Method Detail

getCondition

public AstNode getCondition()

Returns if condition

setCondition

public void setCondition(AstNode condition)

Sets if condition.

Throws:

java.lang.IllegalArgumentException - if condition is null.

getThenPart

public AstNode getThenPart()

Returns statement to execute if condition is true

setThenPart

public void setThenPart(AstNode thenPart)

Sets statement to execute if condition is true

Throws:

java.lang.IllegalArgumentException - if thenPart is null

getElsePart

public AstNode getElsePart()

Returns statement to execute if condition is false

setElsePart

public void setElsePart(AstNode elsePart)

Sets statement to execute if condition is false

Parameters:

elsePart - statement to execute if condition is false. Can be null.

getElsePosition

public int getElsePosition()

Returns position of "else" keyword, or -1

setElsePosition

public void setElsePosition(int elsePosition)

Sets position of "else" keyword, -1 if not present

getLp

public int getLp()

Returns left paren offset

setLp

public void setLp(int lp)

Sets left paren offset

getRp

public int getRp()

Returns right paren position, -1 if missing

setRp

public void setRp(int rp)

Sets right paren position, -1 if missing

setParens

public void setParens(int lp,
             int rp)

Sets both paren positions

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, the condition, the then-part, and if supplied, the else-part.

Specified by:

visit in class AstNode

Parameters:

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