Constructor Detail

LetExp

public LetExp(List<? extends ASTType> bindingTypes,
              List<String> bindingIds,
              List<? extends Exp> bindingExps,
              Exp exp)

Default constructor. Sets this object as each binding type's parent, each binding exp's parent, and the exp's parent. The number of binding types, binding ids, and binding exps must be equal.

Parameters:

bindingTypes - The types. Must be non-null. Each element must be instance of ASTType.

bindingIds - The ids. Must be non-null. Each element must be instance of String.

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

exp - The exp. Must be non-null.

Method Detail

getBindingCount

public int getBindingCount()

Gets the number of bindings.

Returns:

The number of bindings.

getBindingExp

public Exp getBindingExp(int index)

Gets a binding exp at a specified index.

Parameters:

index - The index of the argument. Must be between 0 and getBindingCount() - 1, inclusive.

Returns:

The binding exp at the specified index. Non-null.

setBindingExps

public void setBindingExps(List<? extends Exp> newBindingExps)

Sets the binding exps. Sets this object as each binding exp's parent.

Parameters:

newBindingExps - The new binding exps. Must be non-null. Each element must be instance of Exp.

getBindingId

public String getBindingId(int index)

Gets a binding id at a specified index.

Parameters:

index - The index of the argument. Must be between 0 and getBindingCount() - 1, inclusive.

Returns:

The binding id at the specified index. Non-null.

setBindingIds

public void setBindingIds(List<String> newBindingIds)

Sets the binding ids.

Parameters:

newBindingIds - The new binding ids. Must be non-null. Each element must be instance of Id.

getBindingType

public ASTType getBindingType(int index)

Gets a binding type at a specified index.

Parameters:

index - The index of the argument. Must be between 0 and getBindingCount() - 1, inclusive.

Returns:

The binding type at the specified index. Non-null.

setBindingTypes

public void setBindingTypes(List<? extends ASTType> newBindingTypes)

Sets the binding types. Sets this object as each binding type's parent.

Parameters:

newBindingTypes - The new binding types. Must be non-null. Each element must be instance of ASTType.

setExp

public void setExp(Exp newExp)

Sets the exp.

Parameters:

newExp - The new exp. Must be non-null.

getExp
