Method Detail

getTestExpression

public AstNode getTestExpression()

Returns test expression

setTestExpression

public void setTestExpression(AstNode testExpression)

Sets test expression, and sets its parent.

Parameters:

testExpression - test expression

Throws:

java.lang.IllegalArgumentException - if testExpression is null

getTrueExpression

public AstNode getTrueExpression()

Returns expression to evaluate if test is true

setTrueExpression

public void setTrueExpression(AstNode trueExpression)

Sets expression to evaluate if test is true, and sets its parent to this node.

Parameters:

trueExpression - expression to evaluate if test is true

Throws:

java.lang.IllegalArgumentException - if expression is null

getFalseExpression

public AstNode getFalseExpression()

Returns expression to evaluate if test is false

setFalseExpression

public void setFalseExpression(AstNode falseExpression)

Sets expression to evaluate if test is false, and sets its parent to this node.

Parameters:

falseExpression - expression to evaluate if test is false

Throws:

java.lang.IllegalArgumentException - if falseExpression is null

getQuestionMarkPosition

public int getQuestionMarkPosition()

Returns position of ? token

setQuestionMarkPosition

public void setQuestionMarkPosition(int questionMarkPosition)

Sets position of ? token

Parameters:

questionMarkPosition - position of ? token

getColonPosition

public int getColonPosition()

Returns position of : token

setColonPosition

public void setColonPosition(int colonPosition)

Sets position of : token

Parameters:

colonPosition - position of : 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, then the test-expression, the true-expression, and the false-expression.

Specified by:

visit in class AstNode

Parameters:

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