Method Detail

visit

public void visit(GroovyCodeVisitor visitor)

Overrides:

visit in class BinaryExpression

getVariableExpression

public VariableExpression getVariableExpression()

setLeftExpression

public void setLeftExpression(Expression leftExpression)

Overrides:

setLeftExpression in class BinaryExpression

setRightExpression

public void setRightExpression(Expression rightExpression)

Overrides:

setRightExpression in class BinaryExpression

transformExpression

public Expression transformExpression(ExpressionTransformer transformer)

Description copied from class: Expression

Return a copy of the expression calling the transformer on any nested expressions

Overrides:

transformExpression in class BinaryExpression

isMultipleAssignmentDeclaration

public boolean isMultipleAssignmentDeclaration()

This method tells you if this declaration is a multiple assignment declaration, which has the form "def (x, y) = ..." in Groovy. If this method returns true, then the left hand side is an ArgumentListExpression. Do not call "getVariableExpression()" on this object if this method returns true, instead use "getLeftExpression()".

Returns:

true if this declaration is a multiple assignment declaration, which means the left hand side is an ArgumentListExpression.
