Constructor Detail

StandardFeatureCallArguments

public StandardFeatureCallArguments(java.util.List<XExpression> arguments,
                                    java.util.List<org.eclipse.xtext.common.types.JvmFormalParameter> parameters,
                                    boolean hasReceiver,
                                    ITypeReferenceOwner owner)

Method Detail

hasUnprocessedArguments

public boolean hasUnprocessedArguments()

Specified by:

hasUnprocessedArguments in interface IFeatureCallArguments

getNextUnprocessedArgumentSlot

public IFeatureCallArgumentSlot getNextUnprocessedArgumentSlot()

Specified by:

getNextUnprocessedArgumentSlot in interface IFeatureCallArguments

getArgument

public XExpression getArgument(int idx)

Description copied from interface: IFeatureCallArguments

Returns the argument expression at index idx. If there is a receiver, the index 0 returns null.

Specified by:

getArgument in interface IFeatureCallArguments

getDeclaredTypeForLambda

public final LightweightTypeReference getDeclaredTypeForLambda(int idx)

Description copied from interface: IFeatureCallArguments

Returns the declared parameter type for the argument at index idx. The semantics are similar to IFeatureCallArguments.getArgument(int) except for var arg parameters. Var arg parameters always return the component type of the last argument if asked for the type of the last or variable argument.

Specified by:

getDeclaredTypeForLambda in interface IFeatureCallArguments

internalGetParameterTypeForLambda

protected LightweightTypeReference internalGetParameterTypeForLambda(int idx)

getArgumentCount

public int getArgumentCount()

Description copied from interface: IFeatureCallArguments

Returns the number of argument expressions where the receiver is considered to be an argument, too.

Specified by:

getArgumentCount in interface IFeatureCallArguments

hasEmptyTrailingVarArg

public boolean hasEmptyTrailingVarArg()

Specified by:

hasEmptyTrailingVarArg in interface IFeatureCallArguments

internalGetArgument

protected XExpression internalGetArgument(int idx)

internalGetParameterType

protected LightweightTypeReference internalGetParameterType(int idx)

isProcessed

public boolean isProcessed(int argumentIndex)

Specified by:

isProcessed in interface IFeatureCallArguments

Parameters:

argumentIndex - the external argument index.

markProcessed

protected void markProcessed(int argumentIndex)

Parameters:

argumentIndex - the internal argument index.

toLightweightTypeReference

protected LightweightTypeReference toLightweightTypeReference(org.eclipse.xtext.common.types.JvmFormalParameter parameter)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
