Method Detail

getField

public static java.lang.reflect.Field getField(java.lang.Class c,
                                               java.lang.String name)

Return the field named name in Class c. Priviledged fields are made accessible if the JVM allows it.

Memoized.

getField

public static java.lang.reflect.Field getField(java.lang.Class c,
                                               java.lang.String name,
                                               boolean canAccessPrivateData)

reset

protected void reset()

Description copied from class: Reflector

Reset your classpath dependent state. This method can't be abstract.

Overrides:

reset in class Reflector

makeArgArray

public java.lang.Object[] makeArgArray(java.lang.Object[] code,
                                       LexicalEnvironment lexenv)

Description copied from class: Procedure

Take the code that represents a call, evaluate arguments in the calling lexical environment and put results into an argument array. Note that code[0] is the procedure, not an argument. For example, (p 1 2 3 (+ 2 2)) turns into the code {p, 1, 2, 3, {+, 2, 2}}, and if p has the parameter list (x y . z) then p.makeArgArray(code, lexenv) would return {1, 2, (3 4)}.

Overrides:

makeArgArray in class Procedure

makeArgArray

public java.lang.Object[] makeArgArray(Pair args)

Overrides:

makeArgArray in class Procedure

apply

public java.lang.Object apply(java.lang.Object[] args)

Description copied from class: Procedure

Apply the procedure to an argument list, which is represented as a parameter-oriented array. That is, if the procedure p has the parameter list (x y . z) and the call is (p 1 2 3 4) then args will be the array {1, 2, (3 4)}.

Overrides:

apply in class Procedure

getFieldValue

public java.lang.Object getFieldValue(java.lang.Object target,
                                      java.lang.reflect.Field f)

setFieldValue

public java.lang.Object setFieldValue(java.lang.Object target,
                                      java.lang.reflect.Field f,
                                      java.lang.Object value)
