org.apache.flex.abc.semantics.Name

public class Name
extends Object

A representation of a name.

All names are stored as multinames in the ABC, but this view of a name differentiates regular multinames, runtime multinames, and type names.

Field Detail

packageNs

public static final Namespace packageNs

The default package namespace for an unqualified name.

Constructor Detail

Name

public Name(String baseName)

Construct the simplest kind of Name: one whose kind is CONSTANT_Qname and whose namespace set contains the single package namespace with name "".

Parameters:

baseName - The unqualified name.

Name

public Name(Namespace ns,
    String baseName)

Construct a name whose kind is CONSTANT_Qname, with the namespace and base name specified.

Parameters:

ns - - the Namespace.

baseName - The unqualified name.

Name

public Name(Nsset multiname_qualifiers,
    String baseName)

Construct a Name whose kind is CONSTANT_Multiname.

Parameters:

multiname_qualifiers - The namespace set for the Name.

baseName - The base name for the Name.

Name

public Name(int kind,
    Nsset qualifiers,
    String baseName)

Construct a Name of any kind except CONSTANT_TypeName.

Parameters:

kind - The kind of the Name.

qualifiers - The namespace set for the name.

baseName - The base name for the Name.

Name

public Name(Name typename_base,
    Name typename_parameter)

Construct a Name of kind CONSTANT_TypeName, which represents a parameterized type such as C.<T>. getBaseName() and getQualifiers() will return null, but getTypeNameBase() returns the Name for type C, and getTypeNameParameter() returns the Name for type T.

Parameters:

typename_base - The Name for type C.

typename_parameter - The Name for type T.

Method Detail

isAttributeName

public boolean isAttributeName()

Returns:

true if the Name refers to an attribute.

toString

public String toString()

Overrides:

toString in class Object

getSingleQualifier

public Namespace getSingleQualifier()

Returns:

this Name's one and only Namespace qualifier.

getKind

public int getKind()

Returns:

the Name's kind byte.

See Also:

"values in ABCConstants"

getBaseName

public String getBaseName()

Returns:

the baseName

getQualifiers

public Nsset getQualifiers()

Returns:

the qualifiers

isTypeName

public boolean isTypeName()

Returns:

true if this name is a parameterized type name.

couldBeAnyType

public boolean couldBeAnyType()

Returns:

true if this name could be the Any type *

getTypeNameBase

public Name getTypeNameBase()

If this Name is for a parameterized type C., then this method returns the Name for type C.

Returns:

the Name for the base type of a parameterized type

getTypeNameParameter

public Name getTypeNameParameter()

If this Name is for a parameterized type C., then this method returns the Name for type T.

Returns:

the Name for the type parameter of a parameterized type

hashCode

public int hashCode()

Generate a composite hash code using the Name's fields' hashes.

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Determine equality by checking Name objects' corresponding fields.

Overrides:

equals in class Object

initTypeName

public void initTypeName(Name base,
                Name parameter)

Method to init a type name with a base name and parameter name. This method is to facilitate reading in a Name table from an ABC - the type name may refer to names which have not been read yet, so the values cannot be filled in until later. This will assert if this name is not a type name, or if it has already been initialized with values that are different than those passed in.

Parameters:

base - the base name this type name should use

parameter - the parameter name this type name should use

isRuntimeName

public boolean isRuntimeName()

Is this some type of runtime name?

Returns:

true if this is a runtime name.

runtimeNameAllowance

public int runtimeNameAllowance()

Compute the number of value stack elements this Name will need at evaluation.

Returns:

the number of value stack elements evaluating this Name requires.
