Method Detail

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

toString

public String toString()

Overrides:

toString in class Object

getCode

public Statement getCode()

This gets the code statement of the closure. You can read this method to find out what actions the closure is going to perform.

Returns:

the code statement of the closure

setCode

public void setCode(Statement code)

This sets the code statement of the closure. You can use this method in order to add more actions during the closure execution.

Parameters:

code - the new Statement

getParameters

public Parameter[] getParameters()

Returns:

an array of zero (for implicit it) or more (when explicit args given) parameters or null otherwise (representing explicit no args)

isParameterSpecified

public boolean isParameterSpecified()

Returns:

true if one or more explicit parameters are supplied

getVariableScope

public VariableScope getVariableScope()

setVariableScope

public void setVariableScope(VariableScope variableScope)

getText

public String getText()

Overrides:

getText in class ASTNode
