jget-field

Arguments: class-ref-or-field field-or-instance &optional instance value

This function is associated with the macro jfield. The macro allows compile-time collection of java class names and method signatures. This information is used to generate a file of class and method definitions that may be loaded to initialize an application, and avoid the class and method lookup overhead in the body of the application.

The valid argument patterns for this operation are:

• class-ref field-name: to retrieve the value of a static field.
• class-ref field-name instance-ref: to retrieve the value of a class field of the instance.
• class-ref field-name primitive-value: to store primitive-value in a static field.
• class-ref field-name instance-ref value: to store value in a class field of the instance.
• class-ref field-name nil value: to store value in a static field (when value may be confused with an instance-ref).
• field-name instance: to retrieve the value of a field of the instance. The class is derived from the instance.
• field-name instance value: to store value in a field of the instance. The class is derived from the instance.
