Method Detail

canBePolymorphic

public boolean canBePolymorphic()

Description copied from class: JMethod

Returns true if this method can participate in virtual dispatch. Returns true for non-private instance methods; false for static methods, private instance methods, and constructors.

Overrides:

canBePolymorphic in class JMethod

getBody

public JMethodBody getBody()

Overrides:

getBody in class JMethod

getEnclosingType

public JClassType getEnclosingType()

Specified by:

getEnclosingType in interface HasEnclosingType

Overrides:

getEnclosingType in class JMethod

getNewType

public JNonNullType getNewType()

isConstructor

public boolean isConstructor()

Overrides:

isConstructor in class JMethod

isEmpty

public boolean isEmpty()

Returns true if this constructor does no real work. NOTE: this method does NOT account for any clinits that would be triggered if this constructor is the target of a new instance operation from an external class. TODO(scottb): make this method less expensive by computing in an external visitor.

needsVtable

public boolean needsVtable()

Description copied from class: JMethod

Returns true if this method can participate in instance dispatch.

Overrides:

needsVtable in class JMethod

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.

Specified by:

traverse in interface JVisitable

Overrides:

traverse in class JMethod

Parameters:

visitor - the visitor that should traverse this node

ctx - the context of an existing traversal

writeReplace

protected Object writeReplace()

Overrides:

writeReplace in class JMethod
