Field Detail

public static final Expression NO_ARGUMENTS

Constructor Detail

public MethodCallExpression(Expression objectExpression, String method, Expression arguments)

public MethodCallExpression(Expression objectExpression, Expression method, Expression arguments)

Method Detail

@Override public TupleExpression addExpression(Expression e)

public Expression getArguments()

@Override public List<Expression> getExpressions()

public GenericsType[] getGenericsTypes()

public Expression getMethod()

public String getMethodAsString()

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

public MethodNode getMethodTarget()

Returns:: the target as method node if set

public Expression getObjectExpression()

public ASTNode getReceiver()

public String getText()

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

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

public boolean isSpreadSafe()

public boolean isUsingGenerics()

public void setArguments(Expression arguments)

public void setGenericsTypes(GenericsType[] genericsTypes)

public void setImplicitThis(boolean implicitThis)

public void setMethod(Expression method)

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

public void setObjectExpression(Expression objectExpression)

public void setSafe(boolean safe)

@Override public void setSourcePosition(ASTNode node)

public void setSpreadSafe(boolean value)

public String toString()

public Expression transformExpression(ExpressionTransformer transformer)

public void visit(GroovyCodeVisitor visitor)
