Method Details

getBreakLabel

public Name getBreakLabel()

Returns the intended label of this break statement

Returns:

the break label. null if the source code did not specify a specific break label via "break <target>".

setBreakLabel

public void setBreakLabel(Name label)

Sets the intended label of this break statement, e.g. 'foo' in "break foo". Also sets the parent of the label to this node.

Parameters:

label - the break label, or null if the statement is just the "break" keyword by itself.

getBreakTarget

public AstNode getBreakTarget()

Returns the statement to break to

Returns:

the break target. Only null if the source code has an error in it.

setBreakTarget

public void setBreakTarget(Jump target)

Sets the statement to break to.

Parameters:

target - the statement to break to

Throws:

IllegalArgumentException - if target is null

toSource

public String toSource(int depth)

Description copied from class: Jump

Jumps are only used directly during code generation, and do not support this interface.

Overrides:

toSource in class Jump

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 visits the break label if non-null.

Overrides:

visit in class Jump

Parameters:

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