Package org.eclipse.jdt.core
Interface ITypeParameter
- All Superinterfaces:
org.eclipse.core.runtime.IAdaptable
,IJavaElement
,ISourceReference
Represents a type parameter defined by a type or a method
in a compilation unit or a class file.
Type parameters are obtained using IType.getTypeParameter(String)
and
IMethod.getTypeParameter(String)
.
Note that type parameters are not children of their declaring type or method. To get a list
of the type parameters use IType.getTypeParameters()
for a type and use
IMethod.getTypeParameters()
for a method.
- Since:
- 3.1
- Restriction:
- This interface is not intended to be implemented by clients.

Method Details
-
getBounds
Returns the names of the class and interface bounds of this type parameter. Returns an empty array if this type parameter has no bounds. A bound name is the name as it appears in the source (without theextends
keyword) if the type parameter comes from a compilation unit. It is the dot-separated fully qualified name of the bound if the type parameter comes from a class file.- Returns:
- the names of the bounds
- Throws:
JavaModelException
- if this element does not exist or if an exception occurs while accessing its corresponding resource
-
getBoundsSignatures
Returns the signatures for this type parameter's bounds. The type parameter may have been declared as part of a type or a method. The signatures represent only the individual bounds and do not include the type variable name or theextends
keyword. The signatures may be either unresolved (for source types) or resolved (for binary types). SeeSignature
for details.- Returns:
- the signatures for the bounds of this formal type parameter
- Throws:
JavaModelException
- if this element does not exist or if an exception occurs while accessing its corresponding resource.- Since:
- 3.6

getDeclaringMember
IMember getDeclaringMember()Returns the declaring member of this type parameter. This can be either anIType
or anIMethod
.This is a handle-only method.
- Returns:
- the declaring member of this type parameter.
-
getTypeRoot
ITypeRoot getTypeRoot()Returns the Java type root in which this type parameter is declared.This is a handle-only method.
- Returns:
- the Java type root in which this type parameter is declared
