@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.

equalsIgnoringTypeParamsback to summary
public boolean equalsIgnoringTypeParams(final TypeSignature other)

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

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

Parameters
other:TypeSignature

the other TypeSignature to compare to.

Returns:boolean

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

Overrides io.github.classgraph.TypeSignature.findReferencedClassNames.

Annotations
@Override
getBaseClassNameback to summary
public String getBaseClassName()

Returns:String

The name of the class.

getFullyQualifiedClassName()
getClassInfoback to summary
public ClassInfo getClassInfo()

Overrides io.github.classgraph.ScanResultObject.getClassInfo.

Get the ClassInfo object for the referenced class.

Returns:ClassInfo

The ClassInfo object for the referenced class, or null if the referenced class was not encountered during scanning (i.e. if no ClassInfo object was created for the class during scanning). N.B. even if this method returns null, loadClass() may be able to load the referenced class by name.

Annotations
@Override
getClassNameback to summary
protected String getClassName()

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

Doc from io.github.classgraph.ScanResultObject.getClassName.

The name of the class (used by getClassInfo() to fetch the ClassInfo object for the class).

Returns:String

the fully-qualified class name, for classloading.

Annotations
@Override
getFullyQualifiedClassNameback to summary
public String getFullyQualifiedClassName()

Get the name of the class, formed from the base name and any suffixes (suffixes are for inner class nesting, and are separated by '$'), but without any type arguments. For example, "xyz.Cls<String>.InnerCls<Integer>" is returned as "xyz.Cls$InnerCls". The intent of this method is that if you replace '.' with '/', and then add the suffix ".class", you end up with the path of the classfile relative to the package root.

For comparison, toString() uses '.' to separate suffixes, and includes type parameters, whereas this method uses '$' to separate suffixes, and does not include type parameters.

Returns:String

The fully-qualified name of the class, including suffixes but without type arguments.

getSuffixesback to summary
public List<String> getSuffixes()

Get all nested suffixes of the class (typically nested inner class names).

Returns:List<String>

The class suffixes (for inner classes), or the empty list if none.

getSuffixTypeAnnotationInfoback to summary
public List<AnnotationInfoList> getSuffixTypeAnnotationInfo()

Get a list of lists of type annotations for all nested suffixes of the class, one list per suffix.

Returns:List<AnnotationInfoList>

The list of lists of type annotations for the suffixes (nested inner classes), one list per suffix, or null if none.

getSuffixTypeArgumentsback to summary
public List<List<TypeArgument>> getSuffixTypeArguments()

Get a list of type arguments for all nested suffixes of the class, one list per suffix.

Returns:List<List<TypeArgument>>

The list of type arguments for the suffixes (nested inner classes), one list per suffix, or the empty list if none.

getTypeArgumentsback to summary
public List<TypeArgument> getTypeArguments()

Get any type arguments of the base class.

Returns:List<TypeArgument>

The type arguments for the base class.

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
