Method Detail

canBeNull

public boolean canBeNull()

Description copied from class: JReferenceType

Returns true if it's possible for this type to be null.

Overrides:

canBeNull in class JReferenceType

getJavahSignatureName

public String getJavahSignatureName()

Overrides:

getJavahSignatureName in class JReferenceType

getJsniSignatureName

public String getJsniSignatureName()

Overrides:

getJsniSignatureName in class JReferenceType

isEnumOrSubclass

public JEnumType isEnumOrSubclass()

Description copied from class: JType

Returns the (closest) enum supertype if the type is a subclass of an enum; it returns this if this is a JEnumType} and null otherwise.

Overrides:

isEnumOrSubclass in class JType

getNonNull

public JNonNullType getNonNull()

Overrides:

getNonNull in class JReferenceType

getUnderlyingType

public JReferenceType getUnderlyingType()

Description copied from class: JReferenceType

If this type is a non-null type, returns the underlying (original) type.

Overrides:

getUnderlyingType in class JReferenceType

isAbstract

public boolean isAbstract()

isExternal

public boolean isExternal()

Description copied from class: JType

True if this class is provided externally to the program by the program's host execution environment. For example, while compiling for the JVM, JRE types are external types. External types definitions are provided by class files which are considered opaque by the GWT compiler. TODO(scottb): Means something totally different after AST stiching is done.

Overrides:

isExternal in class JType

isFinal

public boolean isFinal()

traverse

public void traverse(JVisitor visitor,
            Context ctx)

Description copied from interface: JVisitable

Causes this object to have the visitor visit itself and its children.

Parameters:

visitor - the visitor that should traverse this node

ctx - the context of an existing traversal
