package org.eclipse.jdt.core;
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 @noimplement This interface is not intended to be implemented by clients.

public interface ITypeParameter extends IJavaElement, ISourceReference {
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 the extends 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.
Throws: - JavaModelException – if this element does not exist or if an
exception occurs while accessing its corresponding resource
Returns: the names of the bounds

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 the extends keyword. The signatures may be either unresolved (for source types) or resolved (for binary types). See Signature for details. Throws: - JavaModelException –
if this element does not exist or if an exception occurs while accessing its corresponding resource.
