java.lang.Object bsh.Primitive
Wrapper for primitive types in Bsh. This is package public because it is used in the implementation of some bsh commands. See the note in LHS.java about wrapping objects.

boxType(java.lang.Class primitiveType)
Get the corresponding java.lang wrapper class for the primitive TYPE class. |
Primitive |
castToType(java.lang.Class toType,
int operation)
Cast this bsh.Primitive value to a new bsh.Primitive value This is usually a numeric type cast. |
boolean |
equals(java.lang.Object obj)
Primitives compare equal with other Primitives containing an equal wrapped value. |
static Primitive |
getDefaultValue(java.lang.Class type)
Get the appropriate default value per JLS 4.5.4 |
java.lang.Class |
getType()
Get the corresponding Java primitive TYPE class for this Primitive. |
java.lang.Object |
getValue()
Return the primitive value stored in its java.lang wrapper class |
int |
hashCode()
The hash of the Primitive is tied to the hash of the wrapped value but shifted so that they are not the same. |
