Overrides:
- hasSideEffectsin class- AstNode
- Throws:
- java.lang.IllegalStateException- if expression has not yet been set.
 
 - 
toSourcepublic java.lang.String toSource(int depth) Description copied from class:AstNodeEmits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.Note: if the parser was in error-recovery mode, some AST nodes may have nullchildren that are expected to be non-nullwhen no errors are present. In this situation, the behavior of thetoSourcemethod is undefined:toSourceimplementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.
 - 
visitpublic void visit(NodeVisitor v) Visits this node, then the wrapped statement.
