the defining class name.

Method Detail

addTypeAnnotationback to summary
protected void addTypeAnnotation(final List<Classfile.TypePathNode> typePath, final AnnotationInfo annotationInfo)

Implements abstract io.github.classgraph.TypeSignature.addTypeAnnotation.

Doc from io.github.classgraph.TypeSignature.addTypeAnnotation.

Add a type annotation to this type.

Parameters
typePath:List<Classfile.TypePathNode>

The type path.

annotationInfo:AnnotationInfo

@Override
equalsback to summary
public boolean equals(final Object obj)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

@Override
equalsIgnoringTypeParamsback to summary
public boolean equalsIgnoringTypeParams(final TypeSignature other)

Implements abstract io.github.classgraph.TypeSignature.equalsIgnoringTypeParams.

Doc from io.github.classgraph.TypeSignature.equalsIgnoringTypeParams.

Compare base types, ignoring generic type parameters.

Parameters
other:TypeSignature

the other TypeSignature to compare to.

Returns:boolean

True if the two TypeSignature objects are equal, ignoring type parameters.

Annotations
@Override
findReferencedClassNamesback to summary
protected void findReferencedClassNames(final Set<String> refdClassNames)

Overrides io.github.classgraph.TypeSignature.findReferencedClassNames.

Get the names of any classes referenced in the type signature.

Parameters
refdClassNames:Set<String>

the referenced class names.

Annotations
@Override
getClassNameback to summary
protected String getClassName()

Implements abstract io.github.classgraph.ScanResultObject.getClassName.

Return definingClassName, so that getClassInfo() returns the ClassInfo object for the containing class.

Returns:String

the defining class name.

Annotations
@Override
getNameback to summary
public String getName()

Get the name of the type variable.

Returns:String

The type variable name.

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

Annotations
@Override
parseback to summary
pack-priv static TypeVariableSignature parse(final Parser parser, final String definingClassName) throws ParseException

Hides io.github.classgraph.TypeSignature.parse.

Parse a TypeVariableSignature.

Parameters
parser:Parser

the parser

definingClassName:String

the defining class name

Returns:TypeVariableSignature

the type variable signature

Exceptions
ParseException:
if parsing fails
resolveback to summary
public TypeParameter resolve()

Look up a type variable (e.g. "T") in the defining method and/or enclosing class' type parameters, and return the type parameter with the same name (e.g. "T extends com.xyz.Cls").

Returns:TypeParameter

the type parameter (e.g. "T extends com.xyz.Cls", or simply "T" if the type parameter does not have any bounds).

Exceptions
IllegalArgumentException:
if a type parameter with the same name as the type variable could not be found in the defining method or the enclosing class.
setScanResultback to summary
pack-priv void setScanResult(final ScanResult scanResult)

Overrides io.github.classgraph.HierarchicalTypeSignature.setScanResult.

Doc from io.github.classgraph.ScanResultObject.setScanResult.

Set ScanResult backreferences in info objects after scan has completed.

Parameters
scanResult:ScanResult

the scan result

Annotations
@Override
toStringInternalback to summary
protected void toStringInternal(final boolean useSimpleNames, final AnnotationInfoList annotationsToExclude, final StringBuilder buf)

Implements abstract io.github.classgraph.HierarchicalTypeSignature.toStringInternal.

Doc from io.github.classgraph.HierarchicalTypeSignature.toStringInternal.

Render type signature to string.

Parameters
useSimpleNames:boolean

whether to use simple names for classes.

annotationsToExclude:AnnotationInfoList

toplevel annotations to exclude, to eliminate duplication (toplevel annotations are both class/field/method annotations and type annotations).

buf:StringBuilder

the StringBuilder to write to.

Annotations
@Override
toStringWithTypeBoundback to summary
public String toStringWithTypeBound()

Returns the type variable along with its type bound, if available (e.g. "X extends xyz.Cls"). You can get this in structured form by calling resolve(). Returns just the type variable if there is no type bound, or if no type bound is known (i.e. if resolve() returns null).

Returns:String

The string representation.
