Constructor Detail

InfixExpression

public InfixExpression()

InfixExpression

public InfixExpression(int pos)

InfixExpression

public InfixExpression(int pos,
               int len)

InfixExpression

public InfixExpression(int pos,
               int len,
               AstNode left,
               AstNode right)

InfixExpression

public InfixExpression(AstNode left,
               AstNode right)

Constructs a new InfixExpression. Updates bounds to include left and right nodes.

InfixExpression

public InfixExpression(int operator,
               AstNode left,
               AstNode right,
               int operatorPos)

Constructs a new InfixExpression.

Parameters:

operatorPos - the absolute position of the operator

Method Detail

setLeftAndRight

public void setLeftAndRight(AstNode left,
                   AstNode right)

getOperator

public int getOperator()

Returns operator token – alias for Node.getType()

setOperator

public void setOperator(int operator)

Sets operator token – like Node.setType(int), but throws an exception if the operator is invalid.

Throws:

java.lang.IllegalArgumentException - if operator is not a valid token code

getLeft

public AstNode getLeft()

Returns the left-hand side of the expression

setLeft

public void setLeft(AstNode left)

Sets the left-hand side of the expression, and sets its parent to this node.

Parameters:

left - the left-hand side of the expression

Throws:

IllegalArgumentException} - if left is null

getRight

public AstNode getRight()

Returns the right-hand side of the expression

Returns:

the right-hand side. It's usually an AstNode node, but can also be a FunctionNode representing Function expressions.

setRight

public void setRight(AstNode right)

Sets the right-hand side of the expression, and sets its parent to this node.

Throws:

IllegalArgumentException} - if right is null

getOperatorPosition

public int getOperatorPosition()

Returns relative offset of operator token

setOperatorPosition

public void setOperatorPosition(int operatorPosition)

Sets operator token's relative offset

Parameters:

operatorPosition - offset in parent of operator token

hasSideEffects

public boolean hasSideEffects()

Overrides:

hasSideEffects in class AstNode

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 left operand, and the right operand.

Specified by:

visit in class AstNode

Parameters:

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