Constructor Detail

ExpExtension

public ExpExtension(ASTType expType,
                    String id,
                    List<String> typeVarIds,
                    List<TypedId> params,
                    BitSet paramLazyModifiers,
                    boolean variableParameterLength)

Default constructor. Sets this object as the return type's parent. Sets this object as each parameter type's parent.

Parameters:

expType - The exp type of this exp extension.

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

typeVarIds - The fixed type variable ids. Must be non-null. Each element must be instance of String. Each element must be distinct.

params - The fixed parameter types. Must be non-null.

paramLazyModifiers - The parameter type lazy modifiers. Must be non-null.

variableParameterLength - Indicates whether this type extension supports variable length parameters.

Method Detail

setExpType

public void setExpType(ASTType newExpType)

Sets the return type of this exp extension. Sets this object as the return type's parent.

Parameters:

newExpType - The new exp type of this exp extension. Must be non-null.

getExpType

public ASTType getExpType()

Gets the exp type of this exp extension.

Returns:

The exp type of this exp extension. Non-null.

setId

public void setId(String newId)

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.

getParameterLazyModifier

public boolean getParameterLazyModifier(int index)

Gets the parameter lazy modifier at a particular index.

Parameters:

index - The index of the parameter type. Must be at least zero and at most less than the number of fixed parameter types.

Returns:

boolean True, if the parameter is lazy. False, otherwise.

setParameterLazyModifiers

public void setParameterLazyModifiers(BitSet newParameterLazyModifiers)

Parameters:

index - The index of the parameter type. Must be at least zero and at most less than the number of fixed parameter types.

Returns:

The fixed parameter type at the given index.

getParameterCount

public int getParameterCount()

Gets the number of fixed parameter types.

Returns:

The number of fixed parameter types. At least zero.

setParameters

public void setParameters(List<TypedId> newParameters)
