Method Detail

getAccessedVariable

public Variable getAccessedVariable()

setAccessedVariable

public void setAccessedVariable(Variable origin)

visit

public void visit(GroovyCodeVisitor visitor)

Overrides:

visit in class ASTNode

transformExpression

public Expression transformExpression(ExpressionTransformer transformer)

Description copied from class: Expression

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

Specified by:

transformExpression in class Expression

getText

public String getText()

Overrides:

getText in class ASTNode

getName

public String getName()

Description copied from interface: Variable

the name of the variable

Specified by:

getName in interface Variable

toString

public String toString()

Overrides:

toString in class Object

getInitialExpression

public Expression getInitialExpression()

Description copied from interface: Variable

expression used to initialize the variable or null of there is no initialization.

Specified by:

getInitialExpression in interface Variable

hasInitialExpression

public boolean hasInitialExpression()

Description copied from interface: Variable

returns true if there is an initialization expression
