Method Detail

getExpression

public AstNode getExpression()

Returns the expression being thrown

setExpression

public void setExpression(AstNode expression)

Sets the expression being thrown, and sets its parent to this node.

Throws:

IllegalArgumentException} - if expression is null

toSource

public java.lang.String toSource(int depth)

Description copied from class: AstNode

Emits 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 null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

Specified by:

toSource in class AstNode

Parameters:

depth - the current recursion depth, typically beginning at 0 when called on the root node.

visit

public void visit(NodeVisitor v)

Visits this node, then the thrown expression.

Specified by:

visit in class AstNode

Parameters:

v - the object to call with this node and its children
