Constructor Detail

ExtExp

public ExtExp(String extId,
              String id,
              List<? extends ASTType> typeVarArgs,
              List<? extends Exp> args)

Default constructor. Sets this object as each type var arg's parent. Sets this object as each parameter type's parent.

Parameters:

extId - The extension id. Must be non-null.

id - The exp extension id. Must be non-null.

typeVarArgs - The arguments for the type vars. Must be non-null. Each element must be instance of ASTType.

args - The arguments. Must be non-null. Each element must be instance of Exp.

Method Detail

getArg

public Exp getArg(int index)

Gets the argat a particular index.

Parameters:

index - The index of the arg. Must be at least zero and at most less than the number of args.

Returns:

The arg at the given index.

getArgCount

public int getArgCount()

Gets the number of args.

Returns:

The number of args. At least zero.

setArgs

public void setArgs(List<? extends Exp> newArgs)

Sets the arguments. Sets this object as each argument's parent.

Parameters:

newArgs - The new arguments. Must be non-null. Each element must be instance of Exp.

setExtId

public void setExtId(String newExtId)

Sets the extension id.

Parameters:

newExtId - The new exp extension id. Must be non-null.

getExtId

public String getExtId()

Returns:

The extension id. Non-null.

setId

public void setId(String newId)

Sets the exp extension id.

Parameters:

newId - The new exp extension id. Must be non-null.

getId

public String getId()

Gets the exp extension id.

Returns:

The extension type id. Non-null.

setTypeVarArgs

public void setTypeVarArgs(List<? extends ASTType> newTypeVarArgs)

Sets the arguments for the type vars. Sets this object as each type var arg's parent.

Parameters:
