Constructor Detail

MethodInfoDelegate

public MethodInfoDelegate(IFeatureInfo container,
                          IMethodInfo source)

Parameters:

container - Typically this will be the containing ITypeInfo

source - The method info source

Method Detail

getParameters

public IParameterInfo[] getParameters()

Specified by:

getParameters in interface IHasParameterInfos

Specified by:

getParameters in interface IMethodInfo

getReturnType

public IType getReturnType()

Specified by:

getReturnType in interface IMethodInfo

getCallHandler

public IMethodCallHandler getCallHandler()

Specified by:

getReturnDescription

public String getReturnDescription()

Specified by:

getReturnDescription in interface IMethodInfo

getExceptions

public List<IExceptionInfo> getExceptions()

Specified by:

getExceptions in interface IMethodInfo

getContainer

public IFeatureInfo getContainer()

Description copied from interface: IFeatureInfo

Get this feature's containing feature. May be null.

Specified by:

getContainer in interface IFeatureInfo

getOwnersType

public IType getOwnersType()

Description copied from interface: IFeatureInfo

Get this feature's owner's type. If this feature has no owner, this is the type of the feature itself. Typically, the only kind of feature w/o an owner is an ITypeInfo, so properties, methods, params, etc. s/b considered owned. Hence, ultimately an ITypeInfo's type will be the owner's type for any given feature.

Specified by:

getOwnersType in interface IFeatureInfo

getName

public String getName()

Description copied from interface: IFeatureInfo

Gets the programmatic name or identifier of this feature. Note this name should follow Java identifier naming conventions (alpha-num and underscores, but can't start with a digit).

Specified by:

getName in interface IFeatureInfo

Specified by:

getName in interface IMethodInfo

getDisplayName

public String getDisplayName()

Description copied from interface: IFeatureInfo

Gets the display name of this feature. There is no guarantee this display name is localized.

Specified by:

getDisplayName in interface IFeatureInfo

getDescription

public String getDescription()

Description copied from interface: IFeatureInfo

A full description of this feature.

Specified by:

getDescription in interface IFeatureInfo

isScriptable

public boolean isScriptable()

Description copied from interface: IAttributedFeatureInfo

True if this feature is exposed for scripting.

Specified by:

isDeprecated

public boolean isDeprecated()

Specified by:

isDeprecated in interface IAnnotatedFeatureInfo

Returns:

True if this feature is deprecated.

getDeprecatedReason

public String getDeprecatedReason()

Specified by:

getDeprecatedReason in interface IAnnotatedFeatureInfo

Returns:

The deprecation message, or null if the feature is not deprecated.

isDefaultImpl

public boolean isDefaultImpl()

Specified by:

isDefaultImpl in interface IAnnotatedFeatureInfo

Returns:

True if this feature is the default implementation e.g., default interface method

isVisible

public boolean isVisible(IScriptabilityModifier constraint)

Description copied from interface: IAttributedFeatureInfo

Determine if this feature is visible given a visibility constraint.

NOTE: implementers of this method are responsible for handling the null case, taken to mean that there are not scriptability constraints.

Specified by:

isVisible in interface IAttributedFeatureInfo

isHidden

public boolean isHidden()

Description copied from interface: IAttributedFeatureInfo

True if this feature is hidden. Hidden feature should not to be exposed to earthlings.

Specified by:

isHidden in interface IAttributedFeatureInfo

isStatic

public boolean isStatic()

Description copied from interface: IAttributedFeatureInfo

True if this feature is static, meaning the feature is not specific to a particular instance of the feature's containing type.

Specified by:

isStatic in interface IAttributedFeatureInfo

isPrivate

public boolean isPrivate()

Description copied from interface: IAttributedFeatureInfo

True if this feature is private. Private features are only accessible from within the type that owns them.

Specified by:

isPrivate in interface IAttributedFeatureInfo

isInternal

public boolean isInternal()

Description copied from interface: IAttributedFeatureInfo

True if this feature is internal. Internal features are accessible from within the type that owns them and from other types in the same namespace.

Specified by:

isInternal in interface IAttributedFeatureInfo

isProtected

public boolean isProtected()

Description copied from interface: IAttributedFeatureInfo

True if this feature is protected. Protected features are accessible from within the type that owns them and from derived containers.

Specified by:

isProtected in interface IAttributedFeatureInfo

isPublic

public boolean isPublic()

Description copied from interface: IAttributedFeatureInfo

True if this feature is public. Public features are not restricted.

Specified by:

isPublic in interface IAttributedFeatureInfo

isAbstract

public boolean isAbstract()

Specified by:

isAbstract in interface IAttributedFeatureInfo
