true if a given class is of wrapped field's type or its subclass, false otherwise

isFinal

public boolean isFinal()

Returns:

true if a wrapped field is final, false otherwise

isModifiable

public boolean isModifiable()

Returns:

true if a wrapped field is not final or synthetic, false otherwise

isConcrete

Returns:

true if a wrapped field is of a concrete class type (not abstract or interface), false otherwise

isArray

public boolean isArray()

Returns:

true a wrapped field is of array type, false otherwise

getArrayContentType

public java.lang.Class<?> getArrayContentType()

Returns:

class type representing item type of this array field, null if this field is not of array type

getTypeArgumentCount

public int getTypeArgumentCount()

Returns:

number of field's generic arguments, 0 (zero) if it has none

getTypeArgument

public java.lang.Class<?> getTypeArgument(int index)

Parameters:

index - index of generic argument to return

Returns:

class type of wrapped field's index'th argument

Throws:

java.lang.IndexOutOfBoundsException - if index less than 0 or index + 1 greater than number of generic arguments
