enableItems() - Method in class net.grelf.grip.ImTableMenu

Epoch - Class in net.grelf.astro

Represent astronomical epochs, such as B1950.0 or J2010.0.

Epoch(float) - Constructor for class net.grelf.astro.Epoch

Creates an Epoch assuming the type letter is 'J'.

Epoch(char, float) - Constructor for class net.grelf.astro.Epoch

Creates an Epoch with any type letter (but it must be 'B' or 'J' to make sense astronomically).
