Method Details

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

getArguments

public Expression getArguments()

Specified by:

getArguments in interface MethodCall

setArguments

public void setArguments(Expression arguments)

getMethod

public Expression getMethod()

setMethod

public void setMethod(Expression method)

getMethodAsString

public String getMethodAsString()

This method returns the method name as String if it is no dynamic calculated method name, but a constant.

Specified by:

getMethodAsString in interface MethodCall

getObjectExpression

public Expression getObjectExpression()

setObjectExpression

public void setObjectExpression(Expression objectExpression)

getReceiver

public ASTNode getReceiver()

Specified by:

getReceiver in interface MethodCall

getText

public String getText()

Specified by:

getText in interface MethodCall

Overrides:

getText in class ASTNode

isSafe

public boolean isSafe()

Returns:

is this a safe method call, i.e. if true then if the source object is null then this method call will return null rather than throwing a null pointer exception

setSafe

public void setSafe(boolean safe)

isSpreadSafe

public boolean isSpreadSafe()

setSpreadSafe

public void setSpreadSafe(boolean value)

isImplicitThis

public boolean isImplicitThis()

Returns:

true if no object expression was specified otherwise if some expression was specified for the object on which to evaluate the method then return false

setImplicitThis

public void setImplicitThis(boolean implicitThis)

getGenericsTypes

public GenericsType[] getGenericsTypes()

setGenericsTypes

public void setGenericsTypes(GenericsType[] genericsTypes)

isUsingGenerics

public boolean isUsingGenerics()

getMethodTarget

public MethodNode getMethodTarget()

Returns:

the target as method node if set

setMethodTarget

public void setMethodTarget(MethodNode mn)

Sets a method call target for a direct method call. WARNING: A method call made this way will run outside of the MOP!

Parameters:

mn - the target as MethodNode, mn==null means no target

setSourcePosition

public void setSourcePosition(ASTNode node)

Description copied from class: ASTNode

Sets the source position using another ASTNode. The sourcePosition consists of a line/column pair for the start and a line/column pair for the end of the expression or statement

Overrides:

setSourcePosition in class ASTNode

Parameters:

node - - the node used to configure the position information

toString

public String toString()

Overrides:

toString in class Object
