Method Details

getVarName

public Name getVarName()

Returns catch variable node

Returns:

catch variable

setVarName

public void setVarName(Name varName)

Sets catch variable node, and sets its parent to this node.

Parameters:

varName - catch variable

getCatchCondition

public AstNode getCatchCondition()

Returns catch condition node, if present

Returns:

catch condition node, null if not present

setCatchCondition

public void setCatchCondition(AstNode catchCondition)

Sets catch condition node, and sets its parent to this node.

Parameters:

catchCondition - catch condition node. Can be null.

getBody

public Scope getBody()

Returns catch body

setBody

public void setBody(Scope body)

Sets catch body, and sets its parent to this node.

Throws:

IllegalArgumentException - if body is null

getLp

public int getLp()

Returns left paren position

setLp

public void setLp(int lp)

Sets left paren position

getRp

public int getRp()

Returns right paren position

setRp

public void setRp(int rp)

Sets right paren position

setParens

public void setParens(int lp,
 int rp)

Sets both paren positions

getIfPosition

public int getIfPosition()

Returns position of "if" keyword

Returns:

position of "if" keyword, if present, or -1

setIfPosition

public void setIfPosition(int ifPosition)

Sets position of "if" keyword

Parameters:

ifPosition - position of "if" keyword, if present, or -1

toSource

public 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, the catch var name node, the condition if non-null, and the catch body.

Specified by:

visit in class AstNode

Parameters:

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