Method Details

getReturnType

public String getReturnType()
                     throws JavaModelException

Description copied from interface: IMethod

Returns the type signature of the return value of this method. For constructors, this returns the signature for void.

For example, a source method declared as public String getName() would return "QString;".

The type signature may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details.

Specified by:

getReturnType in interface IMethod

Overrides:

getReturnType in class SourceMethod

Returns:

the type signature of the return value of this method, void for constructors

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.

See Also:

• IMethod

getSignature

public String getSignature()
                    throws JavaModelException

Description copied from interface: IMethod

Returns the signature of this method. This includes the signatures for the parameter types and return type, but does not include the method name, exception types, or type parameters.

For example, a source method declared as public void foo(String text, int length) would return "(QString;I)V".

The type signatures embedded in the method signature may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details.

Specified by:

getSignature in interface IMethod

Overrides:

getSignature in class SourceMethod

Returns:

the signature of this method

Throws:

JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource.

See Also:

• IMethod

isLambdaMethod

public boolean isLambdaMethod()

Description copied from interface: IMethod

Returns whether this method represents a lambda expression.

Specified by:

isLambdaMethod in interface IMethod

Overrides:

isLambdaMethod in class SourceMethod

Returns:

true if this method represents a lambda expression, false otherwise.

See Also:

• IMethod.isLambdaMethod()

closing

protected void closing(Object info)

Description copied from class: SourceRefElement

This element is being closed. Do any necessary cleanup.

Overrides:

closing in class SourceMethod

equals

public boolean equals(Object o)

Description copied from class: JavaElement

Returns true if this handle represents the same Java element as the given handle. By default, two handles represent the same element if they are identical or if they represent the same type of element, have equal names, parents, and occurrence counts.

If a subclass has other requirements for equality, this method must be overridden.

Overrides:

equals in class SourceMethod

See Also:

• Object.equals(java.lang.Object)

calculateHashCode

protected int calculateHashCode()

Overrides:

calculateHashCode in class SourceMethod

getElementInfo

public SourceMethodElementInfo getElementInfo(org.eclipse.core.runtime.IProgressMonitor monitor)
                                       throws JavaModelException

Description copied from class: JavaElement

Returns the info for this handle. If this element is not already open, it and all of its parents are opened. Does not return null. NOTE: BinaryType infos are NOT rooted under JavaElementInfo.

Overrides:

getElementInfo in class JavaElement

Throws:

JavaModelException - if the element is not present or not accessible

getHandleMemento

public void getHandleMemento(StringBuilder buff,
 boolean serializeParent)

getHandleMemento

public void getHandleMemento(StringBuilder buff)

Overrides:

getHandleMemento in class SourceMethod

See Also:

• JavaElement.getHandleMemento(StringBuilder)

getHandleMementoDelimiter

protected char getHandleMementoDelimiter()

Description copied from class: JavaElement

Returns the char that marks the start of this handles contribution to a memento.

Overrides:

getHandleMementoDelimiter in class SourceMethod

See Also:

• JavaElement.getHandleMemento()

getKey

public String getKey()

Description copied from interface: IMethod

Returns the binding key for this method only if the given method is resolved. A binding key is a key that uniquely identifies this method. It allows access to:

• generic info for parameterized methods
• the actual return type for references to Object.getClass()
• the actual parameter types and return type for references to signature polymorphic methods from class MethodHandle

If the given method is not resolved, the returned key is simply the java element's key.

Specified by:

getKey in interface IMethod

Overrides:

getKey in class SourceMethod

Returns:

the binding key for this method

See Also:

• invalid reference

  org.eclipse.jdt.core.dom.IBinding#getKey()

• BindingKey
• IMethod.isResolved()

isResolved

public boolean isResolved()

Description copied from interface: IMethod

Returns whether this method represents a resolved method. If a method is resolved, its key contains resolved information.

Specified by:

isResolved in interface IMethod

Overrides:

isResolved in class SourceMethod

Returns:

whether this method represents a resolved method.

resolved

public LambdaMethod resolved(Binding binding)

Overrides:

resolved in class SourceMethod
