modifiers - field modifiers, a sum of one or more of PUBLIC,
PRIVATE,PROTECTED, STATIC,
FINAL,VOLATILE, TRANSIENT
constants defined in java.lang.reflect.Modifiertype - is a class representing the type of this field.name - is the name of this field.constValue - is the value of this field if it is static final,
null otherwise.| Method Detail |
public java.lang.Class getDeclaringClass()
getDeclaringClass in interface java.lang.reflect.Memberpublic java.lang.String getName()
getName in interface java.lang.reflect.Memberpublic int getModifiers()
MemberThis method returns modifiers of the method in the less significant half of the returned int, and the type of member in the other part. The members are encoded according to the following scheme.
1 - field 2 - method 3 - constructor ()
getModifiers in interface Membergnu.jel.reflect.Memberpublic java.lang.Class getType()
MemberFor fields it is the field type, for methods it is the method return value.
Primitive types are encoded as TYPE fields of corresponding reflection objects.
getType in interface Membergnu.jel.reflect.Memberpublic int getTypeID()
MemberFor performance and indexing reasons JEL encodes all Java types by integers. The encoding is defined in gnu.jel.TypesStack class. This method returns an integer encoding of this member's type.
getTypeID in interface Membergnu.jel.reflect.Memberpublic java.lang.Class[] getParameterTypes()
MemberIs there are no parameters (like for fields) it returns an array of length zero.

public java.lang.Object eval(java.lang.Object obj,
java.lang.Object[] params)
throws java.lang.Exception
MemberLooks up the value of the field or calls the method.
Not all members can be evaluated, for example non static final local fields can not since they exist only in compiler's memory.
