Method Detail
-
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,
nullif 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 benull.
-
getBody
public Scope getBody()
Returns catch body
-
setBody
public void setBody(Scope body)
Sets catch body, and sets its parent to this node.- Throws:
java.lang.IllegalArgumentException- if body isnull
-
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 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.
-
visit
public void visit(NodeVisitor v)
Visits this node, the catch var name node, the condition if non-null, and the catch body.
