- io.github.classgraph.FieldInfo

All Implemented Interfaces:

public class FieldInfo
extends Object
implements Comparable<FieldInfo>, HasName
```
Holds metadata about fields of a class encountered during a scan. All values are taken directly out of the classfile for the class.

  - getConstantInitializerValue
```
public Object getConstantInitializerValue()
```
    Returns the constant initializer value of a field. Requires ClassGraph.enableStaticFinalFieldConstantInitializerValues() to have been called. Will only return non-null for fields that have constant initializers, which is usually only fields of primitive type, or String constants. Also note that it is up to the compiler as to whether or not a constant-valued field is assigned as a constant in the field definition itself, or whether it is assigned manually in static or non-static class initializer blocks or the constructor -- so your mileage may vary in being able to extract constant initializer values.

    The initializer value, if this field has a constant initializer value, or null if none.
  - getAnnotationInfo

```
public AnnotationInfo getAnnotationInfo(String annotationName)
```
    Get a the named non-Repeatable annotation on this field, or null if the field does not have the named annotation. (Use getAnnotationInfoRepeatable(String) for Repeatable annotations.)
    
    Parameters:
    
    annotationName - The annotation name.
    
    Returns:
    
    An AnnotationInfo object representing the named annotation on this field, or null if the field does not have the named annotation.

    Get a the named Repeatable annotation on this field, or the empty list if the field does not have the named annotation.

    Check if the field has a given named annotation.

    hashCode in class Object
    
    Returns:
    
    the hashcode
  - compareTo
```
