Method Detail

getInitializer

public AstNode getInitializer()

Returns loop initializer variable declaration list. This is either a VariableDeclaration, an Assignment, or an InfixExpression of type COMMA that chains multiple variable assignments.

setInitializer

public void setInitializer(AstNode initializer)

Sets loop initializer expression, and sets its parent to this node. Virtually any expression can be in the initializer, so no error-checking is done other than a null-check.

Parameters:

initializer - loop initializer. Pass an EmptyExpression if the initializer is not specified.

Throws:

java.lang.IllegalArgumentException - if condition is null

getCondition

public AstNode getCondition()

Returns loop condition

setCondition

public void setCondition(AstNode condition)

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

Parameters:

condition - loop condition. Pass an EmptyExpression if the condition is missing.

Throws:

java.lang.IllegalArgumentException - if condition is null

getIncrement

public AstNode getIncrement()

Returns loop increment expression

setIncrement

public void setIncrement(AstNode increment)

Sets loop increment expression, and sets its parent to this node.

Parameters:

increment - loop increment expression. Pass an EmptyExpression if increment is null.

Throws:

java.lang.IllegalArgumentException - if increment 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.

Overrides:

toSource in class Scope

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 initializer expression, the loop condition expression, the increment expression, and then the loop body.

Overrides:

visit in class Scope

Parameters:

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